通过自制的试验装置测试混凝土和砂浆的内部相对湿度、水分质量损失和徐变，研究了掺加不同外加剂和矿物掺合料的水泥基材料中水迁移对徐变的影响。结果表明，不同减水剂和复合功能组分对混凝土内部相对湿度和徐变度有不同影响；不同细度石英砂粉对掺有硅灰的水泥基材料的内部相对湿度或水分质量损失以及徐变度有较大影响；加载状态并未引起水泥基材料内部相对湿度或水分质量损失的变化；水泥基材料内部相对湿度或水分质量损失结果与其徐变度之间没有对应关系。

The internal relative humidity, water loss and creep of concrete and mortar were tested by the self-made test device, and the effect of water migration of cementitious materials with the different addtives and mineral admixtures on creep was studied in order to understand the role of water in the creep process. The results indicate that the effect of different water reducing agent and composite functional components on internal relative humidity and specific creep of concrete is different, the effect of different fineness quartz powder on water loss or internal relative humidity and specific creep of cementitious materials with silica fume is obvious, the loading status does not cause the change of water loss or internal relative humidity of cementitious materials, there is not the corresponding relationship between water loss or inter-nal relative humidity and specific creep of cementitious materials.
