| 用于建筑工业的钢纤维一般选用碳钢冷拉剪断型纤维。具有无需加抗锈剂.防腐剂等优点。并能提高预制件的性能2-6倍，可代替或减少钢筋用量，缩短钢筋加式制作时间，提高机械化施工程度，可达到普通施工施工方法无法达到的效果，比如抑制屋顶开裂，涵洞漏水等。 用于高速公路面桥梁.水泥枕木.防爆仓库.核实验场，火箭发射场预制应力的混泥土构件等。 隧道窑台面，电厂锅炉个烟道，以及其他有严重急冷急热，机械功能冲击的易裂磨条件下使用耐火料衬里和预制件。 Carbon steel cold-drawn shear fibers are generally used for steel fibers in construction industry. It has the advantages of no need of antirust and preservative. It can also improve the performance of prefabricated parts by 2-6 times. It can replace or reduce the amount of reinforcing steel, shorten the production time of reinforcing steel, and improve the degree of mechanized construction. It can achieve the effect that ordinary construction methods can not achieve, such as restraining roof cracking, culvert leakage and so on. Used for highway surface bridges, cement sleepers, explosion-proof warehouses, nuclear test sites, precast stress concrete components of rocket launching sites, etc. Refractory linings and prefabricated parts are used on tunnel kiln countertops, boiler flues of power plants, and other fragile and abrasive conditions with severe quench, heat and mechanical impact. 钢纤维混凝土加入钢纤维能够有效地阻碍混凝土内部微裂缝的扩展及宏观裂缝的形成，显着改善了混凝土的抗拉、抗弯、抗冲击及抗疲劳性能。在钢纤维混凝土中外加防水剂，具有防潮、阻裂、耐磨等优点，对地下室及人防工程的防水潮起到良好的作用。还可以用在地下水泵防水等钢纤维混凝土是在普通混凝土中掺入乱向分布的短钢纤维所形成的一种新型的多相复合材料。 Steel fiber reinforced concrete (SFRC) can effectively prevent the expansion of micro-cracks and the formation of macro-cracks in concrete, and significantly improve the tensile, flexural, impact and fatigue properties of concrete. Adding waterproofing agent to steel fiber reinforced concrete has the advantages of moisture-proof, crack-proof and wear-resistant. It plays a good role in waterproof tide of basement and civil air-proof engineering. It can also be used in groundwater pump waterproofing and other steel fiber reinforced concrete is a new type of multi-phase composite material formed by mixing short steel fibers randomly distributed in ordinary concrete. |
