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