The effect of temperature and salt contamination on corrosion of reinforcing steel in ordinary portland cement and blended cement concretes.

摘要

This study was conducted to investigate the effect of relatively high temperatures (25 to 70;The Cl;The reinforcement corrosion activity, in both the OPC and blended cement concrete specimens was observed to be higher in specimens contaminated with both chloride and sulfate salts as against those contaminated with only chloride salts. At 70;Results indicated that both the temperature and chloride-sulfate contamination influence the compressive strength of OPC and blended cement concrete specimens.
