CONSTRUCTION MORTAR Russian patent published in 2009 - IPC C04B38/10

Abstract RU 2359945 C1

FIELD: construction.

SUBSTANCE: invention pertains to construction materials and may be employed in production of building blocks. Construction mortar contains, wt %: cement - 22-29, metallurgical production moulding waste of the following composition, wt %: MgO - 0.27; Al₂O₃ - 1.0; SiO₂ - 96; PuS - 0.07; CaO - 0.55; Cr₂O₃ - 0.07; Fe₂O₃ - 0.3; Na₂O - 0.65; K₂O - 0.42; TiO₂ - 0.1, with fineness modulus of not more than 1.5 - 54.8-63.6; foaming additive "Kvin" based on sodium stearate C₁₇H₃₅COONa - 7-11; potassium permanganate - 0.2-0.4; water - 5-7.

EFFECT: improved heat recovery properties of foam-concrete due to reduced heat conductivity rate.
