Experimental Study of the Influence of the Aggregate Filler Fraction on the Abrasion Resistance of Ultra-Strong Concrete
The aim of the research is to study the influence of the filler fraction on the abrasion of ultra-strong concrete. The filler was selected taking into account the territorial accessibility. Dolomite and basalt were chosen as an aggregate, and coal slag was used as a partial replacement for SiO2. Measurements were carried out on the mass loss and the depth of wear of the prototypes. In the course of the experiments, it was found
