Advantages: the main advantage of the technology is to improve the quality of concrete and reduce cement consumption.
Main characteristics: the technology provides for the enrichment of fine–grained natural sand with large fractions of granite screening, which makes it possible to increase the strength of concrete by 1.2-1.5 times and its frost resistance by 2-3 times, as well as resistance when exposed to concrete with chlorine salts and water resistance during cyclic tests. The main result is a 10-20% reduction in cement consumption per 1 m3 of concrete.
