Abstract: 
Cementatious materials have been used by mankind for construction from time immemorial. The every rising functional requirement of the structures and the capacity to resist aggressive elements has necessitated to develop new concrete composites materials to meet the higher performance and durability criteria. The environmental factors and pressure of utilizing waste materials from industry have also been the major factors in new developments in the field of concrete technology.
High performance concrete has been used in various structures all over the world since last two decades. The development of High Performance Concrete (HPC) has brought about the essential need for additives both chemical and mineral to improve the performance of concrete. Most of the developments across the work have been supported by continuous improvement of these admixtures.
Hence an attempt has been made in the present investigation to study the durability behavior of glass fibre-reinforced High Performance Concrete. To attain the set out objectives of the present investigation, an aggregate binder ratio of 2.0 and w/b 0.30 has been chosen and cement has been replaced partially with fly ash in four different percentages viz. 0, 10, 20 and 30% and glass fibers by with volume percentages of 0, 0.5, 1.0, & 1.5% respectively have been used. Hardened concrete is tested for permeability properties. The results are quite encouraging for use of glass fibers in producing durable High Performance Concrete. The various details of permeability tests on glass fiber reinforced high performance concrete will be presented in this paper.
