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.

Summary

Introduction

A rapid development in the production and the use of construction materials have been observed. There are new technologies and methods of constructing the buildings In its turn, it results in increasing requirements for construction materials, mostly to concrete. We can produce concrete of the required functionality while controlling the properties, creating the necessary structure of the material of a certain composition by means of technological impact on raw materials and predicting the results. All these factors have contributed to the development of a new concrete technology, the so-called self-compacting concrete (SCC). The search for new mineral additives based on local raw materials and industrial wastes, which can improve the physical and mechanical properties of self-compacting concrete, is a relevant task
