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 the replacement of crushed coarse aggregate in the amount of 10 vol.% with ground rubber from used car tires increases the bending strength by 23% The compressive strength does not change significantly.

When working in the subcritical stage of deformation (until the macrocrack shifts), concrete with the replacement of the coarse aggregate is preferred, as the energy consumption of which for elastic deformation (We) exceeds the base concrete.

Analysis of the supercritical stage of deformation (macrocrack propagation) reveals that the replacement of fine and coarse aggregates negatively affects the value of total energy consumption for local static deformation in the main crack zone (Wl), which is by 1.35 and 1.14 times lower than the control concrete.
