A detailed investigation on concrete specimens (100 mm diameter and 200 mm height) made with different chemical admixtures was carried out after 10 years of tidal exposure. Chemical admixtures include an air-entraining admixture (AEA) (vinsol), a water-reducing admixture (WRA) (lingosulfonate group), various high-range water-reducing and air-entraining admixtures (HRWRAEAs) (naphthalene, melamine, polycarboxyl, and amino-sulfonate group), and a drying shrinkage-reducing admixture (glycol ether plus amino alcohol derivatives). The specimens were tested for compressive strength, Young's modulus of elasticity, carbonation depths, chloride ingress, pore size distribution, electrochemical and physical evaluation of a steel bar's corrosion in concrete, examination,of steel-concrete interfaces, and mineralogy of the mortar portions of concrete. The naphthalene group of chemical admixture shows the best performance against strength development and chloride ingress prevention in concrete. Contrarily, the polycarboxyl group shows the least performance. The special method of casting concrete causes the formation of a good steel-concrete interface that prevents the initiation of corrosion 'even for a chloride concentration of more than 2% of cement mass.
