随着外加剂技术的日趋成熟以及新型钢纤维的出现,钢纤维混凝土在国际上,特别在欧美发达国家有较大规模的应用,并且这种趋势正在逐年增长。在美国钢纤维混凝土用量为混凝土总量的3%以上。 With the mature of admixture technology and the emergence of new steel fiber, steel fiber concrete in the world, especially in European and American developed countries have large-scale applications, and the trend is increased year by year. In the United States more than 3% of the total dosage of steel fibre reinforced concrete for concrete. 钢纤维混凝土试件在中国自七十年代始才逐渐得以推广应用。随着我国经济建设的不断发展,八十年代、九十年代建设浪潮的不断掀起,钢纤维混凝土的用量也逐年增长。 Steel fiber reinforced concrete specimens in China since the seventy s to be popularized. With the continuous development of economic construction in our country, in the eighty s and eighty s wave of construction of continuous wave, the dosage of steel fibre reinforced concrete is also increased year by year. 上海于1993年底从德国引进了专用技术及成套设备,开始生产哈瑞克斯钢锭铣削型钢纤维,它是直接从高质量的钢锭上,用装硬质合金的旋转铣刀一次铣削完成,产品的横截面为三角形,具有一个粗糙面和一个光滑面,径向扭曲,两端带有锚钩,这种钢纤维长径比为30~45。由于它特有的粗糙表面,与混凝土基体粘结较为牢固,施工性能良好,即使掺量至120kg/m3,也不会结团,可象普通混凝土一样,用预拌与泵送施工。 Shanghai from Germany at the end of 1993 introduced a special technology and complete sets of equipment, to start producing ha, ingot milling steel fiber, it is directly from the high quality ingot, using the rotation of the carbide cutter milling finish at a time, the product of cross section for the triangle, has a rough surface and a smooth surface, the radial distortion, ends with a hook, the steel fiber length to diameter ratio is 30 ~ 45. Because of its special rough surface, and the concrete substrate binding is relatively strong, good construction performance, even if the content to 120 kg/m3, also won't cluster, can be like normal concrete, with premixed and pumping construction.
