玄武岩纤维地质聚合物在软土固化中的力学性能试验研究OA
Experimental Study on Mechanical Properties of Basalt Fiber Geopolymer in Soft Soil Solidification
为了解决水泥在寒冷地区加固天然土壤强度不足、脆性大等问题,制备了一种纤维基地质聚合物,用于软土和道路路基的加固.通过无侧限抗压、抗拉和剪切试验,同时结合SEM微观表征手段,对比分析了不同土壤体系的力学性能,揭示了纤维基地质聚合物微观加固机理.研究结果表明:碱激发粘合剂的含量为13％时,地质聚合物稳定土体系抗压强度值为725 kPa;纤维掺量0.6％、长度4 mm时,纤维基地质聚合物体系的力学性能达到最佳;不同土壤体系的抗拉和抗剪强度有所差异,其中…查看全部>>
In order to solve the problems of insufficient strength and high brittleness of natural soil reinforcement by cement in cold regions,a fiber geopolymer was prepared for the reinforcement of soft soil and subgrade.Through un-confined compression,tensile and shear tests,the mechanical properties of different soil systems were compared and analyzed to revealing the microscopic reinforcement mechanism of fiber geopolymer by SEM microscopic char-acterization meth…查看全部>>
