THE STUDY OF THE INTERACTION OF ADHESIVE WITH THE SUBSTRATE SURFACE IN A NEW COMPOSITE MATERIAL BASED ON MODIFIED GYPSUM AND TREATED RICE STRAW

Abstract

The article considers the issues of thermochemical treatment of the surface of plant aggregates to ensure strong adhesive interaction with a gypsum matrix in a composite building material. A selection of additives contributing to the improvement of adhesive strength and physical and mechanical properties of gypsum boards was conducted. A comparative analysis of the effect of moisture sorption on the durability of the composite material at the processing of fiber aggregates was also performed.
