LONG TERM CHARACTERIZATION OF FIBRE REINFORCED CONCRETE

ABSTRACT The present paper outlines the investigation conducts on the use of glass fibres with structural concrete. Plain concrete has very low tensile strength, limited ductility and low resistance to cracking.Internal micro cracks are innately present in concrete. Fibres when added in different proportions in the concrete improve the strain properties as well as crack resistance, ductility, as flexure strength and toughness properties. In recent times, glass fibres have also become available, which are free from corrosion problem associated with steel fibres which provide us with added advantages. GFRC is a combination of cement, glass fibres, and polymers. Alkali resistance glass fibre, having an some aspect ratio was employed in percentages, varying by percentage by weight in concrete and the properties of this FRC (fibre reinforced concrete) like compressive strength, tensile strength are studied.
