MECHANICAL PROPERTIES OF CEMENT CONCRETES INCORPORATING GROUND TIRE RUBBER

This article proves the possibility of replacing aggregates in concrete mixtures with rubber, which is obtained by grinding used car tires. It was found that replacement crushed coarse aggregate amount 10 vol.% ground rubber from tires increases bending strength 23% The compressive does not change significantly. When working subcritical stage deformation (until macrocrack shifts), preferred, as energy consumption for elastic (We) exceeds base concrete. Analysis supercritical (macrocrack propagation) reveals fine and negatively affects value total local static main crack zone (Wl), 1.35 1.14 times lower than control
