Abstract:
     The mixture consists of solid in 100 weight portions and water in 40-150 weight portions, and the solid part consists of solid active mineral 47-100 wt%, silica ash 0-35 wt%, concrete admixture 0-8 wt% and excitant 0-10 wt%. The solid active mineral has specific surface area of 400-1500 sq m/kg and average grain size of 0.5-45 micron and excitant is the compound of alkali metal and alkali earth metal. The solid active mineral is crushed to grain size smaller than 25, and then mixed with the silica ash 0-35 wt%, the concrete admixture, the excitant and water, and the mixture is then ground to form the required mixture.
