 Abstract:             
              Self-compacting concrete (SCC) is a relatively new building material. This material is progressively changing the way concrete is placed on building sites. This text fills a gap in the literature and provides a thorough understanding of the behavior of self-compacting concrete which is far different than traditional concrete.                 Read more...
