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。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.
