Abstracts: Technology in Concrete has been developing in many ways to enhance the quality and properties of concrete. One of the most important technological advances in improving the quality of concrete is by the usage of admixtures. Admixture is a substance which is added during or before mixing the concrete, typically to improve its properties. Our study is conducted to evaluate the possibility of incorporating some industrial waste material, which are abundantly available in our country, as an admixture for concrete mix design and fly ash bricks. The workability and compressive strength of the concrete and water absorption and compressive strength containing industrial waste material, are evaluated, as per the standard norms, in the course of this study. The same criteria are also measured for PCC and Fly Ash Bricks, these values are compared. Slump test has been done to determine the change in workability of the fresh concrete mix with waste material as compared to that of fresh PCC. Similarly, water absorption of fly ash bricks with waste material as compared to that of Fly Ash Bricks. Compressive strength test has been done on each sample of concrete and brick with the Compression Testing Machine (CTM) to determine the compressive strength of each specimen. The values thus obtained, of different parameters, as mentioned above, are crucial in determining the viability of replacing the comparatively costlier admixtures by easily available cheaper industrial waste.
