| 钢纤维砼表面湿润不少于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、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。 The surface of steel fiber reinforced concrete is wet for not less than 7 days. The longer the time, the better. Use wet straw bags to spread on the surface or use curing materials. When the steel fiber transfer beam is maintained, it should avoid contact with wind, sun, rain and so on. The construction beam body should be closed for wind and rain protection. 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. |
