浅析混凝土养护 目前,国内混凝土养护的方法很多,如自然养护、满水法养护、蒸汽养护、箱梁蒸汽养护、养生液养护等,自然养护方法比较普遍采用.但有些施工单位比较忽视混凝土的养护,洒水、覆盖养护不能按规范要求及期限适时进行,且养护质量难以控制与管理,还有养护的温度和时间,根本达不到自然养护要求的标准,不仅影响混凝土早期强度的增长,更重要的是由于混凝土表面水分急剧蒸发失散,造成混凝土表面干缩、龟裂、起毛,严重影响混凝土整体质量以及其他性能的发挥.为了使新浇混凝土及其外露面保持适当湿度,使混凝土具有良好的硬化条件,经反复试验,生产了混凝土养护剂.鉴定与工程应用表明,养护剂养护方法能够保证混凝土体水化反应,真正达到养护标准,较国内目前普遍采用的自然养护方法更具优越性.

According to the concrete curing at present, the domestic concrete curing many methods, such as natural conservation, water conservation, with steam curing, a beam steam curing, and health maintenance, nature conservation liquid method is the universal use. But some construction unit is ignored the concrete curing, spraying, covering maintenance can't according to standard requirement and time limit, the maintenance quality of timely and difficult to control and management, and maintenance of temperature and time, basically could not reach natural maintenance requirements, not only affect the concrete early strength of growth, the more important is due to the concrete surface water evaporation sharply separated, and cause the concrete surface drying shrinkage, cracked, burr, the serious influence concrete whole quality and other properties of the play. In order to make the new site concrete and its outside appearance, make concrete maintain proper humidity has good cure conditions, after the repeated test, the production of the concrete curing agent. Appraisal and engineering application shows that curing agent maintenance method can guarantee concrete hydration reaction and get a true maintenance standards, a domestic widely adopted now natural maintenance methods more superiority.
