Microsilica as component of organic-mineral modifier for fine-aggregate concrete

摘要

Currently, modern heavy concrete including fine-aggregate ones are systems containing basic and additional components. Their production is not complete without the use of various mineral and organic additives. Such widespread additives include microsilica and various types of polymers. The effective use of additives, based on microsilica with polymers, allows creating heavy concretes with high performance properties. This topic is of a high relevance, so the research works were conducted to study the properties of fine-aggregate concrete, containing microsilica as an active mineral additive in the organic-mineral modifier composition in the Institute of new materials and technologies of Ural Federal University. This paper is devoted to the selection of composition of the organic-mineral modifier, based on the microsilica of OJSC 'Chelyabinsk Electrometallurgical Works'.
