The use of biochar in construction materials emerges as a potential solution to improve mechanical and physical properties, in addition to contributing to environmental sustainability. This work reviews the applications of biochar in cementitious materials, such as mortar and concrete, including its use as a substitute for aggregates and cement, as well as filler and additive, through N publications indexed between 2020 and 2025. Therefore, it is noted that biochar improves compressive strength, reduces autogenous shrinkage, and increases the durability of cementitious composites. Additionally, the potential of biochar in sensor materials is explored, due to its electrical conductivity, reinforcing its technological versatility. Based on the bibliographic analysis, the technical and environmental feasibility of using biochar in construction is highlighted, aligning with the principles of the circular economy and the reduction of greenhouse gas emissions. This overview seeks to encourage new studies and practical applications.
