Abstract
The large places covered with impermeable surfaces such as concrete and bitumen impart major impact on ground water table. In many developed nations, the utilization of pervious concrete for the development of vehicle parks and carports, is becoming popular. Moreover, pervious concrete has an important application for the sustainable construction. It is one of the many low impact development techniques and it has several environmental benefits as it allows surface runoff to infiltrate into the ground to replenish ground water. With the aim of development of material specification for pervious concrete, it is necessary to conduct tests to evaluate its performance of this new type of high-performance concrete.The pervious concrete is produced by using conventional cementitious materials, aggregates, and water. Laboratory tests were conducted for testing the performance of pervious concrete such as permeability tests, split tensile strength, density and compressive strength. The pervious concrete highly depends on its water permeability factor. In India, the rainfall intensity is less at some region and the evaporation losses are more. Therefore, the result of this investigational study provides a useful information about pervious concrete and its application as permeable pavement. Adding fibres into concrete mix enhances the properties of concrete. Short fibres manufactured from steel, glass and synthetic materials are used to enhance the cracking resistance of concrete. This is known as Fibre Reinforced Concrete Naturally happening vegetable fibres, including sisal and jute, are also used. Recron-3s fibre is a polypropylene fibre used in enhancing the tensile strength of concrete. Combination of polypropylene fibre and pervious concrete is a unique concept that has been used in this project. Mix concrete aggregate and concrete with variation in the Recron-3s fibre content. After investigation for varying percentage content of the fibres in the pervious concrete, with the increase in the fibre content, increase in the split tensile strength & compressive strength and decrease in its permeability have been observed.
