Added different percentages of iron slag ,which can be considered solid waste plants as well as iron and bauxite clays to Iraq Portland cement to improve its properties. 3- 15 wt % of slag added to the cement and 2-10 wt % of bauxite added to the slag accumulating .
The obtained results showed that ,the compressive and impact strength after 28 days from the date of preparation of samples has increased with the increase in the percentages of slag content until (9%) , and then decrease their by increasing Slag contents while in case , slag and bauxite were used to gother , we noted that , the
compressive and impact strength were decreased by increasing slag and bauxite percentages .
