Experimental Study of Light Weight Concrete Using PP Fiber
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 2
Abstract
Concrete is acknowledged to be a relatively brittle material when subjected to normal stresses and impact loads, where tensile strength is approximately just one tenth of its compressive strength. the addition of steel reinforcement significantly increases the strength of concrete, the development of micro cracks must be controlled to produce concrete with homogenous tensile properties. The introduction of fibres is brought in as a solution to develop concrete with enhanced compressive and tensile strength, which is a new form of binder that could combine Portland cement in bonding with cement matrices. The influence of polypropylene fiber improves the performance characteristics of the lightweight cement composites. Fiber may be used in two different lengths 6mm , 12mm and 19mm and fiber proportions can be taken as 15%, 25% and 35% by cement weight in the mixture design. Hardened concrete properties can be evaluated at 7, 14 and 28-day by testing compressive strength and tensile strength with w/c ratio 0.5%. The use of fiber makes the concrete light weight and low cost material. , Fibre Reinforced Concrete have wide variety of usages in structures such as heavy-duty pavements, Airfields, industrial floor, water retaining and hydraulic structures, parking structure decks, water and waste water treatment plants, pipes, precast roof and wall panels, and the techniques of shotcrete application.
