Department of civil engineering 2 Abstract Pervious concrete is a special type of concrete, which consists of cement, coarse aggregates, water and if required, admixtures and other cementitious materials. As there are no fine aggregates used in the concrete matrix, the void content is more which allows the water to flow through its body. So the pervious concrete is also called as Permeable concrete and Porous concrete. The concrete paste then coats the aggregates and allows water to pass through the concrete slab, pervious concrete is traditionally used in parking areas, areas with light traffic, residential streets, pedestrian walkways and green houses. It is an important application for sustainable construction and is of many low impact development techniques used by builders to protect the water quality. Pervious concrete has been increasingly used to several sustainability-relative benefits offered by this material.
- 3. Department of civil engineering 3 Introduction • Pervious concrete has been in use for more than 50 years, especially in the United States and Japan. It contains a high amount of pores, with cement paste evenly distributed throughout its structure. • The porosity of pervious concrete ranges between 11% and 35% which gives it permeability, good drainage properties, and high noise absorption characteristics; however, the high porosity also reduces the concrete’s strength.
- 4. Department of civil engineering 4 Background study • Porous Concrete (PC) pavements have been gaining a lot of attention in recent years, especially in urban areas because they are capable of mitigating the water and air environmental impacts caused by conventional roads. • To this end, the investigations undertaken during the last decade (2009–2018) in this topic were, analyzing and predicting their future potential developments. 171 publications in the topic were found in Scopus database. • where mechanical and hydraulic capacity are the two main properties studied in PC pavements, with 36% and 41%, respectively. In addition, a predicted growth for 2019–2030 of 2.51% (4.29 PC publications per year) is expected.
