Impact of elevated curing temperature on mechanical properties and microstructure of MgO‐based expansive additive cement mortars

MgO‐based expansive additive (MEA) is uniquely used in China to compensate for the thermal shrinkage. For mass concrete, its inner temperature can soar up to 60°C due to the accumulation of hydration heat, which will strongly impact the mechanical properties and microstructures. In this paper, the i...
