PRODUCTION METHOD OF MULTI-LAYER CONSTRUCTION PRODUCT BASED ON HIGHLY CONCENTRATED SUSPENSION OF SILICEOUS RAW MATERIALS (VERSIONS), METHOD FOR PRODUCTION OF MOULDING MIXTURE FOR BEARING FUNCTIONAL LAYERS OF PRODUCT (VERSIONS), METHOD FOR PRODUCTION OF HEAT INSULATION MATERIAL FOR MULTI-LAYER CONSTRUCTION PRODUCT, MULTI-LAYER CONSTRUCTION PRODUCT (VERSIONS)
FIELD: construction.;SUBSTANCE: three versions of method for manufacture of construction product, where moulding mixture is prepared for bearing layers by mixing of the following components, wt %: mineral filler 65-85 and finely dispersed binder - the rest based on highly concentrated suspension of siliceous raw materials with content of particles of less than 5 mcm - 20-50%, and humidity of 12-20%. Binder is modified by organo-mineral additive - 0.02-0.1 wt % from mass of dry substance of suspension or it additionally comprises plasticising additive - 2-5% from mass of dry substance. Layerwise moulding of product is carried out from moulding mixes for bearing layers and heat insulation layers installed between then, and strengthening according to three versions.;EFFECT: reduced time for manufacture of multi-layer products with preservation and improvement of mechanical strength, porosity, density, frost resistance.;25 cl, 10 ex, 10 tbl
