Abstract

This study aims to investigate the influence of molar ratio variation on the compressive strength of stone-incorporated magnesium oxychloride cement mortar. Magnesium oxychloride cement, also known as Sorel cement, is a promising alternative to conventional cement due to its rapid setting and high early strength development. However, its low tensile and flexural strengths limit its widespread application. In this research, stone crushed powder was introduced into the cement mortar to enhance its mechanical properties. The molar ratio of magnesium oxide (MgO) to magnesium chloride (MgCl2) was varied to assess its impact on the compressive strength of the mortar. A series of mortar mixtures were prepared by replacing a certain percentage of sand with stone crushed powder, while adjusting the MgO:MgCl2 molar ratio within a defined range. The compressive strength of each mortar sample was tested at different curing times. Preliminary results indicate that the molar ratio variation significantly affects the compressive strength of the stone-incorporated magnesium oxychloride cement mortar. Optimal molar ratios were observed to enhance the strength performance of the mortar, with higher ratios demonstrating improved compressive strength. Additionally, the inclusion of stone crushed powder positively influenced the overall mechanical properties of the cement mortar.
