TestHub · Accepted Answer

In curing cement plaster, water is sprinkled to facilitate the hydration of cement. This process forms calcium silicate hydrate (CSH) gel, which consists of interlocked needle-like crystals. These crystals provide the strength and hardness to the plaster. Without sufficient water, hydration is incomplete, leading to weaker, less durable plaster.

The chemical reactions involved are complex, but a simplified representation of cement hydration is:

$C e m e n t + H_{2} O \to CS H g e l + C a (O H)_{2}$

The CSH gel is the primary strength-giving component.
