The effect of sodium hydroxide solution concentration on the performance of alkali-activated slag tunnel fireproof coatings (AAS-TFC), such as bonding strength, fire resistance, dry density and drying time, etc.was studied.The test results reveal that, when the by weight concentration of sodium hydroxide solution is less than 10%, the bonding strength before and after freezing-thawing cycles and the drying time increase with the increase of the solution concentration, and the drying time decreases with the increase of solution concentration.When the concentration of sodium hydroxide solution is more than 10%, the influence of the solution concentration on the bonding strength, fire resistance, dry density and drying time of AAS-TFC is not obvious.The change of the concentration of sodium hydroxide solution on the fire resistance of AAS-TFC is not obvious.When sodium hydroxide solution concentration was 3%, the performance-to-price ratio of AAS-TFC is the highest.
