Resumo

The article presents the results of the study of biostability of gypsum-foam-glass concrete (GFGC) – a promising composite material based on modified gypsum binder (MGB) and granulated foam-glass. The relevance of the work is conditioned by the necessity to create construction materials resistant to bio-damage under unfavorable environmental conditions without the use of biocidal additives. It has been experimentally proved that GPSB has high biostability (2 points according to GOST 9.048–89 against 5 points of traditional gypsum stone), which is conditioned, first of all, by the shift of pH in the alkaline region, and secondly, by the reduction of water absorption, reduction of open porosity, formation of hydrosilicate phases, strengthening of the contact zone. The obtained results confirm the promising application of GFGC in structures operating in atmospheric conditions with increased humidity due to its increased water resistance and bio-resistance, which indicates increased durability and operational reliability of structures made of GFGC.
