2020-5-27Portland cement is made from clay and limestone. Once the cement has been mixed with water, a reaction commences. The chemical reactions are complex but the hydration reaction of cement with water produces insoluble silicate compounds and calcium hydroxide Scheme 1.1 and 1.2. Carbonation starts simultaneously with hydration Scheme 1.3.
