Özet

For structures in a marine environment, only sulfate resisting cement is recommended in many specifications in Turkey. However, the performance of this cement against chloride effect is not taken into account. One of the effective ways of minimizing the chloride permeability is to use mineral admixtures in concrete. The main objective of this study was to obtain more information on the effects of mineral admixtures on the rapid chloride permeability of mortars. Two types of cement, a blended cement and a sulfate resisting cement, were used to prepare the mortar mixtures in which the cements were partially replaced by the locally available ground granulated blast furnace slag, fly ash and a natural pozzolan. Mixtures were prepared at two different water/binder ratios. Rapid chloride ion permeability test according to ASTM C1202 was carried out on the mortars. Compressive and flexural strength and capillary water absorption of the specimens were also obtained. The test results confirm that, sulfate resisting cements have low resistance against chloride penetration and the use of pozzolanic materials is a more effective method for increasing the resistance.
