为合理利用废弃材料改善生土材料力学性能,通过在素土中掺入糯米浆、废玻璃渣和橡胶,形成改性土体材料,设计5种配合比方案,制作Φ102 mm×116 mm圆柱体试块。通过对其进行轴心抗压强度试验,对比不同配比试件的试验现象、抗压强度、变形能力、荷载位移曲线,分析不同掺合料的作用机理、研究不同掺料不同掺量对抗压强度的影响规律,提出了玻璃渣和橡胶掺量的合理范围。试验结果表明,在素土中掺入糯米浆能提高素土抗压强度,掺入糯米浆、玻璃渣和橡胶,可提高抗压强度和变形能力,但其抗压强度随玻璃渣和橡胶掺量的增多增至3.12 MPa后下降。
In order to improve the mechanical properties of raw soil materials by using waste materials rationally, five kinds of compounding schemes were designed by adding glutinous rice slurry, waste glass slag and rubber into plain soil to form modified soil materials, and the Φ102 mm × 116 mm cylinders Test block. Through the axial compressive strength test, the test phenomena, compressive strength, deformation capacity and load-displacement curve of different proportioning specimens were compared and the mechanism of action of different admixtures was analyzed. Strength of the law, proposed a reasonable range of glass slag and rubber content. The results showed that the incorporation of glutinous rice slurry in plain soil can improve the compressive strength of plain soil. The incorporation of glutinous rice slurry, glass slag and rubber can improve the compressive strength and deformation capacity, but the compressive strength increases with the glass slag and rubber The amount of increase increased to 3.12 MPa after the decline.
