Comparison of Confined Burnt Clay Brick Masonry Prism and Fly-Ash Brick Masonry Prism

The paper comprises the experimental study of compressive behaviour of confined masonry prism to investigate the characteristics of confined masonry structure and comparison of the compressive strength of burnt clay brick masonry prism and fly-ash brick masonry prism. Stress- strain curve and Impact hammer test is used to determine the modulus of elasticity of masonry. Linear regression analysis is carried out to establish relation between modulus of elasticity of masonry and compression strength of masonry prism which can be used in analysis and design procedures. It is observed that confined masonry prism of lesser mortar grade has comparable strength and stiffness than unconfined masonry prism of high strength mortar grade. Data acquisition system used for impact hammer test is a sixteen channel vibration analyser that helps avoid the cumbersome destructive test of masonry prism
