DUCTILITY OF HIGH PERFORMANCE CONCRETE BEAMS USING SANDSTONE AGGREGATES

Due to brittle nature, the extensive use of High Performance Concrete (HPC) in flexural members has been limited. An attempt has been made to improve the ductility using crushed sandstone coarse aggregate and partial substitution of crushed sandstone sand as fine aggregate. Tests on the ductility b...
