AbstractAbout the AuthorReferences
At present, the tendency of improving physical-mechanical properties of building material due to the activation of raw components is observed. One of the methods is the activation of cement in the apparatus of vortex layer. The paper presents the data on optimization of parameters of the apparatus of vortex layer by means of realization of the four-factor plan of the second order for heavy-weight concrete of B25 class. On the basis of the experiment planning, optimal parameters of operation of the apparatus of vortex layer, sizes of ferromagnetic particles and relation of ferromagnetic particles to the material activated were revealed. The mathematical dependence of durability of heavy-weight concrete at the age of 1 and 28 days of hardening on the independent variables was found. At optimal conditions of the apparatus of vortex layer operation, improving the compression strength of heavy-weight concrete takes place at the first day of hardening by 2.44 times and at the grade age – by 1.48 times.
