Abstract

The unsaturated polyester resin concretes using the aluminum dross wastes as aggregate were prepared and their mechanical properties and water resistance were examined. Four types of dross wastes were used; the waste pre-treated with water, the non-treated waste, the dust waste and the chloric waste. When the mixing between the resin and the waste was satisfactorily achieved, the resin concretes with the strength and the water resistance equal to or above the commercially available products could be obtained. The aluminum-nitride contained in the waste is seemed to contribute to strengthening of the resin concrete owing to the formation of aluminum hydroperoxide acting as an initiator of polymerization, although an excessive content damages the water resistance. The dust waste could be also used to prepare a resin concrete, but the chloric waste could not be used.
