Screenings of Crushing of Broken Slag as an Efficient Component of Concrete

Results of the experimental research concerning the use of chippings of slag stone as a mineral finely ground additive and a filler in fine structural concretes are presented. The rational composition of the finely ground additive in the course of the joint grinding of granulated blast furnace slag and gravel screenings was established. Compositions of fine concretes recommended for producing products by the method of off-formwork forming are presented. It is shown that the research conducted will help to rationally use the screenings of slag stone when producing fine slag concrete with reduced heat conductivity.
