Biochar helps lime-based building materials capture more carbon while gaining strength

Natural hydraulic lime has been used for centuries in masonry and restoration because it is compatible with traditional building materials and can absorb carbon dioxide as it hardens. Now, researchers have found that adding a small amount of finely ground biochar could strengthen this lime-based material while helping it capture more CO2.
