Abstract:
Eight mixtures of sulfur concrete and three mixtures of portland cement concrete were studied comparatively for reinforcing steel corrosion. The reinforced specimens were partially immersed in 5 percent sodium chloride solution for a period of 2 years and were subjected to corrosion measurements. The test results indicate that the time to corrosion initiation of reinforcing steel in sulfur concrete is longer than that in portland cement concrete. But, once the corrosion initiates, the corrosion rate of reinforcing steel in sulfur concrete is higher than that in a good-quality portland cement concrete.
