Portland cement and slag cement are both commonly used in construction, but they have distinct properties and applications. These differences can influence the choice between Portland and slag cement based on the specific requirements of a construction project.

Key Differences:
Portland Cement: Commonly used for general construction purposes, including concrete, mortar, and masonry.
Slag Cement: Used in specialized applications where enhanced durability and resistance to aggressive chemicals are required.
Portland Cement: Typically sets faster and achieves higher early strength.
Slag Cement: Often results in higher long-term strength due to the slower hydration process.
Portland Cement: Production is energy-intensive and generates significant CO₂ emissions.
Slag Cement: Generally considered more environmentally friendly.
