This paper describes the use of an accelerated test method for durability of mortars using various cements exposed under the combined wetting and drying cycle conditions to seawater, simulating the concrete structures in marine environment. The mortar specimens were prepared using 12 types of cement and various water-cement ratios. The specimens were dried at 30, 60 and 80°C for 6 hours and subjected to wetting at 30°C in substitute seawater with salt concentrations of 0, 3.27 and 6.54 percent. Damage to the specimens exposed to such conditions is classed according to the following three types : scaling, cracking and sound due to attack by seawater and thermal shock.
