| 钢纤的保养与掺量检验 Maintenance and Dosage Testing of Steel Fiber 钢纤维的保养:钢纤维硅表面湿润不少于7d，时间越长越好，用湿的草袋铺在表面或用养护材料。钢纤维转换梁保养时避免接触风、太阳、雨水等，应对施工梁体进行挡风 Maintenance of steel fiber: The surface of steel fiber silicon is wet for not less than 7 days. The longer the time, the better. Spread it on the surface with wet straw bags or use maintenance materials. When maintaining steel fiber transfer beam, avoid contact with wind, sun, rain and so on. Wind-proof should be carried out for construction beam body. 、防雨等封闭处理。对于钢纤维转换梁，拆模时间应严格控制在达到规范规定的混凝土28d强度之后。如果遇冬季施工，可按常规办法采取防冻措施。 Closed treatment such as rainproof. For steel fiber transfer beams, the demoulding time should be strictly controlled after the concrete strength of 28d specified in the code is reached. If winter construction occurs, anti-freezing measures can be adopted according to conventional methods. 钢纤维掺量检验: Testing of steel fiber content: (1)钢纤维的掺量在硅浇注地点取样检验，每一工作班至少检验二次，每次取三组样品，每组样品为1OL。 (1) The content of steel fibers is sampled and tested at the silicon pouring site. At least twice in each working class, three groups of samples are sampled at a time, each group of samples is 1OL. (2)通过水洗法检验，将钢纤维从硅中洗出，晒干后称量，单个取样钢纤维含量偏差 (2) The steel fibers are washed out of silicon and weighed after drying, and the content deviation of single sample steel fibers is detected by water washing method. 不得超过配比掺量的20%，每三个取样以上钢纤维含量平均值的偏差不得超过配比掺量的5%。 The deviation of the average content of steel fibers per three samples or more shall not exceed 5% of the proportion. |
