摘要
为研究RPC各组分与其抗冻性能之间的关系,通过设计正交试验,探讨了水胶比、硅灰水泥比、钢纤维掺量等因素对普通混凝土和活性粉末混凝土冻融性能的影响。研究指出,在RPC抗冻性的诸多影响因素中,水胶比是最主要的影响因素,其次是硅灰水泥比,最后是钢纤维掺量。
In order to research the relationship between the each RPC component and the anti-freezing performance, it accords to the designing of the orthogonal experiment, talks about the influences of the factors （such as water-binder ratio, silica fume cement ratio, steel fiber mixing amount） for the common and reactive powder concretes freeze-thaw performances. It points that water-binder ratio is the main factor in the influencing factors of the RPC anti-freezing performance, the second factor is silica fume cement ratio, and the last is steel fiber mixing amount.
