WebCalcination conditions controlled the performance of recycled samples, which were fully decomposed at 700 °C. Recycled samples demonstrated 15–20% lower strengths than original samples, attributed to changes in MgO reactivity, aggregate properties and interaction between aggregates-cement paste. WebNov 27, 2024 · In this study, reactive MgO (in powdered form), as a filler and as a percentage of cement, was added to rock flour mortar. Also, hydration mechanism was used for curing the samples. Then effects of it on mortar rheology were investigated.
