Abstract:
Incorporating biochar, as a material with a high amount of sequestered CO2, in cementitious mixtures could be a promising approach to address the global concern of reducing the carbon footprint of concrete structures. This presentation will evaluate the application of biochar as LWA with internal curing capabilities in cement-based mixtures. This assessment will be done in terms of how compressive strength, autogenous shrinkage, and internal relative humidity (IRH) are affected in the presence of two types of biochar from different manufacturers. The above-mentioned effects will be studied at 2 different particle size distributions for both types of biochar to see how a better advantage of using biochar as LWA in concrete could be taken while reducing concrete's carbon footprint.
