Abstract

This paper describes the strength-deformation characteristics and internal structures of cement-stabilized soils mixed with bassanite and coal ash. The unconfined compressive strength of cement-stabilized soil with coal ash increases with increasing bassanite addition ratio. Based on the observation of internal structure using a scanning electron microscope (SEM), ettringite occurrence is related to the strength increase of cement-stabilized soil. Well-developed ettringite could be seen in the case of higher bassanite and higher coal ash addition ratios.
