N2 - The performance of pervious concrete (PC) depends significantly on the constituent materials used in its production. Cement is the main ingredient of PC that serves as a binder and significantly affects PCs short- and long-term performance. However, its use in PC is not environment-friendly, owing to the emission of greenhouse gases in its manufacture. Meanwhile, economic growth has led to the production of massive amounts of industrial by-products and wastes. Recent research has aimed to tackle both problems with a single sustainable solution, i.e., beneficially recycling these wastes as a sustainable replacement to cement rather than wastefully disposing of them in landfills. Also, their use as supplementary cementitious materials (SCMs) could enhance the economic viability of PC production as its overall cost decreases. As such, the utilization of SCMs in PC while examining their impact on performance has received considerable attention in recent years. This study aims to quantitatively investigate the effect of replacing cement with various SCMs on PC's short- and long-term performance through a detailed meta-analysis. Compressive strength, permeability, and abrasion resistance characterized the mechanical, hydraulic, and durability performance. Data were obtained from research conducted over the last few years (2013-2021). For mixes made with a single SCM, it was observed that the mechanical and durability performance decreased compared to those of the cement-based counterparts while the hydraulic properties increased. Yet, all values exceeded the minimum requirements for using such PC in pavement applications. On the other hand, mixes made with two SCMs noted an increase in mechanical, hydraulic, and durability characteristics. Based on the conducted meta-analysis, it was concluded that a sustainable pervious concrete could be produced with partial replacement of cement by SCMs with limited impact on performance.
