摘 要:将玄武岩纤维作为外掺材料掺入水泥固化风积砂中,对不同水泥掺量及玄武岩纤维掺量的水泥固化风积砂进行无侧限抗压强度试验研究。结果表明,在水泥固化风积砂中掺入玄武岩纤维后,玄武岩纤维可在水泥固化风积砂中均匀分布,形成一种良好的相互交错的支撑体系;掺入玄武岩纤维可以提高试件强度,且在纤维含量为0.5%时试件的抗压强度最大;随着水泥掺量的增加和龄期的增长,掺纤维水泥固化风积砂的抗压强度逐渐增加。
Abstract: Using basalt fiber as a additive mixture with cement solidified aeowan sand, the experiment on unconfined compressive strength of solidified aeowan sand with different dosages of cement and basalt fiber is carried out. The results show that after adding basalt fibers into the cement solidified aeowan sand, basalt fibers are evenly distributed in the cement solidified aeowan sand, developing a kind of interrelated supporting system; the compressive strength could be enhanced as the contribution of adding basalt fibers and the compressive strength rise to the peak when the dosage of basalt fibers is 0.5%; along with the increasing of the dosage of cement and age, the compressive strength is gradually increasing.
