Mock-up pragmatic study on the impact performance of self-compacting concrete incorporating sea sand.

ABSTRACT: Self-Compacting Concrete (SCC) allows for the use of non-desalted sea sand as a fine aggregate, but the durability of triple mix SCC with partial sea sand replacement remains unclear. To optimize binder and fine aggregate replacements, tests for consistency, setting times, soundness, compressive strength, and Ultrasonic Pulse Velocity were performed. Six SCC variations, incorporating 30 % Class F Fly Ash (FA), 5 % Ground Granulated Blast Furnace Slag (GGBS), and various fine aggregate combinations, were evaluated for their fresh, mechanical, microstructural, and durability properties. Results demonstrated that SCC with 50 % sea sand and 50 % manufactured sand achieved superior 90 th day compressive strength. This improvement was attributed to accelerated cement setting and enhanced FA reac
