Use of Agricultural by-Products as Alternative Supplementary Cementitious Materials in Concrete

The cement industry emits approximately 814-935 kg of carbon dioxide. Using supplementary cementitious materials (SCMs) to substitute part of the cement content in concrete is considered an effective method to reduce the carbon footprint of concrete and improve its fresh and hardened properties. To respond to the relative scarcity of traditional SCMs or their localization (whose transport causes environmental and economic problems), locally available agricultural residues of rapeseed (canola) and sunflower will be developed and assessed to be utilized as alternative sources of SCMs. The partner organization will explore the potential for these novel ashes from silicon-rich residues as alternative sources of SCMs for new construction and rehabilitation of concrete bridges and pavements, and hence re-evaluation of its current specifications on supplementary cementitious materials.
