Corrosion-Resistance Characteristics of Concrete Containing Furfural

Corrosion inhibiting admixtures are unique among other methods to protect reinforced concrete from corrosion damage. In this study, the effect of furfural on fresh and hardened properties mixes 35 45 MPa compressive strengths as well inhibition was evaluated. Furfural added at different dosages (1, 2 3% by weight cement) with without superplasticizer (HRWR). Different electrochemical measurements were performed (Half-cell potential, Tafel plot linear polarization resistance). Electrochemical confirmed that dramatically reduces rate corrosion; efficiencies 62.7 63.8 % due addition 45MPa-concretes respectively. Results also showed combined presence HRWR found provide an excellent protection steel.
