Abstract

Abstract This study evaluated the physical, hydraulic, mechanical, and thermal properties of pervious concrete (PC) incorporating Red Brick Waste (RBW) as partial cement replacement. The experimental program involved evaluating physical characteristics (density and porosity), hydraulic behavior (permeability), mechanical performance (compressive, tensile, and flexural strength), and thermal performance (solar reflectance) in relation to the variation in the content of cement replacement by RBW in pervious concrete. In addition, regression analyses were performed to evaluate the ideal percentage of RBW replacement in the pervious concrete to improve its mechanical and thermal performance for pavement applications. The experimental approach was divided into six stages: waste preparation, materials characterization, pervious concrete design and production, concrete mixture characterization, statistical analysis, and regression analysis. The ANOVA one-way confirmed that the RBW generated interference in all the evaluated properties of the pervious concrete mixtures. At a 5% replacement rate of cement by RBW in the PC mixture, porosity and permeability were lowest, and density was highest. The percentage of 5% of RBW promoted the highest compressive and flexural strengths for PC. The use of RBW contributed to increasing the solar reflectance of PC. Since all evaluated properties of the pervious concrete designed with 5% RBW met the minimum requirements of Brazilian standards for pavement applications, it was concluded that this replacement rate is ideal for the good performance of the pervious concrete dosed with this type of waste.
