Experimental Investigation on Concrete using Carbon Fibers and Partial Replacement of Cement with Metakaolin

Abstract

Major construction activities performed using concrete which is good in compression. The major draw backs of concrete are brittleness and crack formation which decreases the durability and strength. This paper reviews the some of the research published on different uses of adding carbon fibers and partial replacement of cement with metakaolin to the concrete. In this experimental investigation the  focus on adding carbon fibers and replacing metakaolin with appropriate proportions on M30 grade i.e., different percentages (0.40, 0.80, 1.00, 1.20, and 1.60%) of carbon fiber reinforcement by the volume of concrete. Percentage of metakaolin as partial replacement with cement (5, 10, 15, 20 and 25%) to determine the properties of fresh and hardened concrete. The destructive methods of testing conducted on compressive and split tensile strength test. The specimens also tested and evaluated the strength by performing non-destructive tests such as ultrasonic pulse velocity and rebound hammer test.
