摘　　要：根据商品混凝土特性,通过板式混凝土早期抗裂试验,研究了不同掺量下粉煤灰对商品混凝土早期开裂性能的影响。试验结果表明,不同掺量下的粉煤灰对商品混凝土均起到了限裂的作用,试验中各组混凝土的抗裂能力大小为FA-10>FB-12.5>FC-15>FD-30>FO-0。Based on the characteristics of commercial concrete,influence of different quantity of fly ash on early anti-cracking properties of commercial concrete is studied by the early anti-cracking test of plate concrete and commercial concrete plate constrained test.The results show that different quantity of fly ash play an important role in anti-cracking of commercial concrete,and the anti-cracking properties of each group in test arranges in order of size is： FA-10,FB-12.5,FC-15,FD-30,FO-0.
