What do we call the process of softening mortar by adding water and mixing?

The process of softening mortar by adding water and mixing is referred to as tempering. This term is used in masonry to describe the adjustment of the consistency of the mortar, making it easier to work with. When water is added to mortar, it enhances the flow and workability, allowing masons to achieve a better bond with bricks or blocks.

Tempering is especially important because it helps in ensuring that the mortar does not dry out too quickly during application, which can impact the strength and durability of the final structure. It is crucial to achieve the right balance of moisture in the mortar for optimal performance during the setting and curing process.

While other terms like diluting or hydrating may seem relevant, they do not specifically capture the notion of adjusting mortar for improved workability. Diluting often implies a thinning effect that may not be suitable for mortar, while hydrating generally refers to the process of adding water to cementitious materials to initiate the chemical reaction of hydration. Blending does refer to mixing, but it does not solely focus on the softening process associated with mortar. Therefore, tempering precisely describes the intended action of preparing mortar for masonry work.
