Experimental Assessment of Nano-Effects in Foam Concrete Technology

The scientific substantiation of the influence of the mixing speed of raw materials on the amount of capillary coupling forces between dispersed particles of the solid phase in foam concrete mixtures is given. It is shown that the intensity of external energy impact on raw materials controls the mass transfer features when manufacturing foam concrete mixtures and, as a result, the ratio between the amount of surfactants at the gas–liquid interface and in the interpore space. It is proved that the fiber from synthetic fibers, due to the size of its surface energy potential and shape, is able to control the speed of mass transfer of raw materials at an early stage of the formation of the structure of foam concretes. It is experimentally established that increasing the speed of mass transfer at the nanoscale, that is, during the predominance of weak energy interactions between raw materials components, positively affects the kinetics of plastic strength in foam concrete mixtures and the mechanical properties of the hardened material.
