Experimental Evaluation of Sodium Silicate-Based Nanosilica against Chloride Effects in Offshore Concrete

摘要: This study investigates the effect of a new pore filling material, named sodium silicate-based nanosilica (SS), on resisting diffusion chloride ions. The proposed SS is chosen, mainly due to its smaller particle size, compared conventional ethyl nanosilica. Each chemically treated have negative (−) charge surface. Four types mixes with different amounts partial replacement fly ash and slag are prepared. Effect water binder ratios (0.35, 0.40, 0.45) also examined. Test results showed that inclusion was significantly beneficial for protecting concrete from attack. At given strength, in up three times more effective than control without SS. It believed these excellent attributed small size chemical surface treatment In this study, experiments compressive hydration heat, accelerated neutralization, sulfate erosion tests were conducted find general fundamental properties durability concrete.
