GLASS FIBRE REINFORCED CONCRETE AND ITS PROPERTIES

Many RC constructions start to deteriorate with time and exposure to various hostile conditions. In nearly all cases, the emergence of small fissures and cracks is attributed as the cause of this early degeneration.Beginning with the casting of the structure, cracks begin to form early. Upon loading, these little cracks spread out more, which causes the structure to develop large openings. Many studies are being conducted to try and stop the spread of the early microcracks and stop the degeneration of the structure. This report’s primary goal is to To research how adding glass fibres to the mix can prevent crack progression. Research on how adding fibre to concrete improves its durability. By loading the concrete blocks to 60% of their compressive strength in order to permit the opening of surface fissures and cracks (which may be formed due to dead weight itself), an attempt is made to replicate the site conditions. The concrete blocks are then tested for alternate drying-wetting cycles. A comparison between plain cement concrete and glass fiber-reinforced concrete (GFRC) is done. Both materials are of the same grade. The improvement brought about by the additional fibres is noted as the comparative findings are plotted.
