To achieve the efficient utilization of magnesium slag, this study investigates use fly ash, and metakaolin as partial substitutes for cement in cementitious materials. The reactivity these materials is assessed based on compressive strength mortar. response surface methodology employed to explore influence material proportions performance mechanisms underlying development composite system are examined through XRD, SEM, TG-DTG, BET analyses. Additionally, effect slag drying shrinkage properties mortar studied. experimental results indicate that exhibits low cannot be used alone an active admixture. optimal proportion metakaolin, 10:10:10:70, achieving over 80% pure approximately 1.5 times containing 30% slag. Furthermore, helps mitigate volume caused by Therefore, can facilitate comprehensive construction sector, reducing its negative impact ecological environment.
