RAW MATERIAL MIXTURE FOR PRODUCTION OF FOAM CONCRETE Russian patent published in 2014 - IPC C04B38/10 

FIELD: chemistry.

SUBSTANCE: invention relates to field of construction, in particular to compositions for obtaining foam concrete, intended for creation of efficient protecting structures. Raw material mixture for production of foam concrete includes Portland cement, lightening filling agent, foaming agent and mixing water, as said filling agent it contains hollow ceramic microspheres with bulk density 320-370 kg/m³ and size 40-100 mcm, as foaming agent - protein foaming agent, with the following component ratio, wt %: Portland cement 44.44-53.47, said microspheres 0.69-17.78, said foaming agent 0.025-0.03, water - the remaining part.

EFFECT: increased heat-insulating characteristics and density.
