#60 Special Concretes | Self Compacting Concrete | Segregation & Laboratory Tests

Welcome to 'Admixtures and Special Concretes' course ! This lecture focuses on segregation issues in self-compacting concrete (SCC) and introduces various laboratory tests used to assess its properties. It emphasizes the importance of proper mix design to prevent segregation. The lecture discusses slump-based tests, including the slump flow test, which measures the flowability of SCC. It introduces the U-Tube and V-funnel tests, which evaluate both flowability and the ability of SCC to pass through obstacles, simulating reinforcement congestion in real-world applications.
