Concrete setting is the chemical process by which cement paste reacts with water to transform a plastic concrete mix into a solid, load-bearing material. The setting is driven by hydration reactions that progressively bind cement grains into a cohesive matrix.
During hydration, calcium silicate hydrates and calcium hydroxide form, releasing heat. The early stage allows placement
Two standard milestones are the initial set and the final set. Initial set marks the loss of
Curing, the maintenance of adequate moisture and temperature after setting, continues hydration and minimizes shrinkage and
Common factors affecting setting include water content, aggregate characteristics, and the use of accelerators, retarders, or
