Abstract: concrete is the major product used in the construction industry. Concrete has to constantly face challenges of aggressive environment either from within or from external sources during its service life. Hence, durability of concrete with respect to exterior aggressions is one of the current priorities in civil engineering. As it has indirect effect on economy, serviceability and maintenance. Damage to concrete structures in continuous contact with saline environment is of utmost importance in all other types of damages. Upon exposure to saline water, Clions penetrate into the structures and subsequently lead to corrosion of reinforcement. The penetrated chloride also reacts with components of cement and leads to a rehydration of residual cement. Some smart materials i.e. admixtures like silica fume, fly ash, metakaolin, rice husk etc. are also being used within the concrete to increase its durability and strength. It is necessary to identify the penetration and reaction of chloride ions with these Pozzolanic materials which may alter the physical Properties of concrete either in fresh or in hardened state of concrete. In present research work, the effect of chloride ions on fresh and hardened properties of concrete is studied.
