Resumo
The production of concrete in dosing plants is growing and, with this, there is also an increase of inherent residues of the production process. The objective of this paper is to verify the panorama of the research related to residual sludge of concrete with emphasis on its recycling in masonry units. In order to do so, the systemic mapping was performed with the purpose of finding main publications and studies referring to the desired slope, through the CAPES Periodic database, and the searches belong to two main topics: the use of residues in concrete masonry and studies related to concrete sludge waste. In general, it can be observed that there is a great variety of residues applied in masonry, being the most studied the use of fly ash and construction and demolition residues. On the other hand, there are still few studies that use residual sludge in concrete products, mainly for the production of masonry. In this context, it is understood that there is no consensus regarding the best use of concrete sludge waste, emphasizing the need for research to corroborate or contradict the results obtained. Finally, this work points to a residue that has not yet been studied, but with possible applications in new research. Its characteristics such as the presence of SiO2 and CaO indicate a potential for use as a binder, which can lead to a reduction in the consumption of cement.
