Abstract
In this research used iron filling as partial replacement fine aggregate at percent 5,10, and 15% by weight of fine aggregate and maintaining the ratio of water to cement at 40% and study observe that produces concrete with high compressive strength, tensile and flexural strength at replacement percent I10% and production of concrete with a lower coefficient of thermal expansion with continued replacement and thus obtaining the maximum distance between expansion joints at the rate of addition of I15%.
