Mechanical Behavior of Refined SCC with High Admixture of Hybrid Micro- and Ordinary Steel Fibers

The addition of steel fiber to self-consolidating concrete (SCC) may considerably prolong cracking time and improve its deforming performance. Current studies mainly apply high content micro-steel fibers the mechanical performance SCC whilst assuring workability, however, there are still very few concerning influence a mixture with ordinary on SCC. Thus, this paper conducted experimental ordinary-sized hybrid reinforced (MOSCC). Plain (PSCC), (MSCC), (OSCC) proposed for comparison MOSCC in respects workability Test results show that highly enhance compressive strength, flexural ductility as well maintaining workability. This provides reference improvement material enhancement crack resistance structures.
