Study on the Mechanical Performance of Soft Sandy Soil Solidified by Epoxy Composites

Article Preview

Abstract:

In this work, we propose the stabilization of soft sea sand by an epoxy composite solidifier, which can be extremely beneficial in the fields of national defense, rescue engineering, and traffic emergency support under complex conditions. The effects of material ratio, curing time, curing temperature, and moisture content on the mechanical performance (compressive strength, bending strength, and splitting tensile strength) of solidified sea sand are investigated by indoor tests. The results indicate that the epoxy composite solidifier can rapidly enhance the mechanical performance of sea sand, thereby improving the beach trafficability and facilitating traffic emergency support. The strength of solidified sandy soil increases with the increase in curing time and temperature or with the decrease in moisture content. Furthermore, the epoxy composite solidifier exhibits good solidification capability under low temperatures and saturated moisture content. Keywords: epoxy resin; solidifier; sea sand; mechanical test
