钢纤维混凝土出现于本世纪初,到70年代初期,美国研制成功了熔钢押丝法生产钢纤维,为钢纤维混凝土的实际应用铺平了道路,目前美、日、英等国发展较快。我国70年代开始研制钢纤维混凝土,80年代以来已在多处工程中试用。大连造船新厂扩建工程是国家重点项目,因此在基建过 Steel fiber reinforced concrete emerged in the beginning of this century, and in the early 1970s, the United States successfully developed the steel production method of molten steel, which paved the way for the practical application of steel fiber reinforced concrete. Currently, the United States, Japan, Britain and other countries have developed rapidly. . In the 1970s, China began to develop steel fiber concrete. Since the 1980s, it has been tested in many projects. The Dalian Shipbuilding Plant Expansion Project is a national key project and therefore has
