清水混凝土是指采用现浇工艺一次成型,且在拆除浇筑模板后不再作外部抹灰等工序,以混凝土自然色作饰面的混凝土施工工艺。清水混凝土的常见病中,泌水引起的水线,以及蜂窝麻面、气孔、黑印尤为突出。聚羧酸盐减水剂具有低掺量、高减水、低收缩、流动性好等特点,使用聚羧酸盐减水剂及其复配技术可以有效地防止清水混凝土的常见病,取得工程中比较满意的效果。
Clear water concrete refers to the use of cast-in-place process once molded, and in the demolition of the pouring template is no longer for the external plastering and other processes to make concrete natural color for the surface of the concrete construction process. Common diseases of fresh concrete, bleeding caused by the water line, as well as honeycomb surface, stomatal, black mark is particularly prominent. Polycarboxylate superplasticizer with low dosage, high water reduction, low shrinkage, good liquidity and other characteristics of the use of polycarboxylate superplasticizer and its compounding technology can effectively prevent the common diseases of fresh water concrete, to obtain engineering More satisfied with the results.
