When mixed with water Portland cement undergoes the following changes: 1. The tricalcium silicate, 3CaO.SiO2, loses a molecule of lime, which at the same time hydrates; the remainder of the compound unites with the added water to form an amorphous, indefinite, hydrated silicate of calcium which slowly loses more calcium hydrate by hydrolysis.
