In my opinion, PSC (Premium Slag Cement) fits the most. Because of the construction qualities, it is ideal for house construction. PSC is a blended cement. Slag is a product that is non-metallic and is 90% glass. With silicates of lime, these qualities make the PSC ideal to be used in mass construction.

The raw material is crushed, and then heated at temperature in excess of 1000 degree Celsius in rotating kiln to become clinker. Clinker is then mixed with gypsum and ground to a fine powder to produce final grade of cement.
