RAW MIX FOR MANUFACTURING CELLULAR CONCRETE |
摘要 |
<p>FIELD: manufacture of building structures. SUBSTANCE: raw mix comprises (wt %): 53-58 ash dust resulting from combustion of brown coals; 35-40 liquid glass with silica modulus of n=1 and density of p=1.52 g/cubic cm manufactured from microsilica; 5-7 water; and 0.15-0.2 aluminium powder. Such liquid glass comprises (wt %): up to 0.65 CaO; up to 0.5 Al<SB>2</SB>O<SB>3</SB>; up to 0.5 MgO; up to 1.25 Fe oxides; up to 0.2 K<SB>2</SB>O; and up to 7 carbon impurities such as graphite and carborundum. As compared with the prior art, the claimed compositions make it possible to increase construction quality of product by 47-68% and to reduce heat conductance thereof by 36-48%. Ash dust as finely dispersed component does not need additional grinding. EFFECT: simplified technology for manufacturing products, use of autoclave treatment and reduced manufacturing cost of products. 2 cl, 3 tbl</p> |
