摘要

The use of HSC in civil infrastructure is increasing due to the various advantages compare to normal strength concrete. Normal strength concrete (NSC) is the most commonly used type of concrete in construction projects and is suitable for a wide range of applications. High strength concrete (HSC) is the term used for concrete mixes, which possess invariably high strength, high dimensional stability, reasonable workability and high durability. This type of concrete finds application in heavily reinforced sophisticated structural elements in high rise buildings, off-shore platforms, super span bridges, prestressed concrete members and heavy-duty pavements. This study examines the behavior of normal strength concrete beam and high strength concrete beam subjected to torsional moment. For this purpose, 12 specimens of 150 mm × 300 mm cross- section with a length of 1500 mm were cast. The specimen were tested for torsion. The torsional moment and twist of angle were noted. Failure at first crack and ultimate points are observed. In both cases, HSC and NSC initial crack and ultimate failure in the controlled beam were developed earlier as compared to the beam designed for torsion. In some cases, HSC may be more attractive as a structural material than NSC if torsional moment is taken into account.
