摘　　要：依据粉煤灰混凝土空心砌块的设计要求,设计粉煤灰夹芯砌块块型。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芯砌块。根据正交实验方法,研究了砌块的干缩性,发现砌块干缩性较好,值得推广应用。The block-type of the nano-fly sandwich block was designed in accordance with the requirements of fly ash concrete hollow block.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. Through methods of orthogonal experimental, block＇s drying shrinkage was studied. The drying shrinkage of the block is better, and it should be widely applied.
