The paper presents the results of long-term studies in production of high-strength concrete with coarse aggregate. The results of physical and mathematical tests of rubble stone density and strength are given. The heavy concrete experimental compositions are developed: the dependences of concrete strength on water-cement ratio, consumption of mixing water, binder and aggregate are obtained. The high-strength concrete tested is characterized by a linear relationship between the concrete compression strength and the concrete mix density.
The studies conducted allow developing a series of remedial compositions for repair and renewal operations in construction.
