SOFT BANGKOK CLAY STABILIZED WITH CEMENT AND BAGASSE ASH
Keywords:
Bagasse ash, soil improvement, unconfined compressive strength, water-to- binderAbstract
The main objective of this study is to assess the effectiveness of bagasse ash (BA), a type of agricultural waste from the sugar industry, as an admixture to improve the unconfined compressive strength, chemical composition, and microstructural properties of soft clay. Ordinary Portland cement (OPC) type I is partially replaced by BA and mixed with soft clay to generate cement bagasse ash-admixed soft clay. The test results show that the replacement of OPC with BA can enhance the strength by as much as that of OPC alone, and 20% BA is considered the optimum. The correlation between the modulus of elasticity and the unconfined compressive strength can be expressed as a linear function. The strength development with curing time can be represented using an exponential function.
