Abstract: Controlled low strength material (CLSM) is designed to serve as a flowable material for filling purposes. It is made with small amounts of cement and produced with conventional concrete technology. To achieve high fluidity it is made with large amounts of water that may lead to significant volume changes during service.
In this study CLSM made from waste materials was studied. The wastes were dust from cement kiln, asphalt plants and coal fly ash, and coarse sand from quarry waste and bottom ash from coal power plants. The results indicate a significant effect of the fineness, shape, surface structure and relative content of the waste on the volume changes, both at early age and later ages.
