ABSTRACT
Reinforced concrete buildings are the preferred choice of water constructions such as harbour, dock, offshore construction, and other seawater structures that cannot be separated from the influence of adhesive environments. Adhesive environment can lead to expansion and corrosion. Furthermore, crystallisation of salt content in reinforced concrete pores can even lead to a decrease in reinforced concrete strength. This study aims to determine the effect of seawater content on the physical properties of concrete. The study was carried out on cylindrical test specimens with 150 mm and 300 mm diameter in wet and dry conditions immersed in seawater from the Indian Ocean (Trisik Beach, Indonesia). The specimens were tested after 28 days and 90 days. The comparator used a freshwater-immersed concrete cylinders test object. The results showed that after 28 days, the concrete strength of concrete immersed in seawater increased, but after 90 days, the strength decreased. Wet conditions on concrete will reduce the strength of concrete.
