NUNEZ-JAQUEZ, R.E. et al. Corrosion Evaluation of Modified Reinforcement Concrete by Electrochemical Noise Techniques. Port. Electrochim. Acta [online]. 2005, vol.23, n.1, pp.111-121. ISSN 0872-1904.

The reinforced concrete is a versatile and resistant material and it is used in several construction projects; for this reason the improvement of concrete properties and protection of the reinforced steel against corrosion is an active research area. Diverse methods are applied on the steel or on the concrete to protect them. The present investigation is directed towards the development and performance evaluation against corrosion of the reinforcement concrete, containing two different fly ash and blast furnace slag mixtures, in saline environments, and the corrosive evaluation was performed by electrochemical noise technique. The results show an improvement of the steel reinforcement corrosion resistance.

Palavras-chave : fly ash; slag blast furnace; ternary blend; electrochemical noise.
