Evaluation of Mechanical characteristics and Structural Behavior of Basalt Fiber Reinforced Concrete

Abstract

Worldwide, a great deal of research is currently being conducted concerning the use of fiber Reinforced
Concrete. Laminates and Sheets in the strengthening and repairing of reinforced concrete members. There have also
been several advances made in the development of fiber reinforced concrete to control cracking and crack
propagation in plain concrete, and to increase the overall ductility of the material. However, there are now many types
of fibers with different materials and geometric properties, but the exact fracture behaviour of fiber reinforced
concrete materials is not clearly understood. Majorly, Synthetic fiber has played a dominant role for a long time in a
variety of applications for their high specific strength and modulus. In this project the overall aim is to utilize and
evaluate the performance of natural based Basalt fiber in the concrete which it has as an properties which it is similar
to synthetic fibers.The optimum percentage of Basalt fiber in concrete was found with respect to cube compressive
strength, split tensile strength and flexural strength at the age of 28 days. The specimen was casted for different
percentages such as 0.05%, 0.10%, 0.15%, 0.20%, 0.25%, 0.30%, 0.35%, 0.40%, 0.45% and 0.50% by the volume of
concrete. By keeping the optimum level of dosage of fiber the structural behaviour of reinforced concrete column was
evaluated.
