On structures of industrial buildings and structures, in particular the mining and metallurgical complex, especially located near thermal devices, has the effect of temperature environment, changing the physical and mechanical properties of the materials from which these structures are made, and, as a consequence, affect their durability. This leads to the need to provide, in the reconstruction of buildings and structures, activities to increase their longevity by reducing the temperature influence of the environment. The purpose of research, the results of which are shown in the work is to obtain a porous Reactive powder concretes with improved strength and reduced shrinkage and water absorption by modifying its integrated additive composition which consists of iron-containing substance and a polyalcohol. Experiments established the influence of additives on the integrated strength of the porous reactive powder concrete, volumetric water absorption study concrete and water absorptionby capillary suction of concrete prepared without the use of complex additives and using supplements. The change in time of mass concrete can bewith and without it. Also investigated was the shrinkage of the porous concrete with or without complex additive it. As a result, it was found that the simultaneous introduction to the porous reactive powder concretes (pRPC) mineral complex containing iron polyalcohol and leads to increased compression strength, lower water absorption and shrinkage of said concrete. It is shown that the content of ferrous mineral complex (powder) and an organic component is pRPC extreme nature, i.e. attaching their content, providing the greatest strength of concrete and the least water absorption.
