“BISMILLAHIR RAHMANIR RAHIM” Comparative Study On Flexural Strength Of Normal Concrete Slab And Steel Wire Mesh Concrete Slab

Abstract

In this study, experimental investigations were performed on Normal Concrete and Steel wire mesh concrete to evaluate performance characteristics such as flexural Strength and load capacity. The flexural strength of concrete is one measure of the strength of unreinforced concrete. It refers to the ability of the concrete beam or slab that is being tested to resist bending. Concrete is the most widely used construction material in the modern construction practice. Due to its relatively low tensile resistance, concrete tends to experience tensile failure and cracking under external loads. To enhance the tensile performance and ductility of concrete material, possible solution including steel wire mesh reinforcement are investigated in the present study. Normal Concrete and steel wire meshes were mixing ratio 1: 1.5: 3in the concrete mixer. In this study slab specimen size was 24”x18”x5”. Experiments have been conducted using 3 slabs for normal concrete slabs and 3 slabs for Steel wire mesh concrete slabs and were tested for 7 days, 14 days and 28 days. Ordinary Portland cement (OPC) was used in our study. Results found from our test results indicate that the flexural strength of the normal concrete slab and steel wire mesh concrete slab increases with the increase of different days. Static material tests including uniaxial compression and flexural bending tests showed that the steel wire mesh addition yielded better strength. The advantages and disadvantages of using different reinforcing materials are discussed. From the results, the advantages of replacing steel wire mesh were demonstrated. In this study, in our test we found the flexural strength of steel wire mesh concrete slab to be higher than that of normal concrete slab. So we can say that steel wire mash concrete slab is better to use than normal concrete slab as per
