GLASS FIBER REINFORCED CONCRETE [GFRC]

The present day world is witnessing the construction of very challenging and difficult civil engineering structures. Quite often concrete being the most important and widely used material is called upon to possess very high strength and sufficient workability properties. Efforts are being made in the field of concrete technology to develop such concretes with special characteristics. In the view of the global sustainable developments it is imperative that fibres like glass carbon polypropylene and aramid fibres provide improvements in tensile strength fatigue characteristics durability shrinkage characteristics impact cavitations erosion resistance and serviceability of concrete. Fibres impart energy absorption toughness and impact resistance properties to fibre reinforced concrete material and these characteristics in turn improve the fracture and fatigue properties of fibre reinforced concrete research in glass fibre reinforced concrete resulted in the development of an alkali resistance fibres high dispersion that improved long term durability.
