基于Autoclam渗透测试的玄武岩纤维高性能混凝土抗渗性能研究

Experimental study of the impermeability of basalt fiber high performance concrete based on Autoclam test

通过使用Autoclam渗透性测试仪对掺加了玄武岩纤维的高性能混凝土的透气性、吸水性和透水性进行了测定,分析了粉煤灰掺量和玄武岩纤维掺量对高性能混凝土抗渗性能的影响。研究结果表明,综合考虑Autoclam渗透测试系统的3个评价标准,在本文研究范围内,有利于混凝土抗渗性能的最优粉煤灰掺量为20%、最优玄武岩纤维掺量为1.2 kg/m3。

The Autoclam tester was used to measure the air permeability, hydroscopicity and water permeability of the high performance concrete mixed with basalt fiber. The effect of the content of fly ash and basalt fiber on the impermeability of high performance concrete was analyzed. The results show that the addition of 20% fly ash and 1.2 kg/m3 basalt fiber work most effectively in strengthening the impermeability of concrete based on the three assessment indexes of Autoclam permeability test system.
