Abstract: The purpose of this study is to establish the mixing procedure of steel fiber reinforced concrete that can be mixed uniformly by a ordinary concrete mixer, even if the volume fraction of steel fiber with more than 2% is designed. The mixing procedure examined in the experiment is as follows : 1) The observed volume fraction of steel fiber at mixing is reduced by entraining the air in a base concrete under usage of the forming agent 2) The air content in a steel fiber reinforced concrete is reduced by using the erasing agent at the final step of mixing. It was found from the experiment that the limiting volume fraction of steel fiber increases according to the addition quantity of forming agent, because the slump of steel fiber reinforced concrete with same mix proportion increases remarkably by adding the forming agent. Consequently, the mixing ability of steel fiber reinforced concrete can be improved by using forming and erasing agents.
