The presented research focuses on the experimental investigation to calculate the suitability of using recycled brick ballast obtained as demolition debris to serve as partial substitute to coarse aggregates for concrete of different grades like M10, M15, M20, M25 and by varying the product mix in different replacement proportions as 0%, 25%, 50%, 75% and 100% by weight. The proposed methodology is based on a series of tests carried out, focusing mainly on the workability and characteristic strength analysis of concrete with graded brick ballast and comparing them with the conventional cement concrete. The experimental work included several types of concrete made keeping the water-cement ratio as 0.45 and with target slump value 70-100 mm. The influence of replacing different percentages of coarse aggregates to produce different concrete grades was closely observed. The conclusion drawn from the test results conforms, the possibility to use brick ballast in concrete for M25 grade with 25% by weight of the coarse aggregate as optimum value.
