What are the advantages of blended cement over ordinary OPC cement?

Blended cement offers several advantages over ordinary Portland cement (OPC). These include:

• Reduced carbon emissions:Blended cement has a lower carbon footprint compared to OPC. By incorporating supplementary cementitious materials like fly ash, slag, or limestone, the clinker content in blended cement is reduced. Clinker production is energy-intensive and emits a significant amount of carbon dioxide.
• Improved durability:Blended cement often exhibits enhanced durability properties compared to OPC. The addition of supplementary cementitious materials can enhance the resistance of concrete to chemical attacks, sulphate attacks, and chloride penetration, resulting in longer service life for structures.
• Reduced heat of hydration:Blended cement typically exhibits lower heat of hydration compared to OPC. This is beneficial in large scale concrete applications where excessive heat generation can lead to thermal cracking.
• Enhanced workability and pumpability: Blended cement can improve the workability and pumpability of concrete. The addition of supplementary cementitious materials enhances the cohesiveness and lubricity of the concrete mix, making it easier to handle, place, and finish.
• Increased strength:Blended cement displays increased strength in long term due to the pozzolanic properties and denser particle packing which help in the construction of strong and durable structures.

Overall blended cement offers environmental benefits, improved durability, better workability, and the utilization of industrial by-products, making it a favourable choice over ordinary OPC cement for sustainable construction practices.
