Addition of biochar in concrete for improved carbon sequestration
With the increasing rate of modernization, the carbon dioxide emission from cement production is bound to increase and so as the built-up areas. There is a potential of sequestering carbon in the civil structures. Biochar, a by-product of pyrolysis of biomass can be utilized in the concrete as an addition and/or replacement to cement. The objective of this thesis was to investigate the carbon sequestration potential of biochar amended concrete; as well as to measure the compressive strength of biochar concrete. Prepared biochar concretes were cured in water for 28 days and tested for study. The carbon dioxide concentration data was collected using the data logger. The data were displayed and assessed with the help of data logging software – Tiny Tag explorer. As the percentage of biochar increases the amount of carbon dioxide adsorbed is also observed to increase. Additionally, it is also important to assess the influence of biochar in compressive strength of concrete. High amount of biochar addition resulted a decrease in strength of a concrete. However, the results indicated clearly that biochar amended concrete can be an effective alternative to capture carbon and reduce the carbon footprint of a cement industry.
