使用普通硅酸盐水泥混凝土,采用常规洒水覆盖养生时间不得少于7天,且在养生后期混凝土强度增长缓慢,很难满足工程中箱梁预制的需要。本文针对这一问题,简要介绍蒸汽养生在箱梁预制中的应用,并结合实际工程在箱梁预制中,采用了蒸汽养生,有效保证了箱梁混凝土强度,缩短了工期。
The use of ordinary Portland cement concrete, the use of conventional sprinkler cover health time of not less than 7 days, and the slow growth of concrete strength after the health regimen, it is difficult to meet the needs of box girder project. In order to solve this problem, this paper briefly introduces the application of steam curing in box girder prefabrication. Combining with the actual project, steam curing is adopted in box girder prefabrication to effectively ensure the concrete strength and shorten the construction period.
