通过正交试验研究了砂率、脱硫灰替代率、脱硫石膏替代率和微硅粉替代率四个因素对新型混凝土干表观密度、软化系数、导热系数、绝干抗压强度以及吸水率5个指标的影响。结果表明:各因素对新型混凝土5个试验指标的影响顺序为:脱硫石膏C>脱硫灰B>砂率A>微硅粉D。综合平衡分析各因素对新型混凝土5个试验指标的影响,确定了工业灰渣-陶粒新型混凝土的最优配合比。 Orthogonal test of the sand rate, the rate of substitution of desulfurization, the replacement rate of gypsum and the replacement rate of silica fume four factors on the new concrete dry apparent density, softening coefficient, thermal conductivity, absolute dry compressive strength and water absorption 5 The impact of a target. The results show that the order of influence of each factor on the five experimental indexes of new concrete is as follows: desulfurized gypsum C> desulfurized ash B> sand rate A> micro-silica powder D. Comprehensive balance analysis of the various factors on the new concrete test indicators 5 to determine the optimal combination of industrial ash - ceramsite concrete.
