Abstract

Mineral admixture is widely used in concretes with less water-cement ratio, to improve some properties like strength and workability. In addition, this admixture has effect on corrosion resistance of embedded re-bars in concrete. In this work, the corrosion rate of mild steel rod, TMT (Thermo Mechanically Treated) rod were observed by adding mineral admixtures in M25 concrete mix. The percentage of admixtures were 3% , the study was carried out for a period of 15 months. The corrosion rates were measured at different intervals by conducting electrochemical tests like ACI test, and by weight loss test (gravimetric method). In most of the time and cases, the corrosion rate was found to be less for 3 % of mineral reducing admixtures. Corrosion resistance of TMT rod is better in the presence of mineral admixtures.
