【 摘 要 】

In this paper, the performance of concrete with organic inhibitor and slag on compressive strength, chloride penetration resistance and half-cell potential were studied for different water/binder (w/b) ratios and different curing ages. Organic inhibitor (Amines) was admixed with cement during the manufacturing process itself of the cement named as corrosion resistance cement (CRC). The influence of this cement on compressive strength was studied over different curing ages such as 7, 28, 56, 90, 180 and 360 days. Rapid chloride penetration test (RCPT) was conducted to explore the resistance to chloride penetration. Half-cell potential was observed for the period of one year as a measure of corrosion tendency of reinforced concrete (RC) exposed to 3%, 5% and 7.5% of sodium chloride (NaCl) solutions. The results of the concrete with inhibitor (CRC) were compared with the concrete with Portland slag cement (PSC). Significant improvement was observed in compressive strength with increase in curing ages. The performance of CRC concrete shows remarkable improvement in corrosion potential (delayed corrosion initiation) as compared to PSC concrete.
