Abstract: (19 Views)
With the ongoing industrial development and the expansion of reinforced concrete structures—predominantly concentrated in coastal regions—the need for designing and evaluating self-compacting concrete (SCC) has grown substantially. This study focuses on the incorporation of polycarboxylate-based superplasticizers, silica fume, and calcium carbonate powder in SCC mix designs, particularly for concrete exposed to or cured in seawater environments. The findings indicate that the high chloride content in seawater accelerates the hydration process, shortens setting time, and enhances early-age compressive strength. Moreover, laboratory results demonstrate that polycarboxylate superplasticizers effectively mitigate the adverse effects of chlorides. SCC specimens cured in seawater exhibited relatively higher compressive strength compared to those cured in potable water.
