- Synopsis:
- The melting treatment of the illegally dumped industrial waste and polluted soil in Teshima Island, Kagawa, has begun in Naoshima Island. At present, the molten slag is being used in precast concrete products and non-reinforced concrete structures as a fine aggregate. This paper describes flexural behaviour of reinforced concrete beams using the Teshima molten slag. The experimental results showed that load carrying behaviour of reinforced concrete beams using the molten slag can be evaluated by conventional methods and the crack widths of reinforced concrete beams are influenced by the presence of molten slag and the compressive strength of concrete.
