Influences of carbonation on heavy metal diffusivity in cement hydrates

K. Kawai, T. Sato & Y. Miyamoto

ABSTRACT: Many studies on effective utilization of industrial by-products such as blast furnace slag and fly ash have been carried out. There is a possibility of heavy metal leaching from concrete containing wastes. In order to promote the use of wastes as a concrete material, the environmental impact of concrete containing heavy metals must be appropriately evaluated.
