Evaluation of Various Temperature Levels on the Reliability Index for Reinforced Concrete Members Made of Geopolymer Mixes Subjected to Chloride Concentration

Mostafa Hassan · Journal of Materials Science Research and Reviews · 2026

Chloride-induced corrosion is a major durability concern for reinforced-concrete bridge decks exposed to de-icing salts, and increasing temperature may accelerate chloride transport. This study evaluated the probability of chloride-induced corrosion initiation and the reliability...
