Abstract

The use of concrete construction has recently grown very rapidly because concrete has beneficial properties such as high compressive strength and easy implementation to form according to construction requirements. Concrete is much influenced by the constituent materials (cement, aggregate, and water), and the added material. Besides, it is especially also influenced by environmental conditions. Concrete also has weaknesses like low flexural strength, so that the construction is easyly cracking if it gets a stretch. This study aims to determine the effect of exposure to seawater on the compressive strength and flexural strength of concrete with added material, caustic soda (NaOH) in the composition of 0%, 1%, 1.5% and 2.5% for plain water and sea water environments. Concrete quality plan fc '30 Mpa for compressive strength and concrete quality plan flexural strength fs 4.1 Mpa. To know the characteristics of concrete by comparing the two results test of the compressive strength and the flexural strength of concrete in plain water and sea water. Soaking was done at 7 days, 14 days, 28 days, and 90 days. The highest compressive strength occurs in plain water immersion at the age of 28 days with a composition of caustic soda of 0% (31.02 Mpa), and the highest flexural strength of concrete occurs at 90 days of immersion in plain water with a composition of 0% caustic soda (4.78 Mpa). From the research results, it can be concluded that the use of caustic soda in seawater does not show an increase in compressive strength or flexural strength.
