Effect of CaSO4 on hydration and phase conversion of calcium …

10/11/2019· Abstract. Conversion from metastable phase to stable phase in calcium aluminate cement (CAC) causes volumetric instability, resulting in loss of compressive strength. This study investigated the effect of CaSO 4 on the phase conversion of calcium aluminate cement. The specimens with different dosage of CaSO 4 were exposed to 60 °C to trigger

Mineral additions can eliminate the conversion in calcium aluminate hydrates and thus inhibit the future strength retraction of calcium aluminate cement (CAC). However, the impacts of these additions on the protection capacity of CAC concrete in relation to the corrosion of eedded steel reinforcement remains unclear. This paper focused on the corrosion behavior of steel reinforcement in slag
