METHOD FOR PRODUCING MULTILAYER wall blocks (optional), multi-layer building blocks (optional)

摘要

1. A method of manufacturing multilayer building blocks, comprising forming layers of the laminated wall block, including at least one external, at least one inner layer, if necessary, between the outer and inner layers are made further intermediate layer or intermediate layers, each layer made from mixtures whose composition comprises the following ingredients: concrete block, including crushed to the size of partitions of not less than 1 mm in an amount not less than 50% or expanded clay fractions with a grain size of not m than 1 mm and not less than 50%, any possible fractions the composition in an amount of cement is at least 20%, plasticizer in an amount of not less than 0.5%, the rest - water, respectively, in the manufacture of mixtures for the outer layer of the multilayer wall block is used, including expanded clay - at least 50% cement - at least 20%, plasticizer - not less than 0.5%, water - the rest, for the manufacture of the intermediate layer laminated wall block used, including expanded clay with various fractions with the size fractions at least 1 mm - at least 50% cement - at least 2 0%, plasticizer - not less than 0.5%, water - the rest, for the manufacture of an inner layer laminated wall block used, including sand - not less than 50% cement - at least 20%, plasticizer - not less than 0.5 %, water - the rest, selected quantities of ingredients for the layers of mixtures selected dimensional parameters block size parameters block layers, including length, width, thickness, shape and configuration of the laminated block, and the length, width, thickness, shape and configuration of each a layer for providing strength characteristics produced
