The influence of lime on the swelling and strength characteristics of soil in Telkef district near mosul.

This study aims to investigate lime stabilization of medium plasticity clay. Typical samples of soil with different amounts of lime (0%, 1%, 2%, 3%, 4% and 5%) by weight were prepared and tested in free swell, constant volume and unconfined compression tests. The results showed that adding (2%) lime by weight to the soil eliminates about (75%) of its swelling pressure and reduces its swelling potential by about (95%). The compressive strength of the original soil was also improved by about (7.5 times) at (2% lime content and 7 days curing time). [ABSTRACT FROM AUTHOR]
