Comparative analysis of the compression strength characteristics of polymer concrete modified by ultra-fine by-products silicon and aluminum industries

Abstract

Presently, one of the actual problems of concrete science is the improvement of concrete formulations by using industrial waste, ultra-fine by-products from the production of aluminum and silicon industry, as well as modification by means of additives. The aim of scientific research is development of new technologies for obtaining concrete with enhanced performance characteristics. The article provides an overview of the causes of concrete destruction and methods for increased physical-mechanical characteristics and of concrete. The results of a literature search on the experience of using silica fume and polymers in concrete are presented. The advantages and disadvantages of using silica fume and polymers in the composition of concrete are identified. A study was carried out to determine the effect of various modifying additives on the physical-mechanical characteristics of concrete. Experimental studies have been conducted on the joint use of silica fume and polymers in concrete mixture. The results of the study are: the optimal amount of silica fume is 10-20 %, the optimal amount of polymer is 1.0-3.5 %. On the basis of tests to determine the strength revealed that the class of concrete increased from B15 to B30 compared with the composition of the control sample.
