Abstract
Ordinary cement concrete possesses a very low tensile strength, limited ductility and little ductility to cracking leading to brittle failure of concrete. Modification in traditional cement concrete has become mandatory to meet the functional and durability requirements of structures. Many attempts are being made to improve the mechanical properties, durability and serviceability of the structure by adding different types of fibres in specific percentage to concrete. In this work, the effect of steel fibres on the strength properties of concrete of M40 grade have been studied by varying the percentage of fibres in concrete and it is found that optimum dosage of steel fibre is around 1.5%.
