Results of the research in forming properties of limelimestone compositions of semidry pressing depending on the regimes of forced carbonation and prescriptiontechnological factors of their production are presented. The research was conducted with the help of experimentalstatistical models by the method of mathematical planning of experiments with the use of a rotatable central composition plan. The influence of dynamic and static regimes of the forced carbonation on the formation of compression strength and water resistance of the samples of limelimestone compositions of semidry pressing is considered. It is shown that the use of more intensive methods of forced carbonation is less efficient than the use of methods with moderate supply of СО2 in the carbonizing chamber in the process of its absorption by samples. The most reasonable method of organization of accelerated carbonate hardening of the systems on the basis of lime can be a combined method which is to create a preliminary vacuum in the carbonizing chamber with the further organization of the process in a static regime at moderate (up to 50%) concentrations of СО2.
