The Effect of Silane-Type Surface Penetrants to Control Scaling and Salt Damage of Highway Bridge Wheel Guard Concrete in Cold Region

摘要

1. Water absorption was less coated area than uncoated area.rn2. The silane-type surface penetrants help delay of scaling progress,rnalthough trends vary by s kind of materials.rn3. The silane-type surface penetrants have ability to greatly retardrnchloride ion supply.rn4. According to this research, the silane-type surface penetrants canrnhelp lower the maintenance cost of wheel guard for 100 year servicernby 15-60%.
