Study links deterioration of concrete and asphalt to trace quantities of organic matter; diesel exhaust, windshield washer fluids

Green Car Congress

During their experiments, the scientists happened to notice that a strange odor developed when commercial cement was mixed with water. Of the organic matter present in cement, phthalates have the highest effect on deterioration more than phosphates and AE water reducing agents. CT scans showing cracks in damaged concrete.
