We have studied mortality patterns in a large cohort of rubber workers. We have examined workers exposed to curing fumes, processing dusts, and industrial talc and have begun to evaluate exposures of these workers in detail. Gastrointestinal (especially stomach) cancer appears in excess in processing workers. Lung cancer is excessive in curing workers. Leukemia is increased generally. All three...

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...
