METHOD OF MAKING FACING TILES Russian patent published in 1995 - IPC

FIELD: manufacture of building materials. SUBSTANCE: layer of the cement-sandy slurry is applied on the sheet. After the bricks are covered with a thin layer of the epoxy compound they are put on this layer. Then the junctions between the bricks and their surface are again covered by the layer of the cement-sandy slurry. A new row of bricks covered with the layer of the cement-sandy slurry is laid on it. The process continues until a block of the required dimensions is obtained. After the epoxy compound and the cement-sandy slurry grow hard, the block is cut up into the plates. After polishing, burnishing and drying, the plates are covered with the mixture of the epoxy compound with acetone with the mass relation 1:2 at its expenditure of 100-300 grams per one square meter of the plates. Then they are placed into the desiccator at the temperature of 80-120 C. In case of using macroporous and cracked bricks, a filler made of stamped calcined brick is introduced into the epoxy compound after cutting up the block into plates. Large pores and cracks in the plates are sealed off with this filler. In case of using members of building brickwork in the form of blocks of irregular shape, which have been earlier used, they are piled into the rectangular blocks of the required dimensions. EFFECT: enhanced durability of tiles, economy of deficient synthetical binders and natural stone, facilitated manufacture. 2 cl, 1 dwg
