大面积钢纤维施工需要注意的地方
大面积钢纤维施工过程中，要保证搅拌均匀，因为钢纤维两端带钩，不容易控制，所以一定要合理配合，搅拌合理。重点是控制好地坪的平整度及防止开裂。
In the process of large area steel fiber construction, it is necessary to ensure uniform mixing, because the steel fiber ends with hooks are not easy to control, so we must cooperate reasonably and mix reasonably. The key point is to control the levelness of the flat and prevent cracking.
在拌合物中加入的钢纤维应充分分散均匀，才能在混凝土中起到增强作用，如果加入的钢纤维分散不均匀，不但没起到增强作用，还会引起局部强度削弱。只要保证钢纤维在拌合料中分散均匀，才能获得良好的增强效果。
The steel fibers added in the mixtures should be fully dispersed evenly so as to play a reinforcing role in concrete. If the steel fibers are not uniformly dispersed, they will not only not play a reinforcing role, but also cause local strength weakening. As long as the steel fibers are evenly dispersed in the mixture, good reinforcement effect can be obtained.
影响钢纤维在拌合料中分散均匀性的因素主要有：钢纤维的体积率、长径比、碎石粒径、水灰比、砂率、以及搅拌机械、投料方法等
The main factors affecting the uniformity of steel fiber dispersion in mixtures are: volume ratio of steel fiber, length-diameter ratio, particle size of gravel, water-cement ratio, sand ratio, mixing machine and feeding method, etc.
施工时应严格按照试验室设计的配合比下料，采用强制式搅拌机拌合，可先投入砂、石、水泥、钢纤维进行干拌，也可以先投入砂、石、水泥、水，在拌和过程中分散加入钢纤维的方法，不管哪种方式都要保持钢纤维分布均匀，提高只用效率。

During construction, it is necessary to cut materials strictly according to the mix proportion designed by jiashan.37ix.com.cnyinyue.37ix.com.cnpailou.37ix.com.cngongcheng.37ix.com.cnyuanlin.37ix.com.cn
shumiao.37ix.com.cnthe laboratory and mix them with a forced mixer. Sand, stone, cement and steel fibers can be put into dry mixing first. Sand, stone, cement and water can also be put into mixing first. The method of adding steel fibers dispersedly in the mixing process should be adopted. Either way, the distribution of steel fibers should be kept uniform and the efficiency of using only steel fibers should be improved.
