A Study on the Shrinkage Reducing Properties of Steel Fiber Reinforced Ultra High Strength Cement Mortar
강섬유보강 초고강도 시멘트 모르터의 수축저감에 관한 연구
- Published : 2005.11.01
Abstract
Ultra high strength concrete, nowadays, has been widely applied to construction of high-rise building. To improve ductility and mechanical properties, steel fiber is employed in UHSC. This study investigates practical application of expansive additives(EA) and shrinkage reducing agent(SRA), in order to secure volumetric stability and improved mechanical properties, such as autogenous shrinkage and dry shrinkage of steel-fiber-reinforced-ultra-high-strength-comet-mortar(FHSM). According to the test, individual addition of steel fiber does not affect shrinkage reduction, as expected. However FHSM, with combined addition of 5
