Abstract
The article substantiates the need to study the preliminary carbonization of concrete. Based on laboratory studies of concrete samples of compressive strength classes С12/15…С50/60, mixture compositions of workability grades P1 (OK = 4 cm), a system of calculated and experimental dependencies of initial carbonization КС0 = f(Ц) was obtained. The dependencies were checked using mathematical statistics methods, which showed the adequacy of the obtained dependencies.
Obtained depending on the preliminary carbonization КС0 = f(fG c,cube) on the guaranteed compressive strength of concrete for mixtures of workability grade P1.
By mathematical processing of the dependence coefficients derived from the dependence of the initial carbonization КС0 = f(Цр) and КС0 = f(fG c,cube) for classes of concrete in terms of compressive strength С12/15…С50/60, mixture compositions of workability grades G1 (8 s) and G2 (15 s).
