dc.description.abstract	This paper reports the results of a study on the corrosion of high strength concrete with silica fume subjected to 15% concentration of sulphuric acid, hydrochloric acid and lactic acid. Silica fume were used to replace 8% and 15% of the cement, by weight. The results showed that partial replacement of cement with silica fume had no effect on lactic acid resistance, improved the hydrochloric acid resistance and worsened the sulphuric acid attack. Sulphuric acid attack resulted in concrete disintegration at an almost constant rate, the hydrochloric attack rate was reduced with time, whereas the lactic acid attack resulted leaching of corrosion products, at a slower rate under stagnant condition.	en_US

Abstract:

This paper reports the results of a study on the corrosion of high strength concrete with silica fume subjected to 15% concentration of sulphuric acid, hydrochloric acid and lactic acid. Silica fume were used to replace 8% and 15% of the cement, by weight. The results showed that partial replacement of cement with silica fume had no effect on lactic acid resistance, improved the hydrochloric acid resistance and worsened the sulphuric acid attack. Sulphuric acid attack resulted in concrete disintegration at an almost constant rate, the hydrochloric attack rate was reduced with time, whereas the lactic acid attack resulted leaching of corrosion products, at a slower rate under stagnant condition.
