气垫膜养护法是利用太阳能养护混凝土直接覆盖式的一种。它与自然养护法相比,能缩短养护周期、节约养护用水,操作简便、构件养护质量好。适用于露天生产混凝土构件厂养护混凝土。用这种方法养护混凝土构件,在每年5～10月间,养护周期由自然养护的6～8天缩短到2～3天,而在11～4月间可从8～12天缩短到4～5天;构件强度可比自然养护提高5.4%;而且能降低养护成本28%,节约养护用水,若与蒸汽养护相比,则可降低成本60～90%。且能节
The air-cushion film maintenance method is one that utilizes solar energy to directly cover concrete. Compared with the natural conservation method, it can shorten the maintenance cycle, save water for conservation, and has simple operation and good quality of component maintenance. Applicable to the open-air production of concrete components plant curing concrete. In this way, the concrete components are preserved. From May to October each year, the maintenance period is shortened from 6 to 8 days of natural maintenance to 2 to 3 days, and from November to April, it can be shortened from 8 to 12 days to 4 to 4. 5 days; the strength of the components can be increased by 5.4% compared with the natural conservation; and the maintenance cost can be reduced by 28%, and conservation of water can be saved. If compared with steam curing, the cost can be reduced by 60 to 90%. And energy section
