UltraTech Cement Head Research and Development Interview Questions, Process, and Tips

Flyash can improve the strength and durability of bricks by reducing water absorption and increasing resistance to chemical attacks.

• Flyash is a byproduct of coal combustion and contains silica, alumina, and iron oxide which can react with lime in bricks to form calcium silicate hydrate, enhancing strength.

• Incorporating flyash in brick production can reduce the amount of clay needed, making the bricks more sustainable a...read more

It depends on the specific requirements and goals of the project.

• PSC (Portland Slag Cement) is known for its higher long-term strength and durability compared to PPC (Portland Pozzolana Cement).

• PPC is more environmentally friendly as it uses fly ash as a raw material, reducing carbon emissions.

• PSC is typically more expensive than PPC due to its superior quality and performance.

• The choice between PSC and PPC should be b...read more

PPC offers higher quality and durability compared to OPC.

• PPC has lower porosity and higher resistance to chemical attacks compared to OPC.

• PPC produces less heat during hydration, reducing the risk of thermal cracking.

• PPC has better long-term strength and durability due to its pozzolanic properties.

• PPC is more environmentally friendly as it reduces carbon dioxide emissions compared to OPC.
