摘要：
This study was carried out to examine the application of sewage sludge molten slag as coarse aggregate for concrete and the influence of the quality of molten slag on the mechanical properties of concrete. As a result, it was clarified that the mechanical properties of concrete by using molten slag coarse aggregate depended on the quality of molten slag. The concrete by using molten slag coarse aggregate which was good strength had performance equivalent to normal aggregate concrete. In the quality standard of molten slag for concrete, it is necessary to provide not only the density and water absorption but also the standard related to the strength of aggregate. © 2011 The Society of Materials Science, Japan.
