What are the 4 most common types of chemical admixture added to the concrete?
- Air-Entraining Admixture.
- Accelerating Admixture.
- Water Reducing Admixture.

What are the properties of admixture?
Improves properties of fresh concrete such as workability, cohesion and reduces segregation and bleeding. Improves properties of hardened concrete – For every 1% of air there is a 4% loss in strength which is minimized by the reduction in water content.

Which chemical is used in cement?
Portland cement is made up of four main compounds: tricalcium silicate (3CaO · SiO2), dicalcium silicate (2CaO · SiO2), tricalcium aluminate (3CaO · Al2O3), and a tetra-calcium aluminoferrite (4CaO · Al2O3Fe2O3).
