India: The Global Cement & Concrete Association (GCCA) India has released a report entitled ‘Blended Cement – Green, Durable & Sustainable’ to promote the advantages of different types of blended cement over Ordinary Portland Cement (OPC). The report was released by Anil Agrawal, Additional Secretary Department for Promotion of Industry, and Internal Trade (DPIIT), Ministry of Commerce & Industry at an online event hosted by the Indian branch of the Global Cement & Concrete Association (GCCA).

“Blended Cement is the top priority and will play a key role in decarbonising the infrastructure segment. I am happy to see that the global cement and concrete industry has taken the lead, and they have come up with a roadmap. Now the Indian cement sector is developing an India specific detailed roadmap for the cement and concrete industry to achieve the net-zero CO₂ concrete by 2050 in a time-bound manner,” said Agrawal.

The report is a collation of the information about blended cement and its advantages. It highlights the performance improvement possible through this replacement, making blended cement an attractive means to achieve sustainable infrastructure development. It also showcases the benefits of different blended types of cement over OPC based on hydration, microstructure and permeability, rheology and workability, strength development, shrinkage (chemical, autogenous, and drying) and cracks, leaching, alkali-aggregate reactivity, sulphate attack, reinforcement corrosion, long-term durability of construction and usage in preparation of high strength concrete.
