Study of permeable concrete for paving: an analysis of compressive strength

Abstract

The study of permeable concrete for pavements has emerged as a sustainable solution in the face of disorderly urbanization in Brazil, seeking to mitigate flooding events. The article, based on a bibliographic review of scientific articles from the last 20 years, uses sources such as Google Scholar, SciELO and the Catalog of Theses and Dissertations, covering languages such as English, Portuguese and Spanish. In addition to exploring the global context and presenting various applications of permeable concrete, the work also addresses its advantages, such as low cost and sustainability, as well as disadvantages, notably low resistance. Details on resistance, application standards, history and properties such as porosity and the curing process are thoroughly discussed. It also emphasizes the importance of permeable concrete in reducing urban flooding, highlighting its viability due to its affordable production cost and high porosity. A review of case studies, highlighting the results of different permeable concrete mixes, contributes to understanding the complexity of its behavior, especially in relation to compressive strength. The article outlines crucial aspects, including coating typology, infiltration systems and general design requirements for this type of concrete. The coefficient of permeability is presented as a vital parameter, with detailed test methods for various coatings. The research emphasizes the need for prior evaluation of the permeability coefficient in the laboratory, underlining its importance in the effectiveness of permeable sidewalk. In short, the work provides a comprehensive guide for future research and practical applications of permeable concrete in paving, highlighting its potential as an environmentally responsible solution in urban contexts.
