    The present invention relates to a method of manufacturing terra cotta pavings which may be used for ground surfacing, said pavings not being frost-susceptible, being porous and water-permeable, comprising the steps of: intimately mixing 100 parts by volume of clay with 80 to 160 parts by volume of dry, non-compressed sawdust, essentially formed of particles whose average diameter is included between 0.5 mm and 4 mm; adding water such that the total water content is between 8 and 30% by weight with respect to the weight of the mixture; shaping the pavings under pressure; drying the pavings; baking the pavings at a temperature between the temperature, above which the terra cotta is not frost-susceptible, and the melting temperature of this clay, and subjecting the faces of the pavings to pumicing.

    (54) METHOD OF MANUFACTURING CERAMIC
    TILE
    one
    The invention relates to methods for producing ceramic tiles for covering sports fields.
    A known method of making bricks from a mixture of clay and sawdust, by mixing and raw materials, plastic molding or pressing, drying and firing 1.
    The disadvantage of this method is that the products do not have water permeability, which makes it impossible to use them to cover sports grounds.
    The closest to the proposed invention is a method of making ceramic tiles by mixing clay with a desiccant (sawdust), molding the product by pressing or stretching, depending on the water content in the mixture, 8-30 weight. % drying and roasting with subsequent machining (grinding) 2.
    The disadvantage of this method is that tiles with high strength and frost resistance are waterproof.
    The purpose of the invention is to obtain water-permeable tiles while maintaining mechanical strength and frost resistance.
    This goal is achieved by the fact that in the method of making ceramic tiles, by mixing clay, dry non-rammed sawdust and water in an amount of 8-30 wt. ° plastic forming or pressing of tiles, drying and calcining followed by grinding, mix 100 vol. including clay 80-160 about. h. sawdust average diameter of 0.5-4 mm.
    In addition, the molding is carried out by pulling under pressure above 15 kg / cm.
    and after firing, the tiles are quenched in water.
    Example 1. After measuring 100 vol. in the compacted state of the clay, i.e. the volume of clay in its natural state, clay is passed into the crusher, the stone removal device, through the abrading device and the rolls. 130 vol.% Are added to the clay treated in this way. including sawdust of timber in a dry, uncompacted state of the Scientific Research Institute, the average particle diameter of which is 1-3 mm after passing through a double sieve.

    The mixture thus prepared is passed through a humidifier-mixer and water is added to it in such an amount that the water content in the mixture is about 24 wt. % The mixture is then passed through a series of paddle mixers until a high degree of homogeneity is obtained. Carefully prepared mixture, highly uniform and homogeneous, without any lumps, is passed through a molding machine with a spinneret equipped with a deaeration system. The pressure in the molding machine is 15 kg / cm. The resulting straight parallelepiped tiles are then placed in a drying cabinet, flat, in order to avoid deformation. Drying is carried out by blowing first moist and then dry air for 72 hours at 80 ° C. Dry tiles are fired in a furnace at a temperature of about 970 ° C for 24 hours with a slow increase in temperature, and then subjected to quenching in water. The resulting tiles are ground and cleaned on all six sides. The tile has 48% of its internal volume open to water, i.e. 48% of the void. By immersing a tile in water, such a tile can be held in 25% of its volume in water, i.e. approximately 52% of its void is filled with water. Vessels consisting of connecting pores of equal diameter interconnected and passing through the tile in all directions are observed inside the tile. Porosity measurements show that 55% of the void consists of pores having a maximum diameter of 15jM, 10% of the void consists of pores with a maximum diameter And 90% of the void consists of pores with a maximum diameter of 0.3um. Using the proposed method will allow to produce tiles for coatings of sports fields, and tiles are frost-resistant, porous and permeable. Claims 1. Method of making ceramic tiles for covering the floors of sports fields by mixing clay, dry non-rammed sawdust and water in an amount of 8-30 weight. % plastic molding or pressing of tiles, drying, burning, followed by polishing, characterized in that, to obtain the permeable tiles while maintaining mechanical strength and frost resistance, 100 vol are mixed. including clay 80-160 about. h. sawdust average diameter of 0.5-4 mm. 2. A method according to claim 1, characterized in that the plastic molding is carried out by pulling under a pressure of more than 15 kg / cm 2. 3. A method according to claims. I and 2, characterized in that after firing, the tiles are quenched in water. Sources of information taken into account in the examination 1. M. Lundin.
