GRANULATED COMPOSITE FILLER FOR SILICATE WALL PRODUCTS BASED ON QUARTZ SAND, COMPOSITION OF RAW MIX FOR MANUFACTURE OF SILICATE WALL PRODUCTS, METHOD FOR MANUFACTURING OF SILICATE WALL PRODUCTS AND SILICATE WALL PRODUCT

摘要

FIELD: construction.;SUBSTANCE: granulated composite filler for silicate wall products 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 - quartz sand 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% of mixture, and shell is shaped on nucleus surface by its rolling in 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. Raw mix for manufacture of silicate wall products includes the following components, wt %: above mentioned filler 5-40, quicklime 10.0-12.5, quartz sand 50.0-82.5. Method for production of silicate wall products includes preparation of above mentioned raw mix by mixing of its components, mixture moistening to molding humidity, pressure shaping of products and their autoclave treatment. Silicate wall product produced by above described method.;EFFECT: higher water resistance and frost resistance, reduced heat conductivity with preservation of strength parametres of silicate wall products, lower energy inputs in process of wall products making due to lower energy inputs during filler production.;4 cl, 1 ex, 2 tbl
