Study on the performance of the soil stabilisation of peat soil using hydrated lime / Mustan Apo

Malaysia can be considered as a developing country. There are many mega projects had
been construct all over place in Malaysia. Sepang Circuit is the one of major project that
had been done on the problematic soil. In general, it is consists of an accumulative of
highly organic material. These are very compressible and entirely unsuitable for
supporting building foundation. This study, effect of lime on peat soil has been
investigated. Lime are prepared in two different mixture, lime powder and lime slurry.
The test has been repeated after the addition of lime-treated samples in different
proportions. Compressive stress under this two type of mixture is evaluated by
unconfined compressive stress test, and the performance of this admixture will be
compared. From the past research found that, the more content of lime the more
improvement on soil especially in physical and engineering properties. In this test, the
stabilization of soil samples conducted of three different proportions which are 3%, 6%
and 9%. The unconfined compressive stress is also increased with long curing period. In
these research three types of curing is considered there are immediate, 3 days cured and
7 days curing period. In this study, the value of California Bearing Ratio of soil treated
is also evaluated. Lime slurry as admixture for CBR test since it is more effective
compared to lime powder admixture. Sample prepared is similar with UCT test
preparation. It is found that the CBR value is increase with increasing lime percentage
and long time period.
