The Potentialities of Glass Fibre Reinforced Concrete for Structural Uses.(Dept.C)

Abstract
The behaviour of steel reinforced concrete beams having glass fibre layers as additional reinforcement at different heights of the beam tension side was investigated. Deflections, longitudinal strains, initial cracking loads as well as cracking pattern and ultimate failure loads for each beam are presented and discussed. Steel reinforced concrete beams without glass fibres were also cast and tested for comparison. Preliminary tests were carried out on plain concrete beams reinforced with glass fibre layers. The contribution of glass fibre reinforcement lies mainly in increasing the beam flexural rigidity and hence less deformations and higher initial cracking loads and ultimate strength.
