| 1. | Synthesis and property of superplasticizer of polycarboxylate series 聚羧酸系超塑化剂的合成及性能研究 |
| 2. | Performance of shrinkage - reducing and anti - cracking concrete superplasticizer and its action mechanism 减缩抗裂型混凝土超塑化剂的性能及其作用机理 |
| 3. | The way in improving their compatibility is therefore put forward based on the aforementioned results 据此,提出了生产与超塑化剂相适应性好的水泥的途径。 |
| 4. | Several questions about the compatibility of superplasticizer with cement for ready - mixed concrete are discussed from the standpoint of cement chemistry 从水泥化学角度讨论了预拌混凝土用的水泥与超塑化剂相适应性的几个问题。 |
| 5. | Superplasticizer mainly absorbs on the cement hydrates covering the surface of cement particles instead of on the surface of unhydrated particles 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。 |
| 6. | 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 水泥与超塑化剂相适应性不好主要是水泥水化产物吸附大量的超塑化剂所致。 |
| 7. | This article describes the due properties of high - performance concrete , the high - performance concrete that should be developed and popularized in china , the application of super - plasticizer and the technical measures to be taken in preparation of high - performance concrete with super - plasticizer 介绍了高性能混凝土应具有的性能,在我国应开发和推广的高性能混凝土,超塑化剂的应用,以及使用超塑化剂配制高性能混凝土时应掌握的技术措施。 |
| 8. | Factors which can accelerate the early hydration of cement , the setting in particular , such as excessively high c3a content , too low so3 content , high alkali content and the blending of pozzolana with large inner specific surface area , etc . , will result in poor compatibility of the superplasticizer with cement 凡是加速水泥初期水化的因素,特别是使水泥凝结加速的因素如c3a含量过高、 so3掺量过少、碱含量高以及掺入内比表面积大的火山灰质混合材等均使水泥与超塑化剂的相适应性变差。 |
