Sustainable resources management and development have been at the forefront of an important issue concerning the construction industry for the past several years. Specifically, the use of sustainable building materials and reuse of waste materials is gaining importance and becoming commonplace in many areas. As one of the most commonly used construction materials in the world, concrete composed of natural aggregate, natural sand, cement, and water, out of these raw materials for concrete, cement can be manufactured in industries but natural aggregates are non renewable resources and depleting at an alarming rate, results in scarcity of good quality natural occurring aggregates (coarse and finer one). In the present study the hardened properties like compressive strength, split tensile strength, and also durability properties like ISAT, test were carried out on Brick kiln dust concrete. The percentage of bricks kiln dust that partially and fully replaced by fine aggregates by weights were 0%, 20%, 40%, 60%, 80% and 100%. Experiments were conducted for both Ordinary Concrete and bricks kiln dust Concrete with different percentages of BKD. It is observed from the experimental results and its analysis, that the compressive strength of concrete, splitting tensile strength of concrete increases with the addition of low Percentage of bricks kiln dust. The results show that the optimum replacement of recycled bricks kiln dust with fine aggregates was 20%. Up to 20% replacement, it is possible to gain the same strength as conventional concrete. Beyond 20% replacement the strength results following a decreasing trend.
