Flexural Capacity of Singly Reinforced CRC Beams(Part-I)
Crumb rubber concrete (CRC) is made by adding rubber crumbs into conventional concrete, and many studies show that ultimate compressive strains for CRC are much bigger than those for conventional concrete. This article undertakes a mechanical analysis of a reinforced beam based on a proposed CRC stress-strain relationship. The results show that, assuming identical geometrical and material conditions, CRC beam can support more external moment than what conventional concrete beams can do.
