water reducer meaning in Chinese
减水剂
Examples
- Act - fdn varies from common water - retaining plasticizers and complex water reducers ; it does n ' t contain compound retardants and has no bad influence on the early strength of concrete
因为act - fdn并没有复合缓凝成分，它不同于一般的保塑剂或复合型减水剂，突出的特点是对混凝土的早期强度无不利影响。 - The outcome of this paper can be used in determining the effect of water reducer , and lays the foundation for the prediction of concrete slump and the mix proportion design of higher volume - stability concrete
该关系可用于高效减水剂减水率的测定，同时也可为混凝土坍落度的预测及高体积稳定性混凝土配合比设计方法的研究奠定基础。 - 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。 - Abstract : based on composite testing of naphthalene superplasticizer and different retarders as well as retarding water reducer , in which the overall amount of admixture is certain , this paper analyzes the influence of these multicomponent admixtures on flowability of neat cement 、 retarding action and development of strength of colloidal mortar . the result shows that compatibilities of different components are different , and composition effects are also different
文摘:在总掺量一定的情况下，就萘磺酸盐高效减水剂与不同缓凝组分、缓凝型减水剂等复合后对水泥净浆流动度、缓凝作用、胶砂强度发展等性能的影响作用进行了试验分析，结果表明各不同组份复合的相容性不同，复合效应也存在差别。 - 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。
