Usefulness of concrete is known to every body, as it has very vast scope in the modem society. We use concrete starting from the foundations to dome of high rise buildings, from drains to canals and aqueducts, from drain covers to big-big bridges joining main lands with islands, from canal linings to harbour structures and other huge water front structures. However, when ever a structure, be small or large, is erected it takes time. Most of the prominent structures are erected in stages. There are always joints between the two consecutive stages. These joints are bound to have some effect on the strength of the structure depending on the time gap between two stages, preparation of joints, inclination of joints, roughness of joints, and so on. This fact should be given proper attention and systematic investigation should be carried out. Keeping in view, the proposed basic research program has been planned. It is proposed to study the effects of joints on the strength of concrete in the following manner:
i) To study effect of joints on the strength of concrete.
ii) To study the affect of inclination of construction joints on the strength of concrete.
The compressive cube test is conducted to get the value of compressive strength of concrete cubes with joints and without joints. A comparison of both is made and conclusion is reported
