Abstract A study has been conducted to investigate the mechanical behaviour of cement-treated sand under compression and tension. Cylindrical and notched beam specimens were made by using high early strength cement, sand, and limestone powder with varying ratios of water to cement ( W / C ), specific ratios of cement to sand ( C / S ), and limestone powder to cement ( L / C ). The influences of the material strength and height to diameter ratio ( H / D ) on the compressive and tensile strength, as well as the fracture energy were investigated. Stress strain relationships are proposed to predict the behaviour of cement-treated sands.
