Abstract
Fibers are generally added to concrete to improve strength, durability, toughness. As fibers are a materials which is used to resist the development of tensile forces in concrete. Generally, steel, polypropylene, polyester, sisal, glass and carbon fibers are used as fibers. This paper deals with the results of mechanical properties of steel-sisal fiber reinforced concrete for various mix proportions. The specimens were casted with steel and sisal fibers in the mix proportion of 0%-40% with total volume fraction of 2%. The objective of this study to study the effect of inclusion of hybrid fibers on the compressive strength, modulus of elasticity and flexural strength. The results showed that the hybrid fiber reinforced concrete with mix proportion of 60% Steel and 40% Sisal shows consistently improved strength compared to the other mix proportions.
