A method for producing silicate wall products, the composition of the raw mix for the production of silicate wall products, granular silicate filler for wall products based on natural rocks and sedimentary silicate vysokokremnezemistyh wall products

2007 
1. A process for preparing silicate wall products, comprising mixing lime component and a filler comprising silica-lime-components and molding of construction products and their subsequent autoclave treatment, characterized in that as filler is used a granular composite with a grain size of 0.5-10.0 mm, consisting of a core and a shell, wherein the core used in the manufacture of milled to a specific surface of 150-250 m2 / kg of a mixture consisting of the above silica-containing component in de vysokokremnezemistoy natural sedimentary rocks and alkali metal hydroxide in a weight ratio 0,70-0,95: 0.05-0.30, as binder, an aqueous sodium silicate solution density of 1.2-1.3 g / cm3 at 0 , 1-7,0% by weight core beads, the formation of a protective shell on the surface of the core granules in a medium produce dry pulverulent mixture of the above components of lime and sodium silicofluoride in weight ratio of 0.85-0.95: 0,05-0 ,15; resulting granular silicate filler is introduced into the mixture after the acquisition of the strength as a result of curing at ambient temperature for not less than 2.1 MPa, with a raw material mixture is further added with stirring silica-components at the following ratio, wt.%: izvestsoderzhashchih komponent10,0-12,5kremnezemsoderzhaschy komponent50,0-82,5granulirovanny zapolnitel5-40! 2. Silicate composition for manufacturing building articles method of claim 1 comprising a filler component and a lime-containing and silica-izvestsoderzhashchih components otlichayuschayas
