Rheological Behavior of Model Systems of Resource Matrix Efficient Self-Compacting Concrete

Abstract

This paper considers the problem of resource-intensive production of selfcompacting concrete. The possibility of using the by-product of the production of nitrogen phosphorus potash (NPK) in the OJSC "Mineral fertilizers" of the city of Rossosh as a component of self-compacting concrete is assessed. Thus, the article solves the problem associated with resource saving, namely, it proposes an alternative to natural filler in the form of technogenic calcium carbonate, dumps of which occupy a huge area and bring incontestable harm to the environment. The results of experimental studies of water systems "limestone flour + water", as well as "technogenic calcium carbonate + water" are given. The dependence of the watersolid ratio on the amount of the dosage of various additives at a constant viscosity of the systems is established.
