Experimental Investigation on Steel and Polypropylene Fiber Concrete
This project presents the Result of an Experimental Investigation on the mechanical behavior of a concrete with steel and polypropylene fibers. The steel fiber of 0.7% 0.8% 0.9% and Polypropylene fiber of 0.1% 0.175% 0.25% were added together to form hybrid fiber concrete. Mechanical properties such as Compressive strength, Tensile strength and Flexural strength. The purpose of combining the fiber is to improve the multiple properties of concrete mixture. The addition of fiber to concrete is helpful to improve the fracture properties of concrete. The hybrid fiber are comprehensively being used to Rigid pavement, Airfield pavements, Flexible pavements, Earthquake Resistant and Explosive Resistant structures, mine and tunnel lining, Brick deck overlays, Hydraulic structures, RockSlope stabilization etc. The standard cube test specimen of size 15x15x15cm, cylinder test specimen of size 15x30cm were casted, cured and tested for 7,14,28 days as per Indian standard guideline using M30 grade concrete.
