Brief content	The use of biochar was in the last decade limited to agricultural applications as a soil amendment and carbon sequestration method. However, the use of biochar in building materials, especially in concrete, could also significantly reduce carbon footprint by replacing different dosages of cement and natural aggregates, as the cement industry representing one of the largest sources of anthropogenic carbon dioxide (CO2) emissions. The capability of biochar CO2 capture from the air in building materials and adding CO2 saturated biochar to building materials directly lead to carbon footprint reduction. The addition of biochar impacted on mechanical, physical, and chemical properties of cementitious composites and improved durability of these composites, where the dosage of biochar played an important factor that improved the durability of cementitious composites.
