RAW COMPOSITION FOR MANUFACTURING OF CONSTRUCTION MATERIALS AND PRODUCTS Russian patent published in 2010 - IPC C04B28/30 C04B111/27 

FIELD: construction.

SUBSTANCE: present invention is related to raw compositions intended for manufacturing of construction materials and products on their basis. Raw composition for manufacturing of construction materials and products, including magnesia binder, which includes caustic magnesite and aqueous solution of chloride magnesium with density of 1.19-1.3 kg/l, mineral filler and additive, contains, as mineral filler, mixture of loose substances with specified surface of 3000-6500 cm²/g, which consists of TPP flue ash, quartz sand, kaolin and hydrophobic surface-active substance - surfactant powder - copolymer: vinyl acetate/vinyl alcohol or vinyl chloride / ethylene, or vinyl chloride /ethylene/vinyl aurate and additionally contains water-reducing additive, and also stabilising and water-reducing additive - water soluble ether of cellulose at the following ratio of components, wt %: caustic magnesite 28.0-40.0, quartz sand 30.0-42.0, TPP flue ash 10.0-14.0, kaolin 1.0-4.0, specified surfactant 0.5-0.9, water-reducing additive 0.01-0.30, water soluble ether of cellulose 0.01- 0.02, specified aqueous solution of magnesium chloride the rest. Invention is developed in dependent claims of formula.

EFFECT: increased mobility, vital capacity, strength, reduced water absorption.
