Impact of curing and testing methodologies on the compressive strength of cement-stabilized soil

摘要

Cement-stabilized soil is generally used at shallow ground depths. For this reason, the pressure curing of specimens is not seen as an important part of the laboratory testing process. When cement-stabilized soil is used deep in the ground, however, an accurate appraisal of the compressive strength at the original depth is vital for the subsequent design and construction processes.This study has evaluated the impact of curing and test methodologies on the compressive strength of cement-stabilized soil. Battery of tests on cement-stabilized soil under pressure curing conditions has been conducted. And it is clarified that when using laboratory tests to determine the compressive strength of cement-stabilized soil at deep original positions, it is important to maintain the pressure after the pressure curing.
