Clinker replacement

Shree Cement (SCL) is one of the leading Indian cement companies and has made a remarkable presence in national cement industry through its sustainable growth philosophies. Approach for transforming risk into opportunities has bestowed it with many low hanging fruits. SCL is having presence in the cement and power sector. It is the largest cement producer in North India and among top five cement groups in the country.

When mixed with lime, pozzolanas (pozzolanic ash) set and harden like a cement, making them an alternative to Portland cement.

Pozzolanas and lime are the basis for alternative cements used instead of ordinary Portland cement. Testing is needed to determine the quality of the pozzolanas available.

Cement is a global commodity, manufactured at thousands of plants. The industry is consolidating globally, but large international firms account for only 30% of the worldwide market. The principal and most visible market for cement is the construction industry in a multitude of applications where it is combined with water to make concrete. Most modern civil engineering projects, office buildings, apartments and domestic housing projects use concrete, often in association with steel reinforcement systems.

This new cementing blend uses natural pozzolan sourced from the Kingdom of Saudi Arabia to create concrete with a lower environmental impact. By replacing targeted percentages of ordinary Portland cement (OPC) which produces large amounts of CO2 with natural pozzolan and limestone KAUST has created a new concrete product that reduces CO2 emissions by approximately 80% over standard OPC concrete. In addition to the lower environmental impact KAUST’s cement blend exhibits excellent workability impermeability and strength.
