FIELD: construction.SUBSTANCE: duplicating material to make tiled building blocks comprises webs of cellular and porous layers, which are thermally fixed to resist flaking from 0.01 to 0.19 kN/m, the cellular layer has surface density from 40 to 168 g/cmand comprises smooth anti-sorption threadlike elements, the porous material has apparent density from 10 to 50 g/m, and the duplicated material has thickness from 1.0 to 3.0 mm.EFFECT: higher quality of produced blocks due to prevention of mortar leakage to visible surface of blocks.8 cl, 1 tbl |
