chemical reactions in portland cement industry

2019 2 22   HYDRATION OF CEMENT It is the reaction s eries of chemical reactions of cement with water to form the binding material. In other words, in the presence of water, the silicates C3S and C2S and aluminates C3A and C4AF form products of hydration which in time produce a firm and hard mass the hydrated cement paste.
