Indian concrete journalSummary: In this study, attempts have been made for the use of recycled aggregate in place of normal coarse aggregate in reinforced concrete columns. It includes processing of recycled aggregates and then obtaining their physical and mechanical properties. Both compressive and flexural strength of concrete mixes decrease with increase in the percentage of recycled aggregate added. To analyse compression behaviour of ferrocement confined, reinforced recycled aggregate concrete columns, six column specimens were cast. Out of which, one column from each of the two size-groups is kept as control column, one each is strengthened using ferrocement and the remaining for assessing the effect of retrofitting with ferrocement. It is observed that ultimate strength of confined specimens increased significantly. A comparison with results of two analytical models showed higher ultimate strengths than obtained in the experiments.
