Clinker replacement

This article gives a short overview of clinker substitution in cement. This includes sections about the feasibility of the technology and operational necessities, the status of the technology and its future market potential, how the technology could contribute to socio-economic development and environmental problems, the contribution of the technology to economic development, climatic effects, and financial requirements and costs. The market statuses of Clean Development Mechanism projects are also included.

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.

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.
