Abstract

The article presents the results of a study of the properties of concrete, which can be used for the construction of hydraulic structures, the preliminary composition of which was determined using the ACI 211.4R-2008 standard. The effect of using the developed complex organo-mineral modifying additive consisting of thermal power plant fly ash, microsilicon SF-90 (MK90), methakaolin and polycarboxylate superplasticizer SR 5000F (SP) on changing the properties of hydraulic concrete was also studied.
