Description
Summary:Soft and expansive clay is a soil type mostly found in Indonesia. Cement addition is one of the treatments common applied in soft clay improvement. However, its utilization requires to be controlled considering the effect to environment. Bamboo is a very abundant natural resource. On the other hand, bamboo leaf still requires attention in terms of management and utilization. In the form of ash, bamboo leaf contains high silica that could be used as pozzolan material. This research investigated the effect BLAsh addition in reducing cement utilization to the CBR value parameter of soft clay soil by experimental analysis. The total content of stabilizer material in the soft clay soil is 12% of the dry soil mass. Then, BLAsh content was varied in 0%, 25%, 50%, 75%, and 100% of the total content of stabilizer material. The result depicted that 25% of cement substitution by BLAsh proved the improvement of CBR value both in dry and critical condition. In addition, improvement of expansive soil was proven by the decreasing of swelling percentage in the mixture with 25% of BLAsh content. Also, the longer curing time is important in providing perfect reaction of the chemical contents in the mixture.
