Question-1: What is the chemistry of cement?#N#Answer: When all of the constituents of Cement are mixed and burnt together with each other, it leads to the formation of some complex chemical compounds which are not formed simultaneously and are called bogues compounds, like Tricalcium aluminate, Tetra calcium alminofer rate, tricalcium silicate, and Dicalcium silicate.
What happens when cement is mixed with water?
When Cement is mixed with water and aggregates, it undergoes an exothermic reaction called hydration. The chemical substance in Cement reacts with water to form hydrates products, also known as hydration products.
Why is alumina used in cement?
Alumina is used for imparting quick setting property to the cement. Also, it acts like flux in reducing the clinkering temperature during the preparation of cement. If alumina is present in excess, then Cement reduces its strength as well.
What is low heat cement?
Low heat Cement is a special type of Cement having low heat of hydration, and this can be achieved by increasing the proportion of dicalcium silicate and reducing the proportion of tricalcium silicate and Tricalcium aluminate. This Cement also develops a slower rate of gain of strength.
