Análise do impacto da incorporação de finos de resíduos de construção e demolição na performance física e mecânica de argamassas: um levantamento bibliográfico

Abstract

Since civil construction is one of the activities that most impact the environment, both in the consumption of non-renewable materials and in the generation of waste, this course conclusion work aims to carry out a literature review analyzing the effect of the partial replacement of cement by cement fines. construction and demolition waste (CDW). In the studies, the replacement content, the type of RCD, the tests carried out and the results obtained were observed. For this review, articles, monographs, dissertations and theses were searched in the Periódico CAPES, SciELO and Google Scholar databases. The search period was from 2018 to 2023. Eight relevant studies on the topic were selected. A general reduction in compressive strength was observed, however, the flexural tensile strength improved up to 15% of replacement, except for 20%. Changes in capillary absorption and void ratio were statistically insignificant.
