【摘要】 利用纳米材料、水泥、粉煤灰等主要原材料,加入适量外加剂,中间填入废弃聚苯乙烯泡沫,研制了纳米粉煤灰夹心砌块,研究了不同类型砌块的传热系数并进行了统计分析,发现纳米粉煤灰夹心砌块传热系数较低,保温性能较好。更多还原

【Abstract】 By using the nano-materials,cement,fly ash and other major raw materials,adding proper admixtures,and filling the waste polystyrene in the middle of the block,the nano-fly sandwich block was developed.The heat transfer coefficient of different types of block was studied and the statistical analysis was conducted.The nano-fly sandwich block was found to have the lowest transfer coefficient and the best insulation properties.更多还原
