2019年8月21日 The factors affecting particle crushing were investigated. The results showed that the optimum water content of the slag–clay mixture decreases, whereas the maximum dry density increases first and then decreases, as the slag content increases. The optimum slag content of slag–clay mixtures is 30% despite different initial gradations.
