Regulation of Reaction Capacity of Fillers and Increasing Sulfate Resistance of Concretesby Combined Use of Low-Calcium Fly Ash and High-Active Metakaolin
Finding new effective ways for simultaneous regulation of the reaction capacity of fillers and increasing the sulfate resistance of concretes is one of the most important research and practicalproblems which need to be addressed to ensure durability of hydraulic structures. The article presents one of options of this problem solution due to introduction of several types ofmineral additives. The degree of low-calcium fly ash activation and its impact on the strength of cement stone have been also studied with the help of high-active metakaolin use.
