Effect of high temperature on coconut fiber Reinforced concrete

Abstract

The fiber acquired from the dry external covering of the coconut fiber named as “coir” has the best sturdiness among all naturally available fibers. These coir strands tend to be utilized as a support in minimal expense substantial designs especially in seismic tremor districts due to their property of durability and toughness. The present study is a laboratory investigation on determining the robustness of Coconut Fiber Reinforced Concrete (CFRC) and its behavior under high temperatures. Adopting the mix design of M20, various specimens were prepared by inclusion of coconut fibers and cured. Set of cube and cylindrical specimens were subjected to temperature 200⁰C separately and compared with control specimens to determine variation in strength. A study comparing the strength aspects of CFRC, and conventional concrete subjected to normal room and high temperatures at various ages of concrete is made.
