Abstract
Concrete is easily affected by material segregation because it is composed of several materials (such as cement, water, aggregate, etc.) that have different properties. Material segregation greatly affects the durability of concrete due to steel corrosion. Since steel corrosion in concrete is an electrochemical process, therefore, acceleration of the electrochemical reaction depends on temperature. However, there are only few researches dealing with above subjects. Therefore, the objectives of this paper are as follows; (1) to evaluate the influence of material segregation on concrete property, (2) to evaluate the influence of material segregation on corrosion rate of steel bar in concrete and (3) to evaluate the temperature dependency of corrosion rate of steel bar in concrete affected by material segregation.
