Control factors for the long term compressive strength of lime treated sandy clay soil

This study aims to quantify the effect of curing time, lime content, dry unit weight, and compaction water content on the strength of a lime treated sandy clay, as well as to evaluate the use of the porosity/lime ratio to assess its unconfined compressive strength. The results showed that compressive strength increased with increasing lime content, decreasing porosity, and increasing curing time. It was shown that the porosity/lime ratio is a good parameter for the evaluation of unconfined compressive strength and a unique relationship was achieved linking unconfined compressive strength with both porosity/lime ratio and curing time.
