A Study on Mechanical Properties of Fly Ash Based Concrete with the Addition of Glass Fibre

The present day world is going through the construction of very innovative and unsymmetrical   engineering structures. Glass fibre is a material consisting of numerous extremely fine fibers of glass. Quite often, concrete possess very high flexural and shear strength properties.  Researchers all over the world are attempting to develop high performance concretes by using various fibres and other admixtures in concrete up to certain proportions with low water-cement ratio. Glass-fibre reinforced concrete (GRC) is a material made of a cementitious matrix composed of cement, sand, water and superplasticizers, in which short length glass fibres are dispersed. It has been widely used in the construction industry till now for non-structural elements, like thin slab panels, piping and roof tiles ..etc. GRC offers many advantages, such as being lightweight, fire resistance, good appearance and strength. To increase the applications of Glass Fibre Reinforced High-Performance-Concrete (GFRHPC) in India, greater understanding of GFRHPC produced with locally available materials and indigenously produced mineral admixtures is essential. The present study includes testing of concrete cubes with different glass fibre proportions for its strength corresspondingly at 28 days.
