Abstract

The subject matter of the research: fine-dispersed mineral ad-ditives based on raw materials and industrial wastes for the production of self-compacting concrete with prescribed high physical and mechanical characteristics, the use of which will be economically more justified by re-ducing energy consumption, evaluating their contact with superplasticizers.

The aim: the analysis of mineral additives based on local raw materials and industrial wastes combined with a superplasticizer for the production of self-compacting concrete with high physical and mechanical properties.

Materials and methods: scanning electron microscope JEOL JSM-6490 LV, X-ray fluorescence spectrometer for elemental analysis ARL OPTIM, X, ThermoTehno, Switzerland; gas analyzer Gank 4. The parameters to study are as follows: sedimentative and chemical composition of mineral additives, molding properties of a concrete mixture, mechanical properties of concrete.

The result: mineral additives with the use of local raw materials and in-dustrial wastes have been analyzed, optimal costs have been selected for the optimal hydration reaction behavior and the formation of a denser structure of self-compacting concrete.

Conclusions: studies of finely dispersed mineral additives in combination with a superplasticizer have been carried out in order to obtain self-compacting concrete with specified high physical and mechanical proper-ties.
