Cements and Additives for Producing High-Strength Concretes
On the basis of the analysis of the formation mechanism of the high-strength structure of cement stone which means the directed regulation of the phase composition and differentialporosity, the efficiency of water-reducing admixtures for producing high-strength concretes has been determined. It is established that an alternative to cement of increased activity withthe special chemical-mineralogical composition can be ordinary Portland cement of TSEM 1 type which is used in combination with high-active mineral additives and super-plasticizersor in combination with poly-component organic-mineral modifiers of MB type containing all ingredients required for achieving the high strength.Conclusions made on the basis of analysisthat for producing concretes of grades up to B 120 materials traditional for building industry can be used made it possible in a short time to organize in Russia the mass productionof high-strength concretes.
