Mix proportioning of self-compacting high- and ultra-high-performance concretes with and without steel fibres Available to Purchase

A method is proposed for proportioning self-compacting high- and ultra-high-performance concrete mixes without steel fibres (SCHPC/SCUHPC) and with steel fibres (SCHPFRC/SCUHPFRC) which meet the standard flow and passing ability criteria without segregation. This method is based on an extensive investigation of the flow characteristics of self-compacting concrete (SCC) mixes using computational simulations. It provides an alternative tool to the heuristic mix design of SCC, thus avoiding expensive and time-consuming tests in laboratories or on site.
