Abstract:
The use of carbon- and cellulose- based waste biomass byproducts and nanomaterials presents a key technology for modifying the carbonation kinetic rates within the cementitious matrix, due to their unique CO2 uptake potential and porous/fibrillar morphology. This presentation demonstrates the development of sustainable, net-zero and negative concrete with high CO2 sequestra-tion capacity, resiliency and ductility by replacing ordinary Portland cement with biochar and waste cellulose fibers and reinforcing it with nanomaterials. This is a promising way for developing ecoefficient and highly resilient concrete, with at least 2-3x higher CO2 capture and mineralization ability and 100% increased pre-crack and post-crack tensile load bearing and strain energy absorption capacity over OPC concrete throughout the entire life cycle.
