Abstract

Maximal use of local natural substandard raw materials in the technology of repairing concrete and ferro-concrete structures determines the possibility of obtaining modified repair compositions with improved characteristics based on barkhan sands in order to restore the bearing capacity of products and structures and prolong their service life. The research determined the theoretical provisions for obtaining a modified compound with a comprehensive use of "Portland cement - barkhan sand - calcium sulfate dehydrate - C-3" binder and polymer components, with the help of which it is possible to adjust the hardening process and shrinkage deformation, increase adhesion, and reduce the total volume of capillary pores, which, as a result, increases the physicomechanical and operational properties of the proposed composites.
