摘要

Pervious concrete is also called as porous concrete or permeable concrete. It is a special type of concrete which will allow water from precipitation and other types of sources to pass through it directly which reduces runoff from a site and allowing groundwater recharge. It is made of using large aggregates with little no fine aggregates. It consists of cement, coarse aggregate and water with little fine aggregates .The strength of pervious concrete is more important as permeability characteristics, its strength is very less when compared with normal concrete. Studies indicate that pervious concrete low compressive strength capacity than conventional concrete and will only support light traffic loadings. The important features of pervious concrete are its strength and properties, like density, permeability and porosity. Alarming declination in groundwater level is one of the major challenges in the country and even globally also. The groundwater levels in the nearby controlled wells show a decreasing trend alarmingly. The only source of improving groundwater level is by ground water recharge, at present most of the runoff is being let out and at last it joins the sea, if we could conserve this runoff and facilitate it to recharge the groundwater then some solace can be achieved and the groundwater level can be improved. The pervious concrete is a concrete which is having porosity more than 30% generally which will facilitate water to infiltrate. So to increase its structural properties without any effect on hydrological properties fibres are added to the design mix which will increase the strength of pervious concrete. So coconut fibre which is natural resource and economical in costwise is used in the project to give best results. Coconut fibre is available in large quantity at the test site, which makes it as a quite viable as a reinforcement material in pervious concrete. This study aimed at analyzing the variation in the strength of pervious concrete reinforced with coconut fibre at varying fibre contents and to compare it with that of conventional pervious concrete. The various strength aspects analyzed are the compressive and flexural strength of the pervious concrete reinforced with coconut fibre at varying percentages (0.25%, 1% and 2% by the weight of cement) of fibre.
