水泥与EPS颗粒掺入比对LSES力学特性的影响

Influence of Mixed Ratio of Expanded Polystyrene and Cement on Mechanical Properties of Lightweight Sand-EPS Beads Soil

为研究发泡聚苯乙烯(EPS)颗粒掺入比与水泥掺入比对砂土与EPS颗粒混合轻质土(LSES)力学特性的影响,针对LSES做了无侧限抗压强度试验,获得了在不同水泥掺入比、EPS颗粒掺入比条件下,LSES的应力应变曲线、抗压强度及变形模量的变化规律。

To study the influence of the expanded polystyrene（EPS） mixed ratio and cement mixed ratio on mechanical properties of lightweight Sand-EPS beads soil（LSES）,the unconfined compression test is implemented for LSES.It obtains the collectivity change laws of stress-strain relation curves,compression strength and deformation modulus in different cement and EPS mixed ratios.
