Hyper-Pressed Composites from Recycling Products of Aerated Concrete Waste

Abstract:

A technology has been developed for obtaining wall materials by the hyper-pressing method, including the recycling of large-tonnage waste from the production of autoclaved aerated concrete. The main component of the raw mixture is finely ground filler fractions, obtained by crushing substandard fragments of aerated concrete. The joint influence of raw mixture, the parameters of pressing and the conditions of hardening on the indicators of material properties has been investigated. There was given a quantitative assessment of the individual components contribution of the raw material composition to the indicators of the physical and mechanical properties of the material. The mechanism is disclosed of the constructive effect of aerated concrete recycling waste and plasticizing additives on the water resistance and strength of samples. The promising areas of application of hyper-pressed materials in modern construction are presented.
