玄武岩纤维水泥土无侧限抗压强度的研究

Experimental study on compressive strength of basalt fiber cement soil

文中对玄武岩纤维加筋水泥土的无侧限抗压强度进行了研究。在水泥掺量、水灰比一定的基础上,研究了不同的玄武岩纤维掺量对水泥土无侧限抗压强度的影响。研究结果表明,玄武岩纤维的掺量对水泥土的抗压强度有显著的提升作用,但其增幅会随着掺量的增加而有所减缓;随着养护龄期的增长,水泥土的抗压强度也随之增大;玄武岩纤维的掺入提高了水泥土的韧性和整体稳定性。

The unconfined compressive strength of basalt fiber reinforced cement soil is studied in this paper.Based on the certain content of cement and water-cement ratio,the effects of different contents of basalt fiber on the unconfined compressive strength of cement soil were investigated.It is found that the content of basalt fiber will obviously improve strength of cement soil,but its increase will slow down with the increase of the content;The cement-soil samples without basalt fiber show brittle failure,and the cement-soil samples with basalt fiber show plastic failure,so the incorporation of basalt fiber also improves the toughness and overall stability of the cement soil.
