Crack Patterns and Measurement Technique in Reinforced Concrete

Abstract

The phenomenon of steel corrosion and concrete crack patterns under different water to cement ratios and cover depths of concrete was investigated. The steel corrosion of single reinforced concrete beam with different admixtures under repeated loading was also studied. It is possible to predict the crack patterns and mechanical behavior of concrete when steel corrosion is induced. The addition of inhibitors was able to reduce the corrosion rate. If concrete undergoes repeated loadings, the resulting crack will allow harmful elements in todal zone to penetrate into the concrete. This will accelerate the corrosion rate, especially at high loading conditions.
