Abstract
Recently, because of the terrorisms or warfare, the damages of human life or facilities have been increased. Hence, the Korean government launched the research group for high performance fiber reinforced cementitious composite (HPFRCC) with increased demanding on protecting and anti-explosive structures. Therefore, in this research, to apply the HPFRCC on military facilities with optimum performance on workability and performance, the fundamental properties and reduction of autogenous shrinkage of HPFRCC with various combinations of steel and organic fiber and emulsified refined cooking oil (ERCO) were evaluated. As a result, based on the comprehensive analysis, for favorable workability, strength, and autogenous shrinkage, 1.5 % of combined fiber of short steel fiber and long organic fiber and 0.5 % of ERCO was suggested as an optimum conditions.
