Carbon sequestration in cementitious composites using biochar and fly ash – Effect on mechanical and durability properties

A possible reduction in high CO2 emission associated with cement production can be achieved by sequestering CO2 as carbonate mineral in hydrated cement matrix. This study aims to investigate application of biochar and its combination with fly ash to improve CO2 uptake and carbonate mineralization in cement mortar. Effect of fly ash and biochar, from waste peanut shell, on carbonate mineralization, strength, permeability and shrinkage of mortar...
