Вплив структурних характеристик на стійкість бетону до динамічних впливів

Abstract

The article deals with theoretical and experimental research into dependency of crack resistance of concrete under dynamic effects on coefficients of grain separation of coarse and fine aggregates. It was established that these dependencies were of extreme nature. The research yielded the optimal values of coefficients of grain separation of coarse and fine aggregates, cement particles, and also water-to-cement ratio for the materials under study; these factors provided the best physical and mechanical properties of concrete, including its crack resistance under dynamic effects, both impacts and vibrations.
