Research in Influence of Regimes of Forced Carbonate Hardening on Properties of Materials on the Basis of Lime-Limestone Compositions of Semidry Pressing
Results of the research in forming properties of lime-limestone compositions of semidry pressing depending on the regimes of forced carbonation and prescription-technological factorsof their production are presented. The research was conducted with the help of experimental-statistical models by the method of mathematical planning of experiments with the use of arotatable 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 samplesof lime-limestone 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 methodswith 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 hardeningof 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 processin a static regime at moderate (up to 50%) concentrations of СО2.
