The modified solutions and concrete of the increased durability from local raw materials

The results of the study of the effect of modified additives on the rheological and mechanical properties of concrete and mortar when using limestone as a filler are presented. The aim of the work was to study the effect of modifiers on the rheology of the concrete mix and mortar and the physical and mechanical characteristics of concrete when using active aggregate. A chemical additive, the Glynium-Superplasticizer based on polycarboxylic ether polymers, was used. As a result, it was found that the addition of technogenic fine silica product together with micro silica and electrostatic precipitator strengthens the concrete.
