    Technical Field
    [001] The present invention relates to fire protection mortar and its use for fire protection. Technical Background of the Invention
    [002]The Rf RWS fire curve is used in the Netherlands for tunnel fire protection. It is based on realistic tunnel fire caused by a tanker in a tunnel that can lead to severe concrete fragmentation and therefore stability against tunnel damage. The tunnel's concrete lining, therefore, must be protected to ensure mobility and public safety. During the Rf RWS test, the fire curve reaches about 1200°C in about 5 min, then progressively increases to 1350°C in 60 min, then slowly decreases to 1200°C in 120 minutes. For submerged tunnels, the test criteria allow the maximum temperature (Tmax), at 380°C on the concrete surface, and only 250°C at 25mm inside the concrete surface. For drilled tunnels, the Tmax should not exceed 200-250°C (cf. Both et al., TNO Center for Fire Research and Tan et al., Tan et al., Ministry of Public Works, The Netherlands). Today, this standard is also increasingly used in other countries as criteria for tunnel fire protection, such as Belgium, Scandinavian countries, South Korea and, recently, the USA. The Rf CMH condition is similar to the Rf RWS curve, applicable in France (Figure 1).
    [003] Thus, the material used for protection against tunnel fires must withstand thermal shock, be resistant to the abrasion necessary for tunnel cleaning, and insensitive to attack by freezing / thawing. Preferably, it should be quartz-free and energy-efficient, for reasons of environmental protection and green footprint.
    [004] Only a few commercial sprayers are available on the market capable of withstanding such Rf RWS conditions. They are CAFCO FENDOLITE MII from Promat, FireBarrier 135 from Thermal Ceramics and Meyco Fireshield 1350 from BASF.
    [005] EP 0 986 525 by MBT Holding describes a spraying composition which mainly includes a cement binder, a heat treated sand shell and additives necessary for the spraying operation. The mortar is commercially available under the trade name MEYCO Fireshield 1350, with a cured density of about 1500 kg/m3. The material can pass the Rf RWS test, but with a thickness of 40 to 50 mm. The combination of high density and large thickness makes the spraying operation difficult, especially when spraying has to cover complex profiles such as steel structures.
    [006]EP 1 001 000 by Thermal Ceramics describes a spray which is claimed to be suitable for tunnels and contains saw dust which releases smoke at high temperatures. This material has been on the market under the designation FireBarrier 135. It employs aluminate and kaolin cement, with a cure density of about 1100 kg/m3, not only is it expensive, but it also shrinks on strong heating to such a degree that the product becomes cracked, a thickness of 38.5mm has to be sprayed to survive the Rf RWS test when tested by the TNO fire laboratory in the Netherlands.
    [007]Promat fire protection materials for tunnel fire protection are known in the market. EP 1 326 811 by Promat teaches a fire protection board in aluminate cement composition, xonotlite, functional fillers and additives. It has excellent performance in Rf RWS condition, however, it uses high percentage of aluminate cement as binder, the cost and energy consumption of raw materials are high. On the other hand, CAFCO FENDOLITE ® MII is a Promat sprayer that satisfies the Rf RWS condition. It mainly comprises OPC and exfoliated vermiculite. This fire protection spray has been established around the world, but offering good vermiculite becomes increasingly difficult. Only a few vermiculite mines are known to be asbestos-free, their deposits are decreasing as a result of industrial exploration, market prices are rising.
    [008]CN 101863640 A provides an environmentally friendly, fireproof colored coating for the tunnels, which comprises the following components in bulk parts: 10-50 parts cement, 40-90 parts expanded perlite, expanded vermiculite and precipitated calcium carbonate, 110 parts inorganic mineral fibers, 5-30 parts flame retardant systems, 0.1-5.0 parts rubber powder, 0.5-3.0 parts water reducing agents , air entraining agents and blowing agents and 0.5-2.0 parts of inorganic pigments.
    [009] The table below shows the range described in the document. Averaging these ranges, the total amount is 123.5 parts that have been normalized to the % weight in the last column of the table.

    [001] It follows that the amount of cement after normalization to 100% by weight is in the range of 8 to 40% by weight. This material is intended to be stable up to 1100°C Description of the Invention
    [002] It is an objective of the present invention to provide a fire protection mortar that overcomes at least some of the disadvantages of the prior art.
    [003] It is yet another objective of the present invention to provide a sprayer comprising a calcium silicate hydraulic cement, preferably free of vermiculite, with good freeze/thaw resistance and a cured density of less than 1200 kg/m3, preferably , between 500-1000 kg/m3, as fire protection for steel constructions and structures.
    [004] The objective is solved through a composition for the preparation of a fire protection mortar comprising: - 45 to 70% by weight of cement binder, - 8 to 20% by weight of calcite, - 8 to 20 % by weight of mica, - 0 to 5% by weight of xonotlite, - 0.1 to 20% by weight of expanded perlite, - 0.1 to 10% by weight of fibers, - 0.01 to 2% by weight of air entraining and foaming agent, - 0.01 to 4% by weight of processing aids.

    [008] The product, after preparation of a mortar and sprayed or cast and cured, will have satisfactory mechanical properties and good freeze/thaw resistance in fully exposed condition in accordance with EN12467. Once fired above 1250°C, cement, mica and calcite react with each other to form refractory crystalline phases containing mainly Alite (C3S), Belite (C2S) and Gelenite (C2AS) which are stable in the range of 1250-1400 °C and capable of providing passive fire protection in Rf RWS condition. This demonstrates that a cement-based matrix can become a refractory during a fire test in the range of 1200-1400°C. Typically, refractoriness at these elevated temperatures is achieved by an aluminate cement or ceramic based binder.
    [009] The material cured according to the invention can dehydrate and/or react in a staggered manner within a temperature range of 70-1250°C, therefore, able to step by step absorb heat and decrease the increase in heat and temperature transfer on the substrate to be protected.
    [0010] The cement binder of the present invention can be preferably selected from the group consisting of Portland cement (CEM I), composite Portland cement (CEM I), blast furnace slag cement (CEM III) , pozzolanic cement (CEM IV), other composite cement (CEM V) in accordance with EN 197-1 and their combinations.
    [0011] As Ordinary Portland Cement (OPC) is made at a much lower temperature than aluminate cement, it is available worldwide, using OPC reduces cost, saves energy and reduces emissions of CO2 compared to the aluminate cement-based product.
    [0012] Other hydraulic cements, such as calcium aluminate cement and sulfur aluminate cement, can also be used in place of the Portland cement of the present invention, but the costs will be higher.
    [0013] The calcite of the invention includes all forms of CaCO3 and its polymorphs, such as Aragonite and vaterite, it can be ground calcium carbonate (GCC) or precipitated calcium carbonate (PCC), used alone or in combination. CaCO3 decomposes at about 850°C to form CaO and CO2. CO2 gas has lower thermal conductivity than air at high temperatures, it improves thermal insulation. At a temperature > 1200°C, CaO reacts with cement and mica to form the necessary refractory phases. Preferred average particle size ranges up to 200 µm. If CEM II, CEM III, CEM IV or CEM V are used, which already contain CaCO3, the calcite dosage of the composition must be adapted accordingly, to avoid residual CaO from the high temperature reaction.
    [0014] It is important to note that hydrated lime or Ca(OH)2 should not be used in the present invention. Ca(OH)2 facilitates the formation of ettringite during cement hydration, which affects the formation of an optimal combination of C2S/C3S/C2AS refractory phases at elevated temperatures, leads to thermal insulation and/or inferior stability during the test of fire.
    [0015] The third component of the invention is mica, for example, selected from the group consisting of muscovite, phlogopite or biotite. At temperatures <1000° C, mica leads to better mechanical properties and decreases thermal shrinkage, at temperature > 1200° C, it decomposes and reacts with cement and CaO to form Alita, Belita, gelenite and therefore provides the stability of the material. On the other hand, this high temperature reaction also consumes a lot of energy, which reduces the heat flow from the fire side to the cold side. The mica range is 8-20%, the particle size is less than 3mm. Beyond this range, either the mica shows no effect at all; or the spray capacity will be affected.
    [0016] In some embodiments, the composition comprises xonotlite, preferably no more than 5% by weight.
    [0017] The xonotlite provides both thermal insulation and thermal stability at high temperatures. They are spherical particles made by a slurry reactor, under autoclave conditions, as described in EP 1 326 811. However, according to the invention, needle-shaped materials can also be used, such as, for example, the by-product in the processing of spherical xonotlite. At elevated temperatures, xonotlite dehydrates at about 800°C and then converts to wollastonite. This dehydration is a strongly endothermic reaction and consumes a lot of energy. The wollastonite thus formed has a theoretical melting point of 1530°C, which offers additional thermal stability beyond the aforementioned refractory phases. The presence of spherical xonotlite in the invention is greater than 5% by weight in order to maintain low cost and good sprayability 5.
    [0018] Expanded perlite is a light weight agent, has low cost and is available worldwide. At temperatures below 900°C, it reduces spray density while aiding thermal insulation; at temperatures above 900°C, the perlite softens and acts as a flux, promotes the solid-solid reaction between cement-CaO-mica to form refractory phases of the present invention. The preferred perlite dosage is 1-20%, the packing density in the range of 50-200 kg/m3, particle size below 6 mm, for the best pumpability and life of the spray machine.
    [0019] Although expanded perlite is a preferred lightweight filler material, other filler materials can also be used, such as, for example, pumice stones, multicellular glass, hollow ceramic spheres from power plant ash. Expanded vermiculite can also be used, although it is not the first choice of the present invention.
    [0020] Other components of the composition are fibers.
    [0021] The fibers of the present invention play an important role in the material. During the spraying process, the presence of fibers forms bridges surrounding the mixture. Together with the thixotropic agent action, they effectively keep the spray wet in place, the finish can be easily achieved. During cure, the fibers help reduce shrinkage with hardening and prevent surface fractures from spraying. When cured, the fibers act as reinforcement to improve the material's durability. The fibers are selected from the group consisting of, for example, PP fiber, PVA fiber, cellulose fiber, glass fiber including alkali resistant fiberglass, rock wool or mineral wool, steel fibers. The preferred fiber dosage is 0.1 to 10% by weight, the fiber length is below 15 mm.
    [0022] When necessary, such as for large thickness, metal mesh or plastic mesh can be used inside the mortar to ensure a good bond between the spray and the substrate, to avoid material fatigue during aging.
    [0023] Commonly used additives are present in the invention to facilitate mixing, slurry pumping, sprayability, setting hardening and durability. They are selected from the group consisting of set accelerator, set retarder, superplasticizer, water retaining agent, thixotropic agent, pumping aid, water repellent and redispersible polymers, used alone or in combination. Additives commonly used in the field can be used, the dosage is 0.01 - 4%.
    [0024] The air entrainment and/or foaming agent of the present invention not only aids in mixing and pumping the slurry, but also the freeze resistance of the cured spray by creating small capillary pores to prevent damage to the material during freeze/thaw cycles, when tested in fully saturated water conditions, exposing the temperature change of 20°C - 20°C for 100 cycles, as described by the standard EM 12467. The preferred dosage is 0.01 - two%.
    [0025] The composition of the present invention is a powder mixture. When mixed with water, it forms a fire protection mortar. Depending on the proposed use, the viscosity of the mortar can be adjusted by adding more or less water.
    [0026] Typically, the dry mix to water ratio is 30 to 70% by weight of dry mix and 70 to 30% water. For a spray application more water could be added than for the preparation of a product that is applied with a spatula or used for casting.
    [0027] Another modality of the invention is a fire protection product, which is obtained by hydraulic hardening of the fire protection mortar of the invention, after spraying or casting.
    [0028] Once cured, the bulk density is below 1200 kg/m3 and preferably between 500 and 1000 kg/m3.
    [0029] The material according to the invention can also be used as a repair or joining mortar to fill broken or burned parts of the material, ensuring the same or similar properties of all protection areas.
    [0030] Although created as a cement spray, the present invention can also be used to produce a frame or panel, by spraying or casting, followed by further molding to form a monolithic body, such as by filter press and Magnani process and flow-on.
    [0031] The cement mortar of the present invention is intended for more rigorous fire tests, such as the conditions of Rf RWS and Rf HCM. Of course, it can also withstand less severe fire scenarios, such as Rf RABT, Rf HC and Rf ISO conditions according to standard EN 1363-1 and ISO 834-1, as illustrated in figure 1.
    [0032] The following non-limiting examples further explain the invention and its modalities. EXAMPLE 1
    [0033] Test compositions and test results are in tables 1 - 2, all parts by weight. Test 1 is in accordance with the present invention; FB 135 is the commercially available Fire Barrier 135 spray product.
    [0034] The ingredients from table 1 and balance water are mixed by means of a planetary mixer in a mold through a spraying machine. After 28 days curing at 20°C, key properties relevant to fire protection, ie density, bending strength and thermal shrinkage at 1250°C, are tested. The results are shown in table 2. Thermal shrinkage is the average value of length, width and thickness. It is tested by placing the test samples in an oven, heating to the required temperature and holding for 3 hours. The dimension change is measured after cooling the sample to ambient conditions.
    [0035] According to table 2, the thermal shrinkage of test 1 (invention) is 1%, in contrast, that of FB 135 is 12.5%. The present invention (test 1) proves to be superior to the prior art in terms of remarkably improved thermal shrinkage. High temperature thermal shrinkage is one of the key parameters for the Fire test. If it is too high, the spray will fracture and fire will continue through the fracture openings, leading to material collapse and poor thermal insulation.
    Table 1: Example 1
    Table 2: Test Results EXAMPLE 2
    [0036] Two additional compositions (test 3, test 4) of the present invention (see table 3) and balanced with water are mixed by a planetary mixer to form a homogeneous cementitious mortar, then sprayed onto a concrete slab B35 With 150mm ceiling thickness by spraying machine, the spray is finished with spatula to have a good surface appearance with an equal thickness of 27.5mm. No metal mesh is used inside the spray. B35 concrete has a minimum compressive strength of 35 Mpa when cured in 28 days at 20°C.
    [0037] After 40 days of curing at 20° C, when mortar weight becomes constant, density and moisture (at 105° C) of the sprays are measured at about 850 - 900 kg/m3 and about 7%, respectively , as shown in Table 4.
    [0038] Full scale Rf RWS tests are done by placing the concrete slab on the ceiling, side by side with the Promat PROMATECT®-h panel (PT-H panel) in a thickness of 27.5 mm. PT-H panel is known for tunnel fire protection, usually it passes the RWS test at a thickness of 27.5mm. It is used here as a reference standard.
    [0039] The Rf RWS test (see figure 2) shows that test -3 and test -4 compositions remain stable in the ceiling throughout the fire test period and even after cooling. The maximum temperature (Tmax), an average thermocouple value, is measured at 356°C for the PT-H panel (reference), 348°C for the -3 test and 301°C for the -4 test of the present invention . From a statistical point of view, test -3 and PT-H panel have the same thermal insulation, test -4 can pass Rf RWS test in equal thickness of 27.5 mm. The -4 test shows remarkably lower Tmax thanks to the spherical Xonotlite effect, it is estimated to pass the Rf RWS test at 25 mm thick.
    [0040] After the Rf RWS test, the fire side of test sample-3 is collected and analyzed by XRD. The XRD quantification program identifies crystalline phases of Belite (C2S) 16.4%, Alite (C3S) 55.7%, gelenite (C2AS) 12.8%, another 15%. Mica, calcite or CaO are not detected, as evidence that they all reacted to the high temperatures.
    [0041] It is these in situ formed refractory phases that transform the cement mortar into a refractory mass with good thermal stability, which makes it capable of passing the Rf RWS test with remarkably small thickness <27.5 millimeters, compared to traditional sprays in the market.
    [0042] The freeze/thaw test of test composition-3 is done in accordance with EN12467, placing the sample saturated in water in a refrigerator, exposing the temperature change from 20° C to -20° C per cycle, 4 cycles per day, totaling 100 cycles. During testing, no surface flaking or delamination material is observed.
    [0043] After the freezing test, the flexural strength of the sample is tested and the results are shown in table 5. This demonstrates that the material of the present invention has no loss of strength during freeze/thaw cycles.
    Table 3: Example 2
    Table 4: Rf RWS test results
    Table 5: Freezing Resistance Test Results (EN12467)
    Table 6: Mechanical Properties
    [0044] When xonotlite is not present (Test 3), the results are already good for the intended application and the thermal insulation is superior to an internal plate used for RWS applications in tunnels (PROMATECT-H; Table 6).
    [0045] When xonotlite is used, the mortar can be further improved, both in thermal insulation (maximum temperature in Table 4) and in thermal stability (thermal shrinkage at 1250°C in Table 6). Xonotlite is a desirable component of the mortar of the invention. EXAMPLE 3
    [0046] Example 3 analyzes the properties of the product described in CN101863640 A.
    [0047] The materials described in the reference are: - Ordinary Portland Cement (OPC - Ordinary Portland Cement) - Calcium Aluminate Cement (CAC - Calcium Aluminate Cement and - Sulfur Aluminate Cement (SAC - Fast hardening Sulfur Aluminate Cement)
    [0048] As OPC is used according to the invention, this was also used for comparative experiments.
    [0049] Table 7 describes compositions prepared according to the disclosure of CN101863640 A. They are based on the average of formulations described in the document.
    [0050] MIX-1 uses a combination of expanded perlite, exfoliated vermiculite and Precipitated Calcium Carbonate (PCC).
    [0051] MIX-2 uses only expanded perlite and Precipitated Calcium Carbonate (PCC) without exfoliated vermiculite.
    Table 7: Comparative Testing
    [0052] The products were prepared and cured at 20°C for 28 days.
    [0053] Table 8 compares the density and resistance to bending and shrinkage of the materials with the material from Test -3 of Example 2.
    Table 8: Comparison Test Results
    [001]Figure 3 shows a photograph of the material after the fire test.
    [002]According to the reference, the product must be able to withstand the temperatures of a hydrocarbon fire. These test conditions require resistance to 1100°C, ie less than the RWS fire curve (see figure 1). MIX-1 and MIX-2 do not withstand the RWS fire test.
