air entraining admixture

In order to solve this problem, different strength grades of concrete which are in common used in hydraulic engineering are prepared by use of local materials and air entraining admixture, and the cross experiment method is adopted.

为研究解决这一工程问题，采用正交试验设计方法，就当地混凝土材料和引气剂设计了几种水利水电工程中常用的不同强度等级混凝土。

Performances of permeability resistant, corrosion resistant as well as compressive strength of the concrete mixed with water reducing agent ( G), air entraining admixture ( Y) and micro aggregate ( H)( GYH concrete) were studied by experimental detecting.

通过实验检测了减水剂（G）、引气剂（Y）、微细集料（H）复合添加配制的混凝土的抗渗、抗蚀及部分强度性能。

The technical characteristic of a new air entraining admixture ( HPS) consisting of alcamines polyatomic copolymer as main composition and trace foam stabilizer as well as property comparison between same type of products at home and abroad are presented.

介绍了一种主要成分由醇胺类的多元共聚物及微量泡沫稳定剂组成的新型引气剂HPS的技术特性及与国内外同类产品的性能比较。

The results show that air entraining admixture and shrinkage-reducing admixture can decrease surface tension of water and Ca ( OH) 2 solution observably. Water-reducing admixture can reduce surface tension of water but has no notable effects on surface tension of saturation calcium hydroxide solution.

研究表明，引气剂、减缩剂可以大幅降低水及饱和Ca（OH）2溶液的表面张力，减水剂可以降低水的表面张力，但在饱和石灰水中表面活性碱弱。

The reasons that air entraining admixture is not widely used in China are discussed in brief and the influence of air entraining admixture on every property of concrete is described.
