Abstract
A laboratory study has been conducted on R.C beams with coarse aggregate replaced by pretreated supplementary aggregates and micro-reinforcement included. For this investigation, seven full-scale beams of length 3 m and having a size of 150 mm × 250 mm were fabricated and tested for their strength and ductility. One beam was treated as reference specimen. Remaining six beams were fabricated with pretreated supplementary aggregates and micro-reinforcement. Content of rubber shreds and quantum of micro-reinforcement were considered as the primary variable. The fabricated specimens were tested under monotonic loading until failure. It is evident from test that inclusion of pretreated supplementary aggregates and micro-reinforcement adds the strength and ductility of R.C beams.
