The optimum reaction conditions were obtained by orthogonal experiments. When the mass ratio of sodium polyacrylate to inorganic substances is 1:1.5:1.5,and the dosage was 0.3%,it got the best water reduc- ing rate 58.75 %.Experimental results showed that the composite deflocculant had good water reducing property in the ceram...
