Cement hydration

Cement hydration is the chemical process that occurs when water reacts with cement particles, causing them to harden and develop strength. When mixed with water, cement forms a paste that binds together like glue, creating a solid mass over time. This process produces new compounds, primarily calcium silicate hydrate and calcium hydroxide, which give concrete its durability and strength. Hydration begins immediately after mixing and continues for days or even months, gradually transforming the mixture into a solid, durable material suitable for construction.
