The dynamically developing construction in the Russian Federation makes it necessary to expand the range of alternative types of binders and materials based on them. Such a binder is a previously developed compo-site gypsum binder (CGB), used for the production of materials of various functional purposes.
The manufacture and use of CGB-based composites was made possible by studying the Portland cement-gypsum-water system, the stability of which is ensured by introducing an appropriate amount of active mineral additives that reduce the concentration of Ca(OH) 2 in the liquid phase of the hardening system and create the possibility of hardening under certain conditions without dangerous internal stresses. In this paper, we consider the possibility of using composite gypsum binder for fine-milled quartzitic sandstone crushing dropout and concrete scrap crushing dropout as an active mineral additive. Rational compositions of composite gypsum binder are developed and their basic properties are studied. The reasonable choice of the amount of active mineral additive allows optimizing the properties of the composite gypsum binder.
