This concrete is used in the construction of permeable sidewalk, parking lot and roadway in order to reduce storm water runoff and increase the efficiency under raining condition. In addition, pervious concrete can be used as materials for water purifying, acoustic and thermal insulation, and artificial fishing reef. Pervious concrete is, therefore, classified as an environmentally friendly concrete. For Thailand, however, there is still limited amount of research, body of knowledge and utilization of pervious concrete. This article aims to provide knowledge of basic properties of pervious concrete from past researches and other informations. The history, mix design and proportioning, utiliza- tion and testing of various properties of pervious concrete are included. Keywords: pervious concrete, voids, aggregate, cement paste
