Effect of soapstone powder on cementing properties of magnesium oxysulfate cement

Magnesium oxysulfate cement is a type of Sorel’s cement and it does not require any type of energy whether heat or light, making it an eco-friendly binding substance. Non- hydraulic Magnesium oxysulfate cement has many superior properties to that of ordinary Portland cement. Magnesium oxysulfate cement draws much research interest due to energy saving and environmental protection consideration. In spite of a variety of advantages, its commercial use is limited due to its low early strength and poor water resistance. In this study, the effect of soapstone powder on setting times, weathering effect, compressive strength, moisture ingress, and linear changes has been comprehensively investigated. The results show that strength and water resistance increases while setting time decreases by adding soapstone powder in different percentages.
