Defects of Conventional Concrete and Developments of Self Compacting Concrete along with its Applications
The obstacles met during the production and construction of High Strength Concrete (HSC) and High Performance Concrete (HPC) are analyzed, then the poly-carboxylate based admixture is studied in detail. After that, presents the trend of using Self Compacting Concrete (SCC) to improve the performance of concrete structures, i.e. its durability and reliability, because its highly flowing nature makes it suitable for placing concrete in difficult conditions and sections, especially with crowded steel reinforcement. Utilization of SCC can also reduce the time required for placing large sections in concrete structures, e.g. in the basement or substructure’s concrete pouring. SCC may also minimize the noises on the construction site that are induced by concrete vibrators. Accompanying the presentation of the performance of SCC, its applications in the recently completed Grand Wisata Cable Stayed Bridge designed by the Authors are also introduced.
