Abstract RU 2361835 C1

FIELD: construction.

SUBSTANCE: granulated filler for concrete mix is arranged in the form of granules with size of 0.5-10.0 mm, comprising nucleus and shells, where nucleus is produced by granulation of mixture of the following components jointly ground to specific surface of 150-250 m2/kg - siliceous component - crushed glass - and alkaline metal hydroxide at their mass ratio of 0.70-0.95 : 0.05-0.30 with binder - aqueous solution of sodium silicate with density of 1.2-1.3 g/cm3 in amount of 0.1-7.0% from mixture, shell shaping on nucleus surface is carried out in medium of dry dusty mixture of jointly ground quicklime and sodium fluorsilicate at their mass ratio of 0.85-0.95 : 0.05-0.15, with further hardening to strength of at least 2.1 MPa. Concrete mix for manufacture of construction products includes the following components, wt %: above mentioned filler 5-40, binder 10-25, fine filler 15-45, water - the rest. Method for production of concrete construction products includes mixing of above mentioned mix components, moulding of construction products, soaking in molds and heat-and-moisture treatment at atmospheric pressure and temperature of 85-95°C. Concrete construction product produced by above described method.

EFFECT: higher water resistance and frost resistance, reduced heat conductivity with preservation of strength parametres of concrete construction products, lower energy inputs in process of products making due to lower energy inputs during filler production.
