Abstract |
There is possibility of poor-state concrete filling condition due to segregation of aggregate and paste in reinforced concrete structure. This study was conducted to evaluate the flexural and shear behavior of reinforced concrete beams with different concrete filling conditions. Different concrete filling conditions were intentionally made such that the specimens was soundly cast to obtain the perfect concrete filling condition and cast in such a way that up to the longitudinal tensile reinforcement from the top, good concrete was filled while poor concrete was poured for the bottom part to simulate the poor strength, workability and unsatisfactory compaction. The test results indicate that have no effect of concrete filling conditions on the yielding strength of structures. But, have a great influence on the flexural ductility and shear capacity of structures.
