STUDY ON INFLUENCE OF MIX PROPORTION ON WORKABILITY OF STEEL FIBER REINFORCED CONCRETE

The conditions of mix proportion steel fiber reinforced concrete were examined to obtain both the required workability and ductility. Under condition amount that unit absolute volume coarse aggregate was 250 L/m3 or more, larger it was, greater decrease in slump caused by mixing fibers velocity passing through obstacles tended be slower. Furthermore, a simple method proposed evaluate resistance against material segregation from quality content each component mortar.
