Features of structure formation during heat treatment of steel fiber reinforced concrete

In this article are listed the results of the theoretical and practical research in structure formation of steel fiber reinforced concrete during heat treatment. It was found that in a certain combination of the composition of the concrete matrix and the mode of heat treatment may receive volume-prestressed steel fiber reinforced concretes. Determined the residual deformations of various compositions of steel fiber reinforced concretes after heat treatment. Determined the main conditions ensuring prestressed state formation in steel fiber after heat treatment. The equations obtained which are showing the dependence of strength characteristics after heat treatment and the hardening in normal conditions. Founded that the formation of prestressed fiber carcass can increase strength characteristics of steel fiber reinforced concrete up to 25% in compare with the same compositions was curing in normal conditions.
