Explained
Here are some differences between OPC and PPC cement:
Composition: OPC is made from limestone, clay, and other materials. PPC contains OPC and pozzolanic materials, such as fly ash, volcanic ash, or calcined clay.
Setting time: OPC typically sets faster than PPC.
Strength: OPC gains high strength during the initial casting stage, while PPC is relatively weaker. However, PPC's long-term strength is greater than OPC's.
Heat of hydration: PPC generates less heat during the curing process than OPC. This makes PPC advantageous for large concrete structures where controlling temperature rise is important.
Durability: PPC is more durable due to less water permeability.
Environmental considerations: PPC is environmentally friendly because it uses recycled waste products in its production.
Uses: OPC is used for projects that require quick setting, such as the construction of buildings and bridges. PPC is used for building standalone houses, schools, and residential building slabs. It's also suited for construction in areas that regularly contact soil or water containing sulfates. PPC is also ideal for mass concrete works like dams, retaining walls, and large foundations.
