Experimental Study on Producing Concrete Hollow Block with Mining Slag

Abstract

The experiments of compressive strength about maix proportion of concrete are repeatedly done, adopting orthogonal experimental method. In this experiment, dry separation waste rocks and mine tailings in mining slag of Qidashan Iron Mine which is subsidiary company of Anshan Iron and Steel Corporation are used instead of traditional fine and coarse aggregate concretes. Then the optimized mix proportion is determined to make the concrete small hollow blocks. Sample test shows that it is feasible to make load bearing concrete small hollow blocks which can meet national standards.
