摘 要:研究了不同体积掺量(0.1%、0.2%、0.3%)的玄武岩纤维和引气剂(0.03%、0.05%、0.08%)对混凝土抗冻性能和力学性能的影响。结果表明,混掺玄武岩纤维和引气剂可以提高混凝土的抗冻性,且最优掺量分别为0.2%和0.03%;相同纤维掺量时,随着引气剂掺量的增加,混凝土的力学性能降低;引气剂掺量不变时,掺入0.2%的玄武岩纤维对混凝土力学性能的提高效果最佳。
Abstract: The influence of different volume content (0.1%, 0.2%, 0.3%) of basalt fiber and air-entraining agent (0.03%, 0.05%, 0.08%) on the frost resistance and mechanical properties of concrete were studied. The results show that mixing basalt fiber and air-entraining agent can improve the frost resistance of concrete, and the optimal combination is 0.2% and 0.03% respectively. At the same fiber content, the increase of the amount of air-entraining agent can reduce the mechanical properties of concrete. With the same amount of air-entraining agent, the addition of 0.2% basalt fiber can best improve the mechanical properties of concrete.
