“…as expansive agents in mass construction) (Gao et al, 2008;Mo et al, 2014) since their hydration rate is lower than those of reactive MgO or Portland cement (PC). Alternatively, the use of reactive MgO in cement-based formulations does not create any potential late expansion problems due to its similar hydration rate to PC (Dung and Unluer, 2017a;Dung and Unluer, 2017b).…”

“…The durability behaviour of cementitious materials with MgO, studied by different researchers, is summarized in Table 4 . In general, the incorporation of MgO leads to lower water absorption [ 45 , 47 , 52 ], higher carbonation [ 41 , 48 ], higher chloride ion migration coefficient [ 41 ], higher initial expansion [ 37 , 39 , 42 , 43 , 46 , 47 , 57 , 58 ], and lower shrinkage [ 42 , 43 , 53 ].…”

“…The researchers defined 1% of MgO as an optimal amount to obtain maximum improvements of the mechanical strength and water absorption of mortars. Dung and Unluer [ 51 , 52 ] also studied the water absorption of concrete mixes produced with MgO and found a decrement when compared to that of conventional mixes.…”
