Abstract

This experimental study is exposing the relationship between permeability and compression strength of AR Glass fiber-reinforced concrete. In addition, it inspects the influence of AR Glass fiber reinforcement on concrete permeability. The AR Glass fibers decrease permeability of specimens with increased volume of fibres. Here an attempt is made to study the permeability of super plasticised concrete with different types of fibres. The fibres are added at the percentages varying from 0.2% to 1.0% by weight of cement at intervals of 0.20%. To maintain a good workability, superplasticiser is added at the dosages of 0.8% by weight of cement. The dosage is arrived considering the workability and strength on simultaneous reduction of cement and water content ranging from 5% to 20% of the reference concrete. The experiment was conducted in a six cell permeability cell at the pressure of 10 kg/cm2 for 100 hours. Water permeability test is conducted as per IS: 3085-1987 and it is found that on addition of fibres, the co-efficient of permeability of concrete is reduced considerably.
