Cement hydration is a complex chemical reaction that transforms inert cement powder into a durable solid read more material. When cement comes into contact with water, it initiates a series of processes involving the various constituents present in the cement clinker. This intricate interplay leads to the formation of crystals, which bind together to create a strong and cohesive mass.
The hydration sequence can be classified into several stages, each characterized by distinct chemical events. Initially, water molecules react with the cement particles, releasing heat and forming a paste-like state. As hydration progresses, solid phases begin to form, compacting the mixture.
The rate of hydration is influenced by various factors, including water content, temperature, cement type, and the presence of admixtures. Understanding the science behind cement hydration is crucial for optimizing concrete properties and ensuring its long-term strength.
