Abstract

Magnesium oxysulfate (MOS) cement exhibits excellent adhesion and binding properties. It is lightweight, cheap and easy to use as well as has very good cementing properties compared to ordinary Portland cement. It is used in many types of aesthetic applications due to its white color, moreover, can be easily prepared by simply combining magnesia and a concentrated solution of Epsom salt. Gum arabic and silica gel G were used as additives with MOS to enhance water resistance and strength. The results showed that the incorporation of different amounts of gum arabic and silica gel G in MOS enhances the compressive strength of the modified product and lengthens setting times.The results showed that among all the compositions, MOS cement containing 5% additives (2.5% gum arabic and 2.5% silica gel G) significantly enhanced the long-term strength and water resistance of MOS cement.
