An Experimental Study on Pervious Concrete in Strength and Permeability by Using RHA, SCBA, Nylon and Polypropylene Fiber

Description

There is lot of research work is going in the field of pervious concrete. The compressive strength of pervious concrete isless when compared to the conventional concrete due to its porosity and voids. Hence, the usage of pervious concrete is limited even though it has lot of advantages. If the compressive strength of pervious concrete is increase, then it can be used for morenumber of applications RHA, SCBA and nylon fiber and pervious concrete with RHA, SCBA and polypropylene fiber. For now, the usage of pervious concrete is mostly limited to light traffic roads only. If the properties are improved, then it can also be used for medium and heavy traffic rigid pavements also. Along with that, the pervious concrete eliminates surface runoff of  storm water, facilitates the ground water recharge and makes the effective usage of available land. This project was to improve the compressive strength characteristics of pervious concrete. But it can be noted that with increase in compressive strength the void ratio decreases. Hence, the improvement of strength should not affect the porosity property because  it is the propertywhich serves its purpose. In this investigation work the compressive strength of pervious concrete is increase by a maximum % age of RHA, SCBA and nylon fibre and pervious concrete with RHA, SCBA and polypropylene fibre. Were added to standard pervious concrete. When we used the 6 % RHA and 6 % SCBA with nylon fibre and polypropylene fibre in pervious concrete in various proportion of 0.1%, 0.15%, 0.2%, 0.25% and 0.3% of the weight of concrete, the result obtained by the compressive strength of nylon fibre with 6 % RHA and 6 % SCBA and polypropylene fibre 6 % RHA and 6 % SCBA is up-to 0.2 % of used result get increased.Comparative research in nylon fibre with 6 % RHA and 6 % SCBA and polypropylene fibre with 6

% RHA and 6 % SCBA used in pervious concrete, the result of polypropylene fibre with 6 % RHA and 6 % SCBA is more.
