Paper Title:
Experiment and Analysis of Flexural Strength for Shrinkage-Compensating Steel Fiber Reinforced Shotcrete
  Abstract

The flexural strength of shotcrete which prepared for cementitious material incorporated with cements,accelerating agents and expensive agents is studied.By changing the fraction of steel fibers by volume and the addition percentage of expensive agent in binding material,the influence on flexural strength of the two factors is investigated,the mechanism of steel fibers and expensive agents work together to reinforce the shotcrete and the strength development law are analyzed.The result shows that, the flexural strength of steel fiber reinforced shotcrete is improving with the volume fractions of steel fibers increasing.And the flexural strength of shrinkage-compensating shotcrete is decreasing with the addition percentage of expensive agent in binding material adding except 6%. The flexural strength of shotcrete is rather better when the fraction of steel fibers by volume is 1.2%~1.6% and the addition percentage of expensive agent in binding material is 8%,which indicates that the restriction effect of steel fibers can enhance the flexural strength of shrinkage-compensating shotcrete,embodies the effect of synergistic enhancement and compounding effect with steel fibers and expensive agents.
