摘要
通过三点弯曲试验研究分析了五种不同钢纤维体积掺量下活性粉末混凝土(RPC200)的抗弯初裂性能及其随纤维体积率的变化规律,并提出了活性粉末混凝土抗弯初裂性能的临界纤维体积率和最优纤维体积率。
The initial cracking performance of reactive powder concrete and its changing rule with five different volumetric fractions of steel fiber were studied in the paper by three-point bending test, The critical and best volumetric fraction of steel fiber in reactive powder concrete were also presented.
