The term 'curing' in masonry specifically refers to the process of maintaining moisture in concrete to ensure it reaches its desired strength. Concrete requires a certain level of moisture during its initial setting period to facilitate the hydration of cement particles. Proper moisture retention is crucial as it allows the concrete to cure properly, leading to maximized strength and durability.

When the concrete dries out too fast, it can lead to incomplete hydration, resulting in weaker concrete that may crack or fail under stress. Therefore, techniques such as misting the surface, using wet burlap, or applying curing compounds are employed to keep the concrete sufficiently moist during the curing phase.

The other options do not accurately capture the essence of curing in masonry. While drying out mortar or removing excess mortar are aspects of the masonry work, they do not relate to the process of curing, which is fundamentally focused on the hydration state of concrete. Similarly, adding water to wet bricks is not relevant to the curing of concrete, as it pertains more to brick preparation rather than the curing process itself.
