Abstract
Concrete is a weak building material in tension. Inherently, micro cracks will be present in concrete. The formation of micro cracks is normally due to shrinkage of concrete. Fibers when introduced act as bridge towards crack propagation and increase the energy absorption capacity of the concrete. Moreover, concrete suffers from low tensile strength, limited ductility and little resistance to cracking. In order to improve these properties, an attempt has been made to study the effect of addition of polypropylene and glass fibers in ordinary Portland cement concrete partially replacing cement with flyash. In the investigation, it is mainly focused on the effect of mechanical properties on M 60 grade of concrete by providing hybrid fibers with different dosage levels by volume of concrete.
