EFFECT OF CHOPPED GLASS FIBER ON STRENGTH AND DURABILITY OF CONCRETE

Construction industry is fronting a very thought-provoking and renowned structures. Architectures provoke their work from artistic point, whereas we civil Engineers provoke our work from strength and durability point. In order to maintain the aesthetic view of a structure without affecting its strength and durability many exertions have been made in the field of concrete technology. In the outlook of achieving suitable sustainability, it is authoritative that fibers like steel, glass, hemp provide enhancement in the strength of the concrete. Among the research, glass fiber spectacles good fracture, toughness and energy absorption property. Such glass fiber shows higher resistance to alkali action and corrosion, which improves the durability of a concrete. In this study to improve the workability of concrete polycarboxylate ether was used as super plasticizer. Here we present the overview on strength and durability improvement of concrete on addition of 0.25%, 0.5%, 0.75% and 1% of chopped glass fibers in concrete. Various strength tests like compressive strength test, Split tensile strength test and flexural strength test and durability tests like acid attack and fire resistant test were performed. In addition to the above tests, a study on role of polycarboxylate ether on the improvement of workability of concrete was presented.
