Soft soil was one of the most widely encountered problems in construction, especially for archipelago countries which its area lowland with a high deposit soft soil. To overcome this problem, stabilization used as solution. Soil general uses chemical substances that are classified pozzolan material. Pozzolan material capability to strengthen cohesion grains. Mostly, consists silica. Overboulder...

Bedrock unconfined compressive strength (UCS) is a key parameter in designing thegeosciences and building related projects comprising both the underground and surface rock structures. Determination of rock UCS using standard laboratory tests is a complicated, expensive, and time-consuming process, which requires fresh core specimens. However, preparing fresh cores is not always possible, especi...

Improvement and stabilization of soils are widely used to improve the physical and mechanical properties of sandy soils. Despite the abundance of researchers that have been conducted on this topic to date, most of them have focused on dry soil. The effects of the existing water in the soil and different curing durations (curing environment) have not been investigated. In this study, different p...

Soil is one of the common materials used in construction industry whether it for groundwork, infrastructure or as building materials. However, issues arise when structures are built on soft soil such clay that causes instability and settlement. In order to improve strength, various methods had been adopted by researchers use stabilizers like lime, cement fly ash. This paper presents improvement...
