| Abstract | ||
| Steel slag which can be considered as solid waste pollutant was used in concrete mixture for road bases and surfaces, bridges, asphaltic concrete, clinker raw material and other fields, instead of cement or filling material. In this work, steel slag was used as replacement of aggregate or stone, which has the highest content in concrete mixture. Four groups of concrete mixtures with (0, 25, 50 and 60%) by wt. of steel slag from Basrah steel plant were used instead of aggregate. The first group, without slag, as a standard mixture was used to compare its properties with those of (25, 50 and 60%) by wt. steel slag. The obtained results showed that, density of concrete and compressive strength, also flexural force, after 7 days and 28 days were increased by increasing slag content, while water absorbed content was decreased by increasing slag content. Those results insure the importance of using steel slag not only in modification of concrete properties, but also to save the environment from huge quantities of slag as solid waste. | ||
