ASSESSING THE INFLUENCE OF SALT WATER ON CONCRETE INCORPORATING BIDA NATURAL STONES AS COARSE AGGREGATE .
Abstract:
This study investigates the use of salt water in concrete mixing and curing, alongside traditional water-only methods, with Bida natural stones as coarse aggregates. Concrete, a composite material comprising cement, fine and coarse aggregates, and water, undergoes a chemical reaction between cement and water to form a solid mass with significant compressive strength but limited tensile resistance. The research involved casting and curing 144 cubes for 7, 14, 21, and 28 days, utilizing a mix ratio of 1:2:4 and a water-to-cement ratio (w/c) of 0.5. The physical and mechanical properties of the aggregates were determined, and the compressive strength of the hardened concrete was assessed at various curing periods. The resulting concrete exhibited a slump range of 0 to 135 mm, compressive strength ranging from 8.94 N/mm² to 27.11 N/mm², and density ranging from 1757.04 kg/m³ to 2198.52 kg/m³. The study concludes that salt water can be embraced rather than feared for concrete casting and curing, particularly in coastal environments, when applying a mix ratio of 1:1.5:3 for grade M20.
