Bibliometric review and insights on pervious concrete as an eco-friendly material

Pervious concrete (PC) is an environmentally friendly construction material with an interconnected void structure that regulates stormwater runoff, reduces urban heat islands, and promotes groundwater recharge. This review study employs scientometric tools to examine nearly 30 years of PC research based on Scopus-indexed publications. Extensive research has been conducted on PC production methods and performance; this paper conducts a systematic review of its applications using Preferred Reporting Items for Systematic Reviews and Meta-Analyses and enhanced by VOSviewer’s bibliometric mapping of keyword clusters, international co-authorship, and citation trends. Studies show that there is a growing interest in PC research for achieving sustainable urban development. However, the review identifies a lack of emphasis on the scientific rigour of the underlying research, such as experimental methodology consistency, sample size adequacy, and statistical significance. This review study also inspects different developments in PC material configuration, mix designs, mechanical and structural characteristics, and the relationship between porosity, permeability, and load-bearing capacity. The addition of supplementary cementitious materials, like as fly ash, silica fume, and so on, increases PC performance and also helps to recycle the industrial wastes. The combination of bibliometric insights and technical evaluations can strengthen PC’s contribution to sustainable infrastructure development.
