| Abstract | ||
| Reactive powder concrete has superior mechanical and structural properties but the major drawback of this new construction martial is its high cost. This research presents experimental study to investigate flexural behavior of hybrid tee beams and study the ability of using normal strength concrete together with RPC in the same section to exploit the advantages of these two materials in optimal way. The experimental results showed that using RPC in the web and normal strength concrete in the flange effectively enhanced performance of hybrid T-section beams when compared with normal strength concrete T-beam, however, the increases in the first crack load, ultimate flexural load and ultimate deflection were 86.67%, 60% and 29.19% respectively, while, the increases for the case of using RPC in the flange and normal strength concrete in the web were 20%, 34.28% and 14.97 respectively when compared with normal strength concrete T-beam | ||
