Abstract
The existing methods of non-autoclaved foamed concrete wall blocks production are analyzed. The advantages and disadvantages of each are considered. It is noted that the injection molding technology requires compliance with certain mode during the foamed concrete hardening and its further care. Moreover, products, obtained by injection molding technology have a higher degree of shrinkage and cracking, and lower strength. The main ways of the strength increasing of non-autoclaved foamed concrete, from the moment of mixture manufacturing, till foamed concrete hardening are studied. The most common way to improve the strength properties of the foam concrete is to use the strength enhancing additives, and additives that provide the dispersion rein-forcement. The main curing accelerators and plasticizers are given. The characteristics of the most common dispersion-reinforcing additives are considered.
