| Abstract: | Experiment was done to make a new-typed controlled low strength material(CLSM)with some industrial wastes including copper ore tailing,coal fly ash and gas-filling agent,and a portion of cement as well as water.The experiment resulted in an optimum formula,with which compressive strength of the CLSM could reach the range of 0.35~2.00MPa,the 28d compressive strength being 0.5mPa.The result suggested the new CLSM featuring more of low-intensity and high-mobility than the conventional filler used in civil engi... |
