Abstract:In tests to determine the influence of the quality of mortar and concrete upon corrosion of reinforcement the variables studied were cement content, water-cement ratio, consistancy, grading and depth of cover. The specimens, stored in moist air or exposed to weather, were tested up to the age of two years. The results indicate that consistancy has a pronounced effect upon the protective value of mortar and concrete, and that there appears to exist an "optimum consistancy" at which the quantity of rust is practically uneffected by time. It was also found that the usual cement contenets in reinforced concrete have only a limited effect on corrosion. It is concluded that water-cement ratio does not in itself control the rate of corrosion of reinforcement.
