| 520 | _aThe Portland limestone cement with the Mineral Admixtures (metakaolin and silica fume) were used in this research to study their impact on the durability of concrete and the corrosion of steel in reinforcement concrete.the corrosion of reinforcement steel in concrete is the main factor which decrease the durability of concrete and therefore decrease the age of the Buildings. The research aimed to increase durability of concrete by decreasing the concrete permeability.The results showed that the samples contains (CEM II,CEM II(SF5),CEM II(SF15)and CEM II(MK5)) improved the compressive strength when compared with (CEM I), the results of the corrosion test showed that the samples contains (CEM II(SF15),CEM II(SF15 + MK5)and CEM II(MK5)) improve resistance of the Reinforced concrete against the corrosion when compared with (CEM I) and for the permeability test the samples contains ( CEM II.L,CEM II(SF15 +MK5), CEM II(SF15+MK5),CEM II(MK5) and CEM II(SF15) decrease the permeability of concrete when compared with (CEM I). It was concluded that the sample contains (CEM II (SF15)( gave the highest results in the )compressive strength test , resistance of corrosion of steel in the reinforced concrete and also reduced concrete permeability) by percentages (16%, 35% and31%) respectively when compared with the ordinary Portland cement (CEM I) | ||
