Biochar Concrete, Cementitious Materials, Sustainability, Bibliometric AnalysisAbstract
The search for alternatives capable of reducing the environmental impact of cementitious materials has intensified the interest in biochar as a functional component in concrete and mortars. Produced through the pyrolysis of different biomasses, this carbon-rich material features high porosity, structural stability, and a chemical composition favorable to interaction with cement-based matrices. These characteristics have motivated investigations into its mechanical performance, microstructural influence, and contribution to carbon sequestration strategies. Recent studies indicate that small fractions of biochar can modify hydration processes, enhance the interfacial transition zone, and act in the refinement of the pore network, resulting in gains in strength and durability under specific conditions with defined parameters. In parallel, its incorporation offers the potential to decrease emissions associated with cement production and to add value to agricultural, forestry, and urban waste. The bibliometric analysis conducted in the Scopus database highlights the global expansion of this research field over the last decade, with emphasis on mechanical performance, sustainability, microstructure, and carbon sequestration. The gathered information allowed for an understanding of current trends, identification of limitations, and pointing out directions that can be explored for the development of more efficient composites.
