摘　　要：选取合适的地方材料，采用改进的全计算法进行自密实混凝土配合比的计算，通过试配配制出C30自密实混凝土。掺入不同长度、不同掺量的聚丙烯腈纤维，研究其对C30自密实混凝土早期抗裂性的影响规律。试验结果表明，掺入聚丙烯腈纤维可显著提高自密实混凝土的早期抗裂性。Appropriate local materials are selected, mix ratio of self-compacting concrete is calculated by using the modified overall calculation method, and the C30 self-compacting concrete is confected through trial mix in the experiment. And then the influence of earty crack resistance of C30 self-compacting concrete is researched by mixing with polyacrylonitrile fiber in different length and proportion. The experimental results show that the polyacrylonitrile fiber can significantly improve the early crack resistance of self-compacting concrete.
