Abstract: Random dispersion of short discrete fibres in concrete resulted in fibre reinforced concrete (FRC) and this has been proven to be an effective method of improving strength and durability properties of control mix. Drying shrinkage is observed in concrete as it gets hardened and this shrinkage results in cracking. Cracks will act as a gateway to deleterious substances and cause failure of the reinforced cement concrete (RCC) structures, if proper care is not taken in minimizing the drying shrinkage of the concrete. Metallic and synthetic fibres have been found to be effective in minimizing the drying shrinkage of concrete. However, synthetic fibres are derived from hydrocarbons and they cause greenhouse effect. Hence, a natural fibre is considered in this study. An experimental investigation was carried out to evaluate and compare the effect of steel, polypropylene (PP) and sisal fibres on M30 grade concrete. Polypropylene FRC outperformed as compared to steel and sisal FRC in reducing the drying shrinkage.
