The physical and mechanical properties of composite binders using fly ash from Ekibastuz GRES in the amount of 10-40% and plasticizing additive SP-1 were determined. On the basis of binders and complex additives, high-strength hydraulic concretes with a compressive strength of 24.5-27.3 MPa; tensile strength during bending - 4.5-5.1 MPa; water absorption – 1,9-2.2% by weight; water resistance – W 6-8; frost resistance – F 200-300 were obtained.
