INVESTIGATING THE IMPACT OF SEAWATER CURING ON THE COMPRESSIVE STRENGTH OF CONCRETE

Abstract

Concrete is a widely used building material due to its many advantages over other construction materials. However, the quality of the concrete is greatly affected by the treatment given during its manufacture. Treatment is crucial for obtaining high compressive strength, water-tightness, and resistance to wear and dimensional stability. When concrete is used in coastal areas, it often comes in contact with seawater, which contains compounds that can reduce its durability. This study aims to determine the impact of seawater curing on the quality of concrete by comparing it with fresh water curing. The study was conducted with a planned concrete quality of K250 at 28 days, with 20 samples for each treatment. The data was analyzed using the provisions of SNI 03-1974-1990. The results showed that the use of seawater for curing reduced the compressive strength of concrete compared to fresh water curing. The study highlights the importance of water quality in concrete treatment and its impact on the durability and strength of concrete structures.
