至于“保湿养护”的时间,不应少于 14d,尤其要关注前 7d 天,这是黄金养护期,而关键是前三天,特别是第一天,这是关键中的关键。因为,混凝土的幼龄期在这一时段是胶凝材料水化最活跃,水化产物生成最多,强度增长最快的时段。但是,如果不注意养护,也是混凝土拌合水丧失最快、最容易产生失水缺陷的时段。有些施工人员却不懂这个道理,为了赶工期,不仅不覆盖,连水也不浇,刚刚终凝就开始放线,接着就吊装钢筋、模板、脚手架,哪顾得上养护?其结果后患无穷,只好花更多的钱、浪费更多的时间去处理渗漏,真是劳民伤财,还使硬化后混凝土的耐久性能大大降低。

对于地下室厚大底板及外墙、剪力墙等结构部位的养护,除了要及时保湿外,还要进行温度控制,要适当保温(覆盖塑料布和麻袋保湿保温),确保混凝土体中心与表层温差以及表层与环境温差都不大于 20℃,要缓慢降温,每天降温不超过 2℃。切记在混凝土体表面温度较高的情况下,不可浇凉水,防止急剧降温,造成较大温度应力,导致混凝土开裂。

盛夏高温季节施工时,砂石可喷洒水雾降温;也可通过计算,以合适的冰霄用量等量取代部分拌合水搅拌混凝土,可以将混凝土的入模温度降低到 30℃ 以下。搅拌车滚筒应适时喷水降温,输送混凝土的泵管应覆盖湿麻袋防晒散热。若条件许可,应避开高温时段浇筑混凝土。混凝土浇筑后,应及时进行保湿保温养护,必要时,可搭盖遮阳棚,防风防晒,减少水份蒸发。

夏季施工的另一个特点是雨水多,有时雨来得很急,很猛。夏季因为气温高,泵送混凝土的坍落度通常较大,但雨季施工时坍落度应尽量小些。低坍落度的混凝土遇雨保浆能力较强,减少雨水冲刷浆体的流失。大雨到来之前应及早作出判断,用塑料薄膜将已振实抹平和未振实的混凝土都予覆盖。有施工单位因为赶不及,只对振实抹平的混凝土进行覆盖,而没有振实的混凝土未予覆盖。笔者认为这是用反了的方法。未振实的混凝土有很多脚印,大雨过后,这些脚印都灌满了雨水,振动之前一般没有排除这些积水,也很难将其排除掉。振动的过程中,雨水融入混凝土,大大加大了水胶比,加之部分浆体流失,对混凝土质量的影响是很大的。笔者向施工单位建议,如果雨水来得快,来不及全部覆盖,首先要覆盖的是未振实的混凝土,对已振实抹平的混凝土,也一定要将周边覆盖好,使薄膜紧贴周边混凝土的表面,防止雨水冲走水泥浆。混凝土快猫网站免费观看免费振实抹平时,最好能将周边略压高一点,让雨水积蓄在混凝土表面。这样做,起到了“即时水养护”的作用。施工单位按此方法做了,效果还是不错的。

综上,在郑州混凝土养护时,也应该注意相关问题,避免出现混凝土养护不当,确保混凝土质量良好。
