High-Void Non-Autoclaved Silicate Composites with Aluminosilicate Raw Materials

Abstract

Today, silicate wall materials are widespread among the applied wall materials in construction. Their traditional production technology involves the use of cementing component, obtained by the mixed grinding of unhydrated lime and silica materials. Nowadays, one of the main tasks is to reduce the production energy intensity of variously-functional wall composites through the use of unconventional, including manmad, raw materials. From this perspective, non-traditional for the construction industry clay rocks of the unfinished minerogenesis stage, are of particular interest. To stabilize clay rocks, complex methods can be used, in which, as a rule, several additives are used, which effect on the rock can be different. It has been established that the use of aluminosilicate binder, including lime (Portland cement) for the production of non-autoclaved silicate wall materials based on non-traditional clay rocks, will contribute to achieving the necessary level of structure formation and maximum physical and mechanical properties of high-performance highvoid wall products under non-autoclaved conditions.
