Durability and strength variation due to corrosion in RC beams using brick and stone chips Available to Purchase

The study was conducted to find the effect of using brick as a coarse aggregate in reinforced concrete (RC) beams and to obtain optimum replacement ratios without significantly reducing the durability (i.e. corrosion probability in reinforcement and chloride ion resistivity in reinforcement cover) and flexural strength of the specimen subjected to a marine environment. Specimens were exposed to alternate wetting and drying cycles in an artificially prepared corrosive environment (chloride ions with a concentration of 50 parts per 1000). A regression model for finding the overall mass loss in the reinforcement after the effect of corrosion is presented. A regression model to obtain the different fundamental properties of the concrete through replacing stone by brick aggregate is also presented. This regression model was validated using the k-fold validation approach.
