Abstract
Scientific articles related to the incorporation of residues in civil construction materials are growing worldwide, although their practical application is still incipient. In this scenario, this paper produced an occurrence map of the most studied residues in Brazil when incorporated in cement-based composites. Initially, the most relevant residues were identified through a bibliometric analysis on the Scopus database, using the software VOSviewer. This analysis included scientific papers from Brazilian institutions published from 2001 to 2022 regarding the development of cement-based composites using residues, wastes, or tailings. Subsequently, to map the occurrence of these materials in each Brazilian state, we used public and private data on the country’s industrial production and waste disposal. From 1272 articles analyzed, we identified 49 residues with at least 2 citations. Among the most cited residues in Brazilian publications are construction and demolition waste, rice husk, glass waste, sugarcane bagasse, and tire rubber residue. The authors noticed the heterogeneity of the occurrence of the residues across the large Brazilian territory and found gaps on research trends involving them. These and other observations facilitate the decision-making process regarding logistics and investments related to the reuse and recycling of these materials.
