Methodologies to Produce Pervious Concrete Partially Using Recycled Materials as Aggregates: A Literature Review. TecnoL. [online]. 2022, vol.25, n.53, e300.  Epub 13-Ago-2022.

The objective of this literature review was to compile and discuss the scientific literature on methodologies used to produce and manufacture pervious concrete, an innovative design alternative in pavements. In pervious concrete, coarse aggregates are partially replaced with recycled aggregates; for instance, rubber latex at 5 % and 8 % by weight of cement, fly ash between 0 % and 70 % by volume of cement, and carbon fiber at 0.27 % and 0.4 % by weight of coarse aggregate. For this literature review, we selected the most relevant publications from 2015 to 2021 indexed in the Scopus, Scielo, ScienceDirect, and Latindex databases using keywords such as “residual materials”, “coefficient of permeability”, “pervious concrete”, “degree of porosity”, and “laboratory tests for pervious concrete”. The results show that the compressive strength of this material varies between 0.5 MPa and 97.3 MPa; its tensile strength, between 1.6 MPa and 5.29 MPa; and its permeability, between 4.63 mm/s and 10.2 mm/s. The desirable percentage of fly ash to optimize pervious concrete is up to 20 %; higher values negatively affect its mechanical properties. In conclusion, pervious concrete presents parameters within the ranges established by regulations: compressive strength, 17.5 MPa; tensile strength, 2.6 MPa; and permeability, 6.1 mm/s. Therefore, it has significant value because it contributes to microstructural level enhancement and greater durability, which makes it an advantageous and useful product in modern times.
