FIELD: construction. ^ SUBSTANCE: mixture for corrosion - resistant concrete contains binding agent received from mixed grinding of waterless sodium silicate having silicic module 2.6-2.8 with perlite reaching specific surface area of 400-450 m2/kg and filling material - quartzitic sandstone with 0.3-2.5 mm fractions size at the following components ratio, wt %: stated waterless sodium silicate 8-14, perlite 25-32, quartzitic sandstone with 0.3-2.5 mm fractions size 54-67. ^ EFFECT: enhanced corrosion resistance and strength of concrete, increased dissolution of waterless sodium silicate during fine grinding, shortened time of autoclaving. ^ 5 dwg, 6 ex |
