| 摘 要： | 本文在提出新拌水泥基复合材料离折行为的三个层次统一模型的基础上,对从流变学角度难以评价的与材料离析直接相关的水泥浆保水特性进行了研究,提出了水泥浆保水能力的临界值,并对不同配合比、各种外加剂以及掺加方法对保水能力的影响进行了试验考察,其结果对丰富新拌混凝土理论及实际工程应用非常有益。

| Abstract: | This paper brings up a united model of three levels about segregation of fresh cement-based composite materials, studies the water retentivity of cement-paste,which is in direct connection with material segregaion and is too difficult to be appraised on rheology. The critical value of Water retentivity of cement-paste is suggested and the experiments on the various mix proportion, all kinds of admixtures and mixing method on water retentivity have been condueted. The result is of value to enrich the thecry of fresh concrete as well as to be used in engineering pratice. |
