Foamed concrete mixture based on nanostructured binder (versions), method of making articles from foamed concrete (versions)

FIELD: chemistry. SUBSTANCE: invention relates to the industry of construction materials and can be used in production of heat insulation and heat insulation-structural materials when making elements of buildings and other structures in industrial and civil construction. In three versions, the foamed concrete mixture contains non-cement nanostructured binder - highly concentrated suspension of silica-containing material containing 20-50% particles smaller than 5 mcm and moisture of 12-20%, which is pre-modified by successively adding an organomineral additive in amount of 0.02-0.10% and a plasticising additive in amount of 2-5% of the weight of dry substance of the suspension, a foaming agent and water in each of the said versions of ratios of components, a foaming agent indicated in each of the versions, as well as liquid sodium glass. The method of making articles from foamed concrete in each of the versions involves preparation of technical foam through mechanical processing of an aqueous solution of a foaming agent in a foam generator - mixer, mixing said solution with said binder, moulding articles from the obtained foamed mass, drying, hardening in each of the versions and then final drying. EFFECT: high mechanical strength. 9 cl, 6 ex, 16 tbl, 3 dwg
