Abstract: A Chloride ion is a key factor affecting durability of concrete structures. In order to investigate chloride migration in behavior of mortar cubes, mesoscopic heterogeneity of mortar should be considered. This investigation presents comparison of cement mortar cube with and without using of Hydrochloric acid (HCL) and Sodium Chloride (NaCl). For this purpose, standard cement mortar specimens 70.6 mm x 70.6 mm x 70.6 mm were prepared and tested to find the compressive strength and volume change. The prepared specimens were allowed for 28 days curing and tested by Non-Steady State Chloride Migration setup (NSSCM) at different voltages of 25V, 30V, 35V, 40V. The volume change at these voltages is 4.05%, 6.43%, 3.25%, 7.99% and change in the compressive strength is 64%, 60%, 48%, 56% respectively.
