配制高性能混凝土最有效的几种组分是超塑化剂、粉煤灰或矿渣、硅粉。
The most effective ingredients for making up high performance concrete are super-plasticizing agent, fly ash or slag powder, silicon powder.
在水泥颗粒表面的吸附是超塑化剂分散作用的开始，也是其作用的基础。
The adsorption of superplasticizer on cement particle is the be-ginning of dispersion , and it is also foundation of its function.
但是，他们并未对单个超塑化剂分子在水泥颗粒表面的吸附形态提出看法。
Molecules of superplasticizer can adsorb on cement particles in disordered state. This changes physicochemical properties of particle surface.
混凝土达到高性能最重要的技术手段是使用复合超塑化剂和超细矿物质掺合料。
The most important technical means to make concrete with high performance is to use composite superplasticizer and super fine mineral admixture.
超塑化剂主要是大量吸附在水泥颗粒表面的水化产物上而不是吸附在未水化水泥颗粒表面。
Superplasticizer mainly absorbs on the cement hydrates covering the surface of cement particles instead of on the surface of unhydrated particles.
但是人们对其作用机理的研究还比较薄弱，这对超塑化剂的开发、生产以及应用是不利的。
But there is little study on its mechanism, and this is disadvantageous for its invention, production and application.
最后，作者应用吸附点理论对不同掺量超塑化剂对水泥净浆流动性的影响做了较为详尽的解释。
At last , the author exlains the effect of superplasticizer with different dosage on cement paste fluidity with principles of adsorption point at large.
随着高分子合成化学和高分子设计理论不断取得新的进展，成为高性能超塑化剂领域的研究热点。
Now with the development of polymer chemistry and polymer synthesis design theory, polycarboxylic superplasticizers have been the hotpot of the concrete superplasticizers.
