Abstract

This paper studies C6H18N4 (Triethylenetetramine; TETA) corrosion-resistance behavior on reinforcing-steel in concreteimmersed in 0.5 M H2SO4. Analyses showed that the corrosion inhibition efficiency increases as theconcentration of C6H18N4 admixture increases, whereby the inhibition efficiency also portrayed excellent correlation model (at r = 98.82%, Nash Sutcliffe Efficiency (NSE) = 97.65%, Analysis of Variance (ANOVA) pvalue = 0.0350) with function of the C6H18N4 concentration admixed in the concrete. The optimal resistance to reinforcing-steel corrosion, in the study, was exhibited in the concrete sample having 0.1824 M C6H18N4 admixture, from which inhibition efficiency η = 94.78% was attained. The results support the suitability of C6H18N4 for inhibiting reinforcing-steel corrosion in concrete for the industrial/microbial medium, simulated by the 0.5 M H2SO4.
