COSTA, Marcus Luiz Alves dos Santos et al. Analysis of concrete characteristics with the replacement of natural fine aggregate by industrial solid waste. Rev. ALCONPAT [online]. 2022, vol.12, n.3, pp.328-346.  Epub Apr 08, 2024. ISSN 2007-6835.  https://doi.org/10.21041/ra.v12i3.573.

The objective of this study comprises the use of industrial solid waste in terms of improving the mechanical properties of cement composites. Therefore, the incorporation of granitic “crushed” powder and marble powder in the manufacture of cement-based composites was evaluated, partially replacing the natural fine aggregate at levels of 50% and 100%. For that, tests were carried out to characterize the aggregates, in addition to the evaluation of the axial compressive strength of the specimens. The results showed that the mixtures containing 50% of recycled aggregate give the material a compressive strength of 29.09 MPa, that is, 4% higher when compared to the reference mixtures, making the results satisfactory, demonstrating the viability of recycled aggregates on concrete pieces.
