In everyday life the need for clean water is increasing but the potential sources of clean water are getting smaller, so it is necessary to think about alternative uses of clean water in concrete construction. In this regard, research was carried out using seawater as a mixture and as a curing agent. Concrete has the disadvantage of not being able to withstand tensile forces so that in its development it is given reinforcing steel with the aim of being able to withstand tensile forces. This study aims to analyze the effect of marine materials on the mechanical properties of concrete and formulate a model of the relationship between the mechanical properties of concrete (compressive strength and split tensile strength) using sea water and sea sand. This research is experimental in the laboratory. The level of reinforcement used is 0.0% by weight of cement. Compressive strength, split tensile strength and flexural strength tests were carried out to evaluate the mechanical behavior of the concrete being made. The results showed that the mechanical properties of SCC concrete (compressive strength, split tensile strength and flexural strength) made from marine materials (seawater and sea sand) increased with increasing levels of reinforcement used. The relationship curve between split tensile strength and compressive strength tends to form an exponential power function equation. With the regression equation, for all use of reinforcement materials can be written TSCC – 0% SB = 0.0911 (fc)1.0074
