Performance of shrinkage - reducing and anti - cracking concrete superplasticizer and its action mechanism 減縮抗裂型混凝土超塑化劑的性能及其作用機理
Study of adsorbability of cement for superplasticizer with different clinker modulus and mineral composition 熟料率值及礦物組成不同的水泥對高效減水劑吸附性能的研究
By measuring surface tension , adsorptive content and potential of the superplasticizer solution , the mechanism was studied 4 。而添加磺甲基化產物的砂漿因較長時間的緩凝,強度有所下降。
When the amount of cement is equal , the main reason affect the compatibility of the system is the kinds of superplasticizer and its amount 當水泥一定時,外加劑的品種和摻量是影響體系相容性的主要原因。
Several questions about the compatibility of superplasticizer with cement for ready - mixed concrete are discussed from the standpoint of cement chemistry 從水泥化學角度討論了預拌混凝土用的水泥與超塑化劑相適應性的幾個問題。
Superplasticizer mainly absorbs on the cement hydrates covering the surface of cement particles instead of on the surface of unhydrated particles 超塑化劑主要是大量吸附在水泥顆粒表面的水化產物上而不是吸附在未水化水泥顆粒表面。
To resolve the slump - loss of the concrete adding superplasticizers and get better performance , a new superplasticizer , polyaminobenzenesuflate ( hp ) was developed 以主導官能團理論為基礎,探討了高效減水劑的組成與性能之間的關系。
The major reason for the occurring of nonconformance between cement and superplasticizer lies in the fact that large amount of superplasticizer is absorbed by hydrates 水泥與超塑化劑相適應性不好主要是水泥水化產物吸附大量的超塑化劑所致。
Superplasticizers, also known as high range water reducers, are chemicals used as admixtures where well-dispersed particle suspension are required. These polymers are used as dispersants to avoid particle aggregation, and to improve the flow characteristics (rheology) of suspensions such as in concrete applications.
