Review article

The article presents the study results analyzing the influence of the cement stone age at the moment of its early loading on the change in strength at bending and compression in comparison with the unloaded cement stone. As a binder, aluminum alumina cements with variable content of Al2O3 are used. Experimental data have shown an increase in the tensile strength at bending in loaded samples, and the resulting graphs have shown a decrease in its value with increasing age. Regression equations «age of samples at the moment of loading - the increase in strength at compression and bending» are given, and the hypothesis of their adequacy has been checked.
