Study on the Strength Behaviour and Performance Evaluation of Fiber Reinforced Concrete

Concrete is one of the most widely used construction material in today’s world. Cement being one of the essential constituents of the concrete. Glass fibre has been used over 30 years in several construction members. Plastic fiber-reinforced concrete offers significant advantages in improving crack resistance, durability, and impact resistance, making it a valuable material in construction, especially in non-structural or lightly loaded applications. This study was done to find out the strength parameters of concrete using glass fiber and plastic fiber in concrete in different grades of concrete. The use of Glass fiber as partial replacement of cement, fine & coarse aggregates gives an increment in strength at certain percentage GFC & PFC as partial replacement of coarse aggregates in concrete. In this study it is found that there is a marginal increase of strength in 7- & 28-day’s the compressive strength for 3% addition of GFRC & PFRC in concrete, initially the compressive strength start increasing but, as the increment of FRC in concrete percentage the strength gets decrease and similarly the same behaviour with flexure strength and split tensile strength also found the similar strength parameters.
