Experimental Study on Interface Behaviour of Masonry Structures

Masonry structures are durable in nature and are resistant to variations in climatic conditions. In Civil Engineering Projects, nowadays the usage of different types of structural blocks (Clay bricks, fly ash bricks and solid blocks) are increasing. Masonry structures accommodate minor earth disturbances and normally will not lead to failure in differential settlement of foundations. This thesis work is an experimental study of Compressive strength, Modulus of elasticity and Poisson's ratio for different mix proportions. Tests were conducted for mix proportions 1:4, 1:5 and 1:6 for masonry prisms. The type of bond used for the experiment is English bond. Dimensions of masonry prisms were 230mmx230mmx 300mm. The specimens prepared were tested on 7th and 28th day of curing. Specimens of 3 each in all mix ratios were tested which made a total of 63 prisms. The results were verified using the model created in ANSYS. The experimental results were compared and plotted which proved that the prism with fly ash brick masonry achieved maximum young's modulus and Poisson's ratio.
