ВПЛИВ УМОВ ТВЕРДНЕННЯ НА КІНЕТИКУ НАБОРУ МІЦНОСТІ ЛУЖНИХ БЕТОНІВ З ВИКОРИСТАННЯМ АКТИВНОГО ЗАПОВНЮВАЧА

Abstract

The main problem with the use of active aggregates is the occurrence of alkaline corrosion during the curing of the material,
due to which it is destroyed and can no longer be restored. That is why when solving the issue of alkaline corrosion it is necessary to look for ways to completely prevent or reduce the rate of development, rather than possible ways to eliminate the consequences. The article describes the raw materials that were used during the tests and the methodology of their conduct. The results of research aimed at determining the influence of component composition and curing conditions on the kinetics of strength set of materials based on alkaline cements, where basalt sand was used as a aggregates, are shown. The key factors influencing the strength of the hardened material are presented and the best curing conditions for the elimination of destructive processes in the concrete body are determined.
