Abstract | Bridge structure in the USA amounted to 577,000 units and as many as 134,000 units (23% of the total bridge) againstÃÂÃÂ damage caused by corrosion. This damage requires repairs at a cost not less than U.S.$ 90.9 billion. This damage is similar to theÃÂÃÂ events in Indonesia.ÃÂÃÂ This research was performed by use of the calcium Stearate to neutralize reinforcement corrosion in reinforced concrete. CalciumÃÂÃÂ Stearate will react with the cement hydration reaction during the process underway. The result of this reaction is physically looksÃÂÃÂ like a candle. This compound would cover and fill the capillaries when water evaporates in the fresh concrete. This layer does notÃÂÃÂ absorb and impermeable to water and corrosive compounds. So that these compounds caused corrosion of the reinforcement can notÃÂÃÂ penetrate reinforced concrete. The ultimate goal of using calcium Stearate is to increase the service life of aging structures inÃÂÃÂ corrosive areas such as building docks, bridges andrigid layer on the highway.ÃÂÃÂ The results showed that the use of calcium Stearate concrete with fly ash at 0% have a tendency of lowering the rate of corrosion ofÃÂÃÂ reinforcement and inhibit corrosion. Calcium Stearate with a dose of 2 kg per m3 of concrete can decrease makrocell valueÃÂÃÂ amounting to 67%. While on the concrete with fly ash 40%, the addition of 2 kg of calcium Stearate cause makrocell value decreasedÃÂÃÂ by 85%. |
