Chemical stabilization of amorphous peat via cement and fly ash with lime

Organic soil such as peat is a very problematic soil and poor in strength. However previous researches have proved that the compressive strength of peat can be improved by using various method of soil improvement including chemical stabilization method. Due to that, the aim of this study is to improve the compressive strength of amorphous peat, various water to additive ratio were used to obtain the optimum Unconfined Compressive Strength (UCS) value. In this study, peat samples were collected in Jalan Kampung Meranek, Samarahan and mixed at its natural moisture contents with cement and fly ash plus lime at different water additive ratios of 3.0 and 3.5. The compressive strength of the sample was obtained by Unconfined Compressive Strength Test (UCS) and analyzed
