Abstract : Self-Consolidating Concrete is a type of concrete which has the potential to flow in to the form work uniformly, with no vibration, without segregation and bleeding, and provide a good environment without the use of vibration. Self consolidating concrete (SCC) is commonly used in construction now a days. Tensile strength and durability of the SCC can be improved by reinforcing it with fibers. Flow determining part of the SCC is its mortar phase. In this work the mortar part of the SCC is used for analyzing its flow and strength properties. The fibers used in this work are coir and nylon. 1 cm and 2 cm coir fibers and I cm nylon fibers were used at a percentage of 0.125%, 0.250%, 0.300% of solid weight. Fresh state properties of the mix were measured by doing flow table test. Hardened state qualities of the mix were analyzed by performing compressive strength test. From the test result it is inferred that there is increase in the compressive strength with fiber addition. Decrease in workability is observed with fiber percentage and length of the fiber for coir fiber mortar. But there is enhancement in the workability is observed with nylon fiber. Enhancement in the compressive strength is observed with nylon fiber than coir fiber.
