Basic knowledge of cement a), Chemical composition of cement and hydration of clinker compounds Of the above figures, Alite has the most first hydrate reaction, therefore Alite contributes considerably to short term strength and the hydrate reaction completely finishes for a few months. While the hydrate reaction speed of belite is lower. As the result, the development of the short term strength is low, but it effects the long term strength. Alite reaction with water is the most activity, and interstitial material is also high reaction with water.(see figure 1).
