Recent Studies on the Properties of Pervious Concrete; A Sustainable Solution for Pavements and Water Treatment

Pervious concrete a sustainable solution with limited fines or no fines and interconnected voids, has many environmental benefits, such as reducing the stormwater run-off, improving the groundwater table, reducing water pollution, and mitigating urban heat island. Many research works have been done in Pervious Concrete (PC) by varying different parameters such as, types of aggregate, aggregate gradation, water-to-cement (w/c) ratio, cement-to-aggregate ratio, geopolymer binder, ultra-high strength Matrix and compaction techniques. All these parameters have direct influences on the strength, porosity, permeability, hydraulic efficiency and durability characteristics of PC. The main aim of this paper is to review the recent work carried out in pervious concrete under six different categories (i) Effect of binders, coarse aggregate, admixtures and fibers used in PC (ii) Mechanical and durability properties (iii) pore structure characteristics (iv) Study on Clogging Effect (v) Role of PC in the water purification process and (vi) Numerical model in PC.
