Abstract
Currently, <a large amount of municipal solid wastes including domestic wastes are finally dumped and therefor the rate of recycling is not/high. Technology for the production of melting slag is being developed to assist in the recycling of these wastes. Melting slag is made from municipal solid wastes by high temperature processing, melting, and solidifying. If recycled concrete aggregate produced by the demolition of concrete structures and the melting slag may be mixed and used for RC structures, recycling both industrial and municipal solid wastes together will contribute to the reduction of the final disposal of wastes. This report conducted experiments with recycled concrete, which were made of recycled coarse aggregate and fine aggregate using melting slag, and investigated whether it could be used for RC structures in terms of the seismic performance. Experiments were conducted to examine the flexural, shear, and bond failures of RC beam members. As a result, the RC beam members of recycled concrete with melting slag showed the same seismic performance as that of ordinary concrete. This indicated that recycled concrete with melting slag could be used for RC structures in terms of the seismic performance.
