Mineral admixtures are being used today almost in all concretes partially, to improve workability, engineering properties and also to enhance durability of the concrete. These are industries by-products. This paper discusses, blast furnace slag (BFS) was used to study durability properties; namely, initial water absorption, final water absorption and acid attack. To examine the above mentioned properties, M30 concrete was chosen. The BFS content was varied from 0% to 30% by volume of cement with an interval of 10%. In acid attack, specimens were cured in H2SO4 solution about 3% concentration, the corresponding weight losses (%) were evaluated for curing periods of 7, 14 and 28 days. The durability properties of the BFS-modified concrete have been improved when BFS content increased up to 20% advantageously. Weight loss was also decreased.
