The results of experimental studies of mechanical properties of cement foam concrete with average density from 1200 to 1600 kg/m3 at different age and for different hardening conditions are presented. Concrete hardening took place in an unloaded state in laboratory conditions, under conditions of long-term load action and under conditions of natural physical-climatic actions, when the material was affected by degradation processes from humidification, drying, freezing–thawing, carbonization. The mechanical properties of foam concrete were determined according to standard test methods. It was found that during hardening in laboratory conditions in non-autoclave cement foam concrete there is a greater increase in strength and modulus of elasticity in time than during hardening in full-scale conditions, and the greater the lower the average density of concrete. The effect of strengthening foam concrete under the influence of a long-term applied load with respect to the same concrete, which was in the same temperature and humidity conditions, but without the load, was revealed.
