air entrainer meaning in English
加气剂
加气器
起泡剂
Examples
- Based on the theory of shrinkage , capillary force theory , the influence of road concrete additives in common use on surface tension of water is studied , and the results show that the influence of water reducer is very small whereas shrinkage - reducing agent and air entrainer can reduce surface tension of solution significantly . the relation between surface tension and additive dosage are non - linear relation . each additive has an obvious critical micelle concentration ( cmc )
从混凝土收缩的基本理论? ?毛细管张力理论出发,通过道路混凝土外加剂对水的表面张力的影响研究发现,减水剂对水的表面张力的影响很小,而减缩剂和引气剂可以大幅度降低溶液的表面张力,溶液的表面张力随外加剂的掺量呈非线性形式降低,而且都存在临界胶束浓度。 - Vibration viscosity coefficient of fresh concrete with additives and mineral admixtures are tested . the results show that water reducer and air entrainer can reduce vibration viscosity coefficient while shrinkage - reducing agent has very small influence on it . proper quantity of citric acid , sodium glucaonate or carboxymethy cellulose can reduce vibration viscosity coefficient of fresh concrete
通过对选定的引气剂和减缩剂对硬化混凝土的收缩性能的影响研究发现,引气剂和减缩剂可以大幅度降低混凝土毛细孔中溶液的表面张力,对降低混凝土收缩具有显著作用,当二者复掺时,减缩效果更为明显。
