Sustainable resources management and development have been at the forefront of important issue concerning the construction industry for the past several years. Specifically, the use of sustainable building materials and reuse waste materials is gaining importance and becoming common place 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 material 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, CSAT and UPV 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%, 10%, 20%, 30%, 40% and 50%. 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 addition of low Percentage of bricks kiln dust. The results show that the optimum replacement of recycled bricks kiln dust with fine aggregates was 30%. Up to 30% replacement, it is possible to gain the same strength as conventional concrete
