Concrete Properties Enhancement with use of Carbon Fibers
Abstract
Concrete standard grade of concrete with high strength with mechanical properties like flexural strength as well as split is a requirement / need for today’s fastest construction work. To improve the mechanical properties there is need for adding fibers in concrete. Distinct fibers available in worldwide out of which carbon fibers had showed very effective solution for enhancing high strength mechanical properties of concrete. In this paper we have designed M35 grade of concrete with addition of 0%, 0.75%, 0.915%, 1.08% and 1.245% of carbon fiber. We have casted 45 No. of Cubes, 15 Nos. of Cylinder and 15 Nos. of Beams overall we have casted total 75 Nos. of specimens. The testing was done on concrete for fresh and hardened properties of concrete i.e. workability, Compressive strength for 3 days, 7 days and 28 days, Split tensile for 28 days. It was observe that the concrete having 0.915% of carbon fiber shows the economical mix with higher mechanical properties.
Keywords: Carbon fiber, concrete, flexural strength, mechanical properties, beams.
