Stabilization of Soft Bangkok Clay Using Portland Cement and Calcium Sulfoaluminate-Belite Cement

Abstract:

The present study investigates the mechanical properties of soft Bangkok clay which was stabilized by ordinary Portland cement and calcium sulfoaluminate-belite (CSAB) cement. The CSAB cement was synthesized by using several types of industrial waste materials such as marble dust waste and flue gas desulfurization gypsum. The raw materials were mixed in designed proportion and calcined at 1,250 °C for 2 hours. The X-ray diffraction patterns suggested the clinker consists of ~58% of ye'elimite and ~35% of belite. The slurry soft Bangkok clay with liquidity index of 1.0, 1.3 and 1.5 was stabilized with ordinary Portland cement and CSAB cement in the range of 5 - 20%. Based on the laboratory study, mechanism of rising unconfined compressive strength results which soft clay stabilized with CSAB cement could observe from Scanning Electron Microscope images.
