STRENGTH PROPERTIES OF ULTRA HIGH EARLY STRENGTH STEEL FIBER REINFORCED ROLLER COMPACTED CONCRETE FOR PAVEMENTS

Toru SUZUKI, Hiroji KOSEKI, Hiroshi ISHIKAWA, Ryosuke TAKAHASHI and Hidenori HAMADA

This report discuss about early age strength of ultra high early strength steel fiber reinforced roller compacted concrete which were combined ultra high early strength concrete and steel fiber reinforced roller compacted concrete. The consistency of ultra high early strength steel fiber reinforced roller compacted concrete and standard roller compacted concrete are equivalent. As for the curing time which reaches mix strength is shortened by 1/6-1/9 as compared with standard RCCP. We clarified early age strength for ultra high early strength steel fiber reinforced roller compacted concrete as compared with ultra high early strength steel fiber reinforced concrete with slump.
