STUDY OF AXIAL STRENGTH OF FRP- CONCRETE ELEMENT OF DIFFERENT CROSS-SECTIONAL ASPECT RATIO

civil engineering

Strength of concrete is a prime property which represents structure’s ability. To improve concrets strength and cracking resistance there are many ways but use of fiber is one which got popularity in industry. The fibres are used in concrete to control crack. So here in this project our aim is to perform axial strength tests on fiber reinforced concrete element for different aspect ratio. In the present work we fabricated, tested and compare distinct fiber reinforced polymer composite concrete element of different aspect ratios. The properties of these FRP concrete elements are compared with plain concrete elements having different aspect ratio. The fibres used are hooked end steel fiber. The grade of concrete is M25. In this experiment three aspect ratios-1.3, 1.6 and 1.9 are selected and percentage of steel in each case is 1.5% by weight of cement. Compressive strength test and Split tensile strength test were conducted on several cylinders to measure the effect of steel fibres on strength of concrete. For each aspect ratio of element three cylinders were tested for compressive and tensile strength test at curing period of 7 days and 28 days respectively. This will be beneficial to society where innovative structural designs are to be implemented by use of concrete
