Abstract
Corrosion is a serious problem faced in reinforced concrete, which is a crucial component in most of our country's buildings. Therefore, this study aims to evaluate the effect of using silica fume in 28 Mpa concrete on the corrosion rate and compressive strength. The method involved testing concrete with silica fume as a substitute for cement using the SNI 03-2843-2000 standard. Corrosion process was accelerated by applying electric current using the impressed current method on the steel reinforcement in the concrete. Two variations with the highest compressive strength were selected for corrosion testing. The research results showed that the addition of 3% silica fume increased the concrete's compressive strength. However, using more than 6% silica fume significantly decreased the concrete's quality. Corrosion testing revealed that adding silica fume reduced the weight loss of iron due to corrosion, and the higher the percentage of silica fume, the lower the weight loss of iron. Concrete with 3% silica fume experienced a weight loss of 4 grams and a corrosion rate of 1.45 x 10-9 μm/year, while (sample BN) had a weight loss of 5.1 grams and a corrosion rate of 1.9 x 10-9 μm/year. Using 3% Silica Fume in concrete provided a good combination of increased compressive strength and corrosion resistance.
