The use of concrete is truly large and day by day the cost of the conventional material cost is also rising. So, it is beneficial to use the optional materials for making the concrete. The project focuses on coarse aggregate in concrete. In this project work, the study has been done on the replacement of coarse aggregate with demolished brick aggregate known as jhama brick. The optional source is jhama brick as a coarse aggregate. Jhama brick produced due to over burning. The brick has irregular shape and it is also used as coarse aggregate in some places where the stone aggregate is not effortlessly available or if available its cost is high. These rejected bricks can also be an implicit source of coarse aggregate. It’s partly or completely a replacement of the conventional material. We replaced the coarse aggregate in ratios of 15%, 25% and 35% in M25 grade of concrete. A complete thirty-eight numbers of concrete samples are cast with and while not crushed jhama bricks. Tests are conducted on fresh and hardened cement concrete, for example, compressive strength test, split tensile tests and flexural test at 7 days and 28 days of curing period. The 25% replacement of jhama brick is considered as the best because of strength and economy, hence we use it in enough loaded structures the result shows that the aggregate that concrete derived from jhama brick aggregate attained lower strength than the regular concrete.
