在地下防水工程应用 UEA 过程中,我们发现 UEA 虽有很多优点,但要是不懂它的特性,施工后也很难做到工程不渗不漏。只有充分发挥 UEA 的优点,了解它的特性并精心施工,才能取得满意的效果。一、使用 UEA 后产生渗漏的原因UEA 膨胀剂的优点这里不多叙述,但也应注意到它在生产过程中掺有使混凝土坍落度损失过快的材料,所以在混凝土里加 UEA 膨胀剂,坍落度损失很快。这也就使得没有充分的时间来处理好混凝土的接槎,容易产生硬接槎的现象,在该处构成漏水、渗水的隐患,使混凝土的抗渗抗漏能力大
During the application of UEA in underground waterproof projects, we found that UEA has many advantages, but if it does not understand its characteristics, it will be difficult to make the project invisible after construction. Only by giving full play to the advantages of UEA, understanding its characteristics and carefully constructing it can achieve satisfactory results. First, the cause of leakage after using UEA The advantages of UEA expansion agent are not described here, but it should also be noted that it incorporates in the production process materials that cause the concrete slump loss to be excessive, so UEA expansion agent is added to the concrete. The slump loss is very fast. This also results in insufficient time to properly handle the concrete joints, and it is prone to hard joints. This poses hidden dangers of water leakage and water seepage, making the concrete impervious to anti-leakage.
