This new cementing blend uses natural pozzolan sourced from the Kingdom of Saudi Arabia to create concrete with a lower environmental impact.
*Abstract
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. Its use of pozzolan and limestone may also result in a more economical concrete than traditional OPC. The product can be used as a sustainable concrete in the construction of green buildings, civil infrastructure, and other concrete products.
