Why Is Limestone Essential In Cement

Why Is Limestone Essential In Cement . 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.

Question: Why Is Limestone Used In Cement? Ceramics

The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement. As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash. What is the use of limestone in cement?
