MIXTURE FOR MAKING CEMENT-CONTAINING CONSTRUCTION MATERIAL Russian patent published in 2019 - IPC C04B28/02 C04B7/13 C04B24/26 C04B111/20 C04B103/32 

FIELD: construction.

SUBSTANCE: invention relates to construction materials, specifically cement containing civil engineering construction materials, including to concrete and articles made from it, putty, plaster, trowels, repair, waterproofing, adhesive, structural dry mixtures. Cement-containing construction mixture contains cement, sand, modifiers, water and an active mineral additive containing aluminosilicate microspheres (cenospheres), amorphous silicon dioxide (microsilica) and high-calcium ash, with the following ratio of components, wt. %: cement 25.0–40.0, sand 5.0–30.0, active mineral additive 35.0–60.0, modifiers 0.2–2.0, water is balance. Particle size of amorphous silicon dioxide is 0.01–1 mcm, particle size of high-calcium ash is 1–25 mcm, and weight ratio of amorphous silicon dioxide and high-calcium ash is 1:3.

EFFECT: technical result is significant reduction in density of cement-containing construction materials while maintaining high operational characteristics, namely strength, heat conductivity, water-resistance, frost-resistance.
