USE OF AGRICULTURAL RESIDUES BASED BIOCHAR AS SELFCURING AND CARBON SEQUESTERING ADMIXTURE IN CEMENTITIOUS COMPOSITES: A REVIEWSOURAV GHOSAL, P.K. PANI, R.R. PATTANAIK3 AND M.K. GHOSALAbstract This article focusses on the possible applications of biochar in the concrete mixture from strength, durability, sustainable cementitious material, waste disposal and carbon sequestration points of view. The yield of the biochar has been reviewed only from the agricultural residues which are plentifully available and are mostly unutilized in agricultural based countries causing severe environmental problems. The findings of the studies undertaken by the various researchers reveal that there is a potential of improving strength, durability, enhancing internal curing activity, reduced permeability, decreased autogenous shrinkage etc. in concrete and sequestering carbon in civil infrastructures, if biochar is used as admixture in cementitiousmaterials. Based on the studies, it is inferred that the biochar would be the future potential cementitious material in construction industry to solve many problems related to self-curing activity, high performance concrete, environment and waste management. |
