RESEARCH ON ANTI-CRACKING PROPERTY OF CEMENT STABILIZED SOIL BLENDED WITH SYNTHETIC FIBER
-
摘要: 为提高道路半刚性基层的抗裂性,以合成纤维半刚性材料为研究对象,通过室内抗弯拉试验,分析合成纤维的掺量及试件养护龄期等对合成纤维水泥稳定土抗弯拉强度的影响。结果表明,随着纤维掺量的增加、长径比的增大,水泥稳定土的抗裂性亦逐渐增强;合成纤维水泥稳定土的抗裂性随着养护龄期的增长逐渐增大。Abstract: In order to improve anti-cracking of semi-rigid substrate, taking synthetic fiber as research object throughindoor bending and tensile test, the effect of fiber dosage and curing period of specimens on bending and tensilestrength of cement stabilized soil was analyzed．The study results indicate that with the increase of fiber contents andthe length-diameter ratio, the anti-cracking of cement stabilized soil was gradually strengthened; and was alsoincreased gradually with the increase of curing period．
