摘要
主要研究聚丙烯纤维、粉煤灰等因素对混凝土的抗裂性的影响,得出了混凝土劈裂强度与纤维掺量、纤维长度的拟合公式,并提出了粉煤灰的最佳掺量,为聚丙烯纤维混凝土在工程中的推广应用提供技术指导。
This article mainly studied the influence of polypropylen textile fiber and pulverized coal ash to the concretes crack resistance,obtained the fitting formula about concrete’s cleavage strength and proportion、length of textile fiber,and proposed the best proportion of pulverized coal ash.These conclusions provide the technical guidance for the polypropylene textile fiber concrete in promoted application.
