Annotation: The paper investigates the effect of partial replacement of Portland cement with mineral additives of technogenic origin: fly ash from Zuevskaya TPP, ground dump ash and slag mixture of Zuevskaya TPP and ground dump ash and slag mixture of Starobeshevskaya TPP in a percentage ratio of 10…30 %. Studies have shown that the introduction of 10 % to 30 % of one of the types of ash into the composition of the cement binder does not affect the uniformity of the volume change. All the studied compositions of the binder stone have rather high values of the ultimate compressive strength, both in the early and late periods of hardening. Thus, the possibility and expediency of partial replacement of cement with fly ash or dump ground ash and slag mixture from coal combustion at thermal power plants has been proved. Also, alternative binders can increase the raw material base for cement preparation and reduce the damage caused to the environment during its production.
Keywords: cement binder, ash and slag mixture, fly ash, strength, normal density, degree of hydration.
