This paper presents the role of clay portion in soil used to stabilize soils during alkaline activation with potassium-based alkaline activator. A 10 M potassium hydroxide solution was utilized to activate the soils with and without palm oil fuel ash (POFA) at a solution. Soils with and without POFA mixtures were tested using unconfined compression tests and microstructural analysis (using scanning...
This work presents the effect of lime and treated coir fibre on the mechanical behaviour of soft clay soil as a pile-supported earth platform. The experimental programme comprised three types of test (flexural strength, indirect tensile strength and triaxial compression strength). Experimental results were used in a numerical analysis in order to observe the performance of the treated soil as a load-transfer...
The purpose of this study is mainly to investigate the tensile and compression strengths of natural and treated soft soil. The tensile strengths and compression strengths of compacted specimens of natural soil, lime and coir fiber treated soil were obtained using the indirect tensile test and unconfined compressive test. The results revealed that both tensile and compressive strengths increased with...
A group of lithologies which includes claystone, siltstone, mudstone and shale also known as mudrocks are indurated sediments widely encountered throughout the world. Shear strength and deformation characteristics of mudstone were investigated using a fully automated hydraulic stress path testing system under three rock states: dry, short-term inundated, and long-term. It is observed that the maximum...
