摘要: In this paper, applications of the methods ASTM G16 for addressing inherent conflicts in laboratory measurements corrosion test data were studied, using inhibiting effect NaNO2 on concrete steel-rebar case study. For this, electrochemical monitoring techniques employed studying effectiveness different concentrations admixture replicated samples immersed NaCl and H2SO4 media an experimental period sixty-eight days. The from setup subjected to probability density fittings Normal Weibull functions as well significance testing G16-99 R04 specifications. Results identified 10g (0.1208M) with optimal inhibition efficiency model, η = 88.38±4.62%, saline/marine simulating environment 8 g (0.0966M) optimum effectiveness, 13.51±83.48%, acidic environment. adequately addressed conflicting admixtures studied environments. joshua.okeniyi@covenantuniversity.edu.ng
