| 钢纤维厂进过近几年的统计,发现城市道路以及国道省道的车辆负荷密度逐渐加大,并且车速越来越快,导致了路面的使用寿命较以前缩短了很多。所以在路面中增加新型复合型钢纤维成完了必不可少的一步。从使用方式上来看,钢纤维不仅适用于路面,还在沿海地区得到了广泛使用。现在钢纤维已经成为了世界各国普遍实用的一种混凝土增强材料。因为钢纤维具有抗裂、抗冲击性,可以进一步提高混凝土的性能。钢纤维在混凝土表面有斜向和纵向两种,整平时应使整平机前的混凝土涌向路面横坡的一侧。收光是使混凝土的表面更加致密、平整、美观。纤维混凝土原材料进厂后,应进行进场检验。在施工过程中,还应对钢纤维混凝土原材料进行抽检。抽检项目应包括抗拉强度、弯折性能、尺寸偏差和杂质含量。在钢线为使用量加大的近几年的时间里,钢纤维厂不仅加大了对钢纤维的生产,还尽最大努力对刚纤维进行改革创新。 In recent years, according to the statistics of steel fiber factories, it is found that the vehicle load density of urban roads and provincial highways is gradually increasing, and the speed of vehicles is getting faster and faster, which leads to a much shorter service life of pavement than before. Therefore, it is an essential step to add new composite steel fibers to the pavement. From the point of view of usage mode, steel fiber is not only suitable for road surface, but also widely used in coastal areas. Now steel fiber has become a common and practical concrete reinforcement material all over the world. Because steel fiber has crack resistance and impact resistance, it can further improve the beijing.89ix.com zhixiang.07858.netdianxiangan.37ix.cn zhoucheng.37ix.cn chongdianzhuang.07858.net langyashan.37ix.com.cnperformance of concrete. There are two kinds of steel fibers on the surface of concrete, inclined and longitudinal. During leveling, concrete in front of leveler should flow to the side of the cross slope of pavement. Daylighting is to make the surface of concrete more compact, flat and beautiful. Fiber reinforced concrete raw materials should be inspected after entering the factory. In the construction process, the raw materials of steel fiber reinforced concrete should also be sampled and inspected. Sample inspection items should include tensile strength, bending property, size deviation and impurity content. In recent years, the steel fiber factory has not only increased the production of steel fibers, but also made great efforts to reform and innovate the steel fibers. |
