Contaminated land sites are increasingly being redeveloped for housing, industrial, commercial and leisure use. The potential risks from contamination in the ground extend from human health to damage to buildings. BRE has been undertaking a research project to assess the potential for contaminants in the ground to attack concrete. This paper reports the results of concrete cubes that have been immersed in solutions of contaminants for three years. The results suggest that some concrete mixes are likely to be degraded to a greater extent by the mixture of contaminants as opposed to sulfate acting on its own. However, mixes that are recognised as being resistant to contaminant attack have performed well to three years. In addition, beneficial effects of a water-reducing admixture used with a Portland cement concrete have been found.
