Abstract: Due to rapid urbanization and development of smart cities, paved areas have been increased rapidly. Un-paved pervious areas are converting into impervious paved areas, which affects on many environmental factors, such as ground water table, average atmospheric temperature and green house effect, which are major current issues for environmentalists. Pervious concrete is one of the solutions to defeat this problem and research has been done by many researchers all over the world on the effective utilization of pervious concrete, especially in pavement sector. Due to complex behavior of pervious concrete, it is difficult to maintain proper balance between strength and permeability. In this paper property of hardened concrete with various percentage of fine aggregate has been determined experimentally in addition to various tests have been conducted to observe important properties, like compressive strength, density and permeability. Influence of fine aggregate on these properties is presented in this paper. As there is no approved standard method to determine permeability of pervious concrete, falling head permeability test method has been used by preparing own apparatus. Optimum strength and permeability results have been obtained on percentage of fine aggregate less than 15 percent.
