混凝土抗渗性能是衡量混凝土耐久性的重要指标。通过纤维素纤维混凝土的抗渗性能试验,研究了纤维掺量对C 50高强度混凝土抗渗性能的影响规律,分析了影响纤维素纤维混凝土渗透性能的主要因素。试验结果表明:纤维素纤维显著提高了混凝土的抗渗性能,随着纤维掺量的增加,混凝土渗透系数不断减小,抗渗性能逐渐提高,即使纤维素纤维掺量为0.9 kg/m3,也能使混凝土抗渗性能得到明显改善。
Impermeability of concrete is an important indicator of durability of concrete. Through the impermeability test of cellulose fiber reinforced concrete, the effect of fiber content on the impermeability of C 50 high strength concrete was studied. The main factors affecting the permeability of cellulose fiber concrete were analyzed. The test results show that the cellulose fiber significantly improves the impermeability of concrete. With the increase of fiber content, the permeability coefficient of concrete decreases continuously and the impermeability of concrete increases gradually. Even if the dosage of cellulose fiber is 0.9 kg / m3 Can make concrete impermeability can be significantly improved.
