Abstract: From past few years, researchers are working on conventional concrete reinforcing with carbon nano fibers and nano tubes to study its electrical behaviour. Reinforcing carbon fibers in conventional concrete makes concrete self-sensing that concrete can be used for health monitoring of structures, traffic monitoring, etc. Therefore the present study is performed on mechanical and durability properties of SCC concrete reinforced with carbon fibers. SCC mix used in present study is reinforced with carbon fibers from 0.5% to 2.5% by weight of cement. Different tests, namely slump flow, V-funnel, L-box and U-box test were conducted to check the rheological properties of freshly mixed SCC. Results obtained for all the mixes were within prescribed limits by EFNARC. The durability and mechanical properties of hardened concrete were studied to check different strengths. In mechanical properties, compressive strength was observed to increase when fiber dosage was up to 1% by weight of cement and later decreases as the dosage of fibers was increased from 1.5% to 2.5% by weight of cement. Split tensile strength, flexural strength was observed to be increasing for increasing dosage of carbon fibers. The durability of concrete also increased as fiber dosage.
