Abstract: Concrete is a widely used construction material. Cement in concrete during manufacture emits more amount of CO2 into atmosphere. Hence in order to reduce the consumption of cement industrial by products can be utilized in concrete. Bagasse ash is an ash generated from co-generation plant in a sugar industry. Disposal of Bagasse ash concrete creates many problems so it can be partially replaced for cement. Also, it possess pozzolanic properties. Structures constructed in seismic zone need special attention. Utilization of fibre in concrete improve the ductility of concrete. Attempt has been made to study the mechanical properties of concrete using hybrid fibres and Bagasse ash. Both Natural Fibre (sisal) and artificial Fibre (Polypropylene) are combined and utilized in concrete along with Bagasse ash. M20 mix design were carried out. Proportion of Bagasse ash (10%) and Polypropylene fibre (0.5%) are Kept constant and sisal fibre is varied in different proportion (0%, 0.1%, 0.2%, 0.3%) respectively. Mechanical properties such as Compressive strength, split tensile Strength and Flexural Strength are Studied. 10% Bagasse ash, 0.5% polypropylene fibre and 0.2 % Sisal fibre is found to be optimum.

Keywords: Bagasse Ash, Polypropylene Fibre, Sisal Fibre, Fibre Reinforced Concrete.
