查询词典 air force

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.

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。
