There still persist, however, some doubts about the most appropriate strategy to define the optimum composition of a self-compacting concrete (SCC) mix, based on a required performance. The behavior of SCC as a structural material can be improved if adequate steel fiber reinforcement is added to SCC mix composition.

Self-compacting concrete has to have a high flowability and ability to fill the gaps of reinforcement and corners of molds without vibration. The composition of self-compacting concrete (SCC) has a significant impact on his properties so mix design criterions are mostly focused on the type and mixture proportions of the constituents. In this work, a designe method for SCC proposed by Nan Su ...
