摘 要:通过响应面Box-Behnken实验设计,对玻化微珠增强秸秆灰/水泥复合材料的性能进行了优化研究。研究结果表明,所选模型具有显著性(P<0.05),模型优化得出的复合材料最优工艺参数为:掺入量为10%,粒径为600 μm。在最优工艺下,玻化微珠增强秸秆灰/水泥基复合材料的导热系数为0.291 9 W/(m·K),相比未优化处理的,导热系数降低了36%。
Abstract: Through response surface methods, the properties of glazed hollow bead reinforced straw ash/cement composites are optimized. The results show that the selected models are significant(P<0.05), and the optimal technological parameters are 10% of the blending amount and 600 μm the particle size. Under the condition above, the thermal conductivity of the glazed hollow beads to enhance the straw ash/cement-based composites is 0.291 9 W/(m·K), which is 36% lower than that of the unoptimized treatment.
