Effect of Size of Aggregate on the Compressive Strength of Pervious Concrete

Abstract

Now a day, due to rapid urbanization, natural resources are consumed on large amount. So to protect the natural resources various measures are being investigated by engineers. However, due to increased awareness of the need for conservation of non-renewable mineral resources, increased consideration is being given to the use of pervious concrete in most countries. No fines concrete is considered as one of the alternative to the traditional concrete. Pervious concrete would be a natural choice for use in structural applications in this age of green building. It consumes fewer raw materials than normal concrete. And hence it is required to study the behavior of no fines concrete. In this paper an attempt has been made to investigate the strength of pervious concrete by conducting various laboratory tests on the pervious concrete made, using different sizes of aggregates and different voids ratio. It is concluded that gradation of aggregate has remarkable effect on the compressive strength of pervious concrete.
