What are the four basic chemical compounds that make up portland cement, and what effect do they have no portland cement concrete?

Basic chemical compounds of Portland cement:

• Four basic chemical compounds present in the Portland cement are
• Tricalcium Silicate
•  Dicalcium Silicate
•  Tricalcium Aluminate
• Tetra calcium Aluminoferrite

Effects of chemical components:

Tricalcium Silicate (C₃S): This compound is responsible for the initial set and the early strength of the cement. Higher percentage of C₃S have higher early strength of the cement.

Dicalcium Silicate (C₂S): This compound will hydrates and hardens very slowly. It is also helps to increase the strength of the structure.

Tricalcium Aluminate (C₃A): This compound is helpful for the hydration and hardening of the strength. It will hydrates large amount of cement helps for early strength. To stop the hydration of C₃A, add a small amount of gypsum. It is added to prevent the quick setting of the cement immediately when water is added.

Tetra calcium Aluminoferrite (C₄AF): This compound will give only little strength. The color of the Portland cement affects due to the presence of C₄AF.
