    Dry mortar mixture with grains of expanded glass.
    This invention relates to a dry mortar mixture which, after being mixed with water, forms a water-resistant and preferably frost-resistant mortar of thin layer thickness with which it is possible to make an equalizing, elastic layer on any substrate that complies with one or more of DIN18353, DIN19353 and DIN18156 and on which a covering floor covering can be applied, such as carpet, floor tiles or parquet. This mortar mixture contains grains of expanded glass.
    The dry mortar mixture of the invention is characterized by a glass mixture of expanded glass grains (glass granulate) with a grain size (preferably with a discontinuous grain distribution) d / D 0/8 (grains of minimum 0 and maximum 8.0 millimeters in diameter are present) , mixed in a ratio between 1: 1 and 1: 3, for example 1: 2 (eg 6 kg glass mixture on 12 kg binding mixture) with a dust-free or dust-free binding mixture of hydraulic binders and sand (stone granulate) in the weight ratio 1: 2 up to 1: 4, wherein one or more of the following additives are preferably added to the binding mixture (preferably at least 0.1 or 1.0 or 10% by weight per additive): powder elastomers (for example ground rubber); re-dispersible plastic powder (e.g., alkali-resistant copolymer, e.g. vinyl acetate-ethylene copolymer); alkali metal salt, anti-foaming agent; aniogenic or non-aniogenic surfactant (alkali resistant); hydroxycarboxylic acid (e.g. tartaric acid, citric acid, gluconic acid, glycolic acid) or its salt (e.g. lithium salt); conventional additives (for example, one or more of preservatives, thickeners, liquefaction agents).
    The mortar mixture is mixed with water at the construction site, for example 3.5 liters of water on 18 kg of dry mortar mixture, stirred into a plastic mortar and distributed on the substrate in a thickness of approximately between 5 and 25 mm with a smoother, a sheet or a scraper. The floor or wall covering (top layer) can be applied to the cured layer with the aid of, for example, a dispersion adhesive.
    The mortar can be used for a wooden or concrete floor or a wall (in particular to be tiled) in the bathroom, toilet, living room, kitchen, bedroom, hall or landing of a permanent home on land. Other applications are also conceivable.
    With the invention, a leveling layer of 800 kg can be realized, which traditionally weighs 4000 kg. The specific weight of the mixed mortar is 0.8 (of a traditional mortar at least 1.9). This mortar has a very short drying time compared to a traditional mortar.
    For the glass mixture, preferably one or more of the following applies: within the d / D the d is a minimum of 0. 2 or 0.4 or 0.5 and / or the D a maximum of 6.0 or 5.0 or 4 5 or 4.0 or 3.5; one or more grain sizes are missing within the d / D, for example grain sizes that are between 25% and 50% smaller than D and / or between 200% and 400% greater than d; a fraction of 0.5 / 1.0 and / or 2.0 / 4.0 is present (the d and / or D may deviate 10 or 20% from these values); absence of a fraction of 0.25 / 0.5 and / or 1, 0 / 2.0 (the d and / or D may deviate 10 or 20% from these values); one or more grain sizes between 1.0 and 2.0 millimeters (or a 10 or 20% of one or both deviating values) are missing (preferably all grain sizes); the mass percentage of the grain sizes present is substantially the same; the grain size distribution is around an average, so that an open structure is created; the average grain size distribution of the glass granulate is at least substantially a factor of 1.25 larger compared to the average grain size distribution of the sand or sand including the remaining mineral granulate; the amount of glass granulate of the smallest sieve size is less than 65% of the total glass mixture; the d50 value (grain size corresponding to the median of the sum of masses of the grains) of the glass is preferably between 1.0 and 3.0 mm; the cavity percentage of the unbound glass mixture is preferably between 25 and 45 vol%; instead of missing, a grain size indicated as missing may be present in a considerably lower mass percentage, for example at least 75% less; the specific weight of the glass granulate is between approximately 0.3 and 0.6 (specific weight of water = 1.0); contains at least two fractions and possibly a fraction between two fractions is missing (fraction = undivided group of grain sizes, for example all grain sizes between 0.5 and 1.0 or between 2.0 and 4.0, for example as commercially available).
    The hydraulic binder contains a content of mineral binder, for example a content of Portland cement, trasland cement, tras cement, iron portland cement, white cement, gypsum and / or aluminum melt cement. The binder is preferably present in an excess.
    The sand, preferably quartz sand, preferably has a grain size between 0 and 8 mm, more preferably at least 0.05 mm and / or at most 3 mm.
