Key Points

This research investigates the impact of curing conditions on the chloride penetration state and its effects on the scaling resistance of mortar under freeze-thaw conditions.
Systematically varied curing conditions such as immersion duration, drying period, drying temperature, and saturation treatment.
Conducted freeze-thaw testing under chloride solution based on JIS A 5022 Appendix D guidelines.
Measured the scaling resistance correlated with the depth of chloride ion penetration.
Found a negative correlation between chloride ion penetration depth before freeze-thaw action and scaling amount.
As curing conditions improved penetration depth, scaling damage decreased significantly.

Examines how chloride solution penetration influences mortar scaling resistance, suggesting optimal curing conditions.
