钢纤维混凝土是在普通混凝土中掺入定量钢纤维而形成的可浇筑、可喷射成型的一种新型复合材料。它是近些年发展起来的一种性能优良且应用广泛的复合材料。钢纤维在混凝土中主要是限制混凝土裂缝的扩展,从而使其抗拉、抗弯、抗剪强度较普通混凝土有显着提高,其抗冲击、抗疲劳、裂后韧性和耐久性有较大改善,使原本属于脆性材料的混凝土变成具有一定塑性性能的复合材料。 Steel fiber reinforced concrete is a new type of composite material which can be poured and sprayed by adding quantitative steel fibers into ordinary concrete. It is a composite material with excellent performance and wide application in recent years. The steel fiber is mainly limited to the expansion of concrete cracks in concrete, so that the tensile, bending and shear strength of the concrete are greatly improved, and its impact resistance, fatigue resistance, crack toughness and durability have been greatly improved, so that the concrete that belongs to the brittle material becomes a composite material with a certain plastic property. 国际上于上世纪70年代研究开发两端带弯钩、粘结成排钢纤维,目前欧美国家早已进入钢纤维取代钢筋加固混凝土的普及阶段,国内对该材料的认识比较晚。中国的钢纤维技术起步远远晚于国外市场。近几年,随着中国城镇化进程的不断推进,对于公共设施和商业地产项目的投资持续增加,人们对于工程的要求越来越高,于是钢纤维作为一种全新型的建筑材料在地坪工程中脱颖而出。随着中国城镇化进程的不断推进,对于公共设施和商业地产项目的投资持续增加。全球不断的技术创新以及对环境保护意识的全面增长,进一步拉动了购物中心、体育场等商业和公共建筑施工和设计方对新技术和新材料的需求。各类场所都进一步推动新建筑材料和技术的应用和发展。 In the 70s of last century, the research and development of the two ends with crooked hook, bonded steel fiber, now the European and American countries have already entered the stage of steel fiber reinforced concrete reinforcement, the domestic understanding of the material is relatively late. China's steel fiber technology is far behind the foreign market. In recent years, with the continuous progress of the process of urbanization in China, the investment in public facilities and commercial real estate projects has continued to increase, and the demand for engineering is becoming more and more high. So steel fiber, as a new type of building material, stands out in the floor project. With the continuous progress of China's urbanization process, investment in public facilities and commercial real estate projects continues to increase. The global technological innovation and the overall growth of the awareness of environmental protection have further promoted the demand for new technologies and materials by commercial and public buildings, such as shopping centers, stadiums, and other public buildings. All kinds of sites will further promote the application and development of new building materials and technologies.
