CRUDE MIXTURE FOR MAKING FOAMED CONCRETE ON NANOSTRUCTURED PERLITE BINDER (VERSIONS) Russian patent published in 2012 - IPC C04B38/10 B82B1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to the industry of construction materials and can be used in production of heat insulation materials when making elements of buildings and other structures in industrial and civil construction. In the first version, the crude mixture for making foamed concrete contains the following, wt %: non-cement nanostructured binder - highly concentrated suspension of natural perlite in water with 40-70% content of particles with size less than 5 mcm and 14-28% moisture content 63.70-67.9, protein foaming agent 0.32-0.60, water 31.80-35.76. In the second version, the crude mixture for making foamed concrete contains non-cement nanostructured binder - highly concentrated suspension of natural perlite in water with 40-70% content of particles with size less than 5 mcm and 14-28% moisture content 63.70-67.87, protein foaming agent 0.12-0.40, synthetic foaming agent 0.20-0.28, water 31.73-35.70.

EFFECT: design of highly effective heat insulating ecologically clean foamed concrete based on a new type of non-cement nanostructured binder with preservation and improvement of physical-mechanical and thermal-physical properties.
