Self Compacting Concrete Structures: A Techno-Economic Analysis

摘要: The concept of self-compacting concrete (SCC) was performed in late 1980 by Japanese researchers as a solution for the lack skilled workers and decreasing quality building industry. high fluidity SCC allows flowing under its own weight, filling completely formwork without any vibration or material segregation, providing higher surface. Since discovery, large number researcher studied rheological properties, adjusted mix design methods analysed mechanical characteristics. placement method conventionally is no more valid SCC, mixture behaviour changed substantially. This aspect less examined published inconsistent, even though it plays an essential role assessment global cost building. aim this study to investigate materials cost, labour requirements, demands, construction time structure using vibrated compare results.
