air entrainer 中文意思是什麼
air entrainer
解釋
加氣劑-
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 )
從混凝土收縮的基本理論? ?毛細管張力理論出發，通過道路混凝土外加劑對水的表面張力的影響研究發現，減水劑對水的表面張力的影響很小，而減縮劑和引氣劑可以大幅度降低溶液的表面張力，溶液的表面張力隨外加劑的摻量呈非線性形式降低，而且都存在臨界膠束濃度。 -
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
通過對選定的引氣劑和減縮劑對硬化混凝土的收縮性能的影響研究發現，引氣劑和減縮劑可以大幅度降低混凝土毛細孔中溶液的表面張力，對降低混凝土收縮具有顯著作用，當二者復摻時，減縮效果更為明顯。
