Abstract Tailings known as solid waste are generated by the mining industry. The development of tailings as wet shotcrete
aggregates has significant economic and environmental benefits. The fine particle size of the tailings results in a
large consumption of traditional cement as a cementitious material and insignificant improvement in strength.
Therefore, a composite cementitious system of cement and solid waste resources (fly ash and slag powder) is
explored for this study. In this paper, the response surface methodology (RSM) is used to optimize the experimental design and a multivariate nonlinear response model with cement, fly ash and slag powder contents as… More >
