This project is conducted to observe the potential concrete made with replacement of 10 %, 20 % and 40 % iron ore to sand. The DOE method was used in designing the concrete mix for the concrete and then modified to replace 10 %, 20 % and 40 % of the sand by iron ore. The study was conducted in laboratory to investigate the behavior of the concrete in term of mechanical strength as well as the physical properties. In terms of mechanical strength, the harden concrete was tested for its compressive, and flexural strengths. The physical properties of fresh concrete were indicated by slump test. Several concrete samples were cast and cured using normal curing and tested at 7, 14 and 28 days. The concrete density up to 2459 kg/M obtained in this study. The result indicated that compressive strength increase with the age of sample. The flexural strength and compressive strength of concrete, with iron ore decreased as a percentage increase in the replacement of iron ore. This can be concluded 40 % was not capable to be used but there may be some condition that need for this percentage. Nevertheless, the result had proven that concrete with iron ore is denser and heavy than conventional concrete. 3 was
