-
Vibration viscosity coefficient of fresh concrete with additives and mineral admixtures are tested. the results show that water reducer and air entrainer can reduce vibration viscosity coefficient while shrinkage - reducing agent has very small influence on it. proper quantity of citric acid, sodium glucaonate or carboxymethy cellulose can reduce vibration viscosity coefficient of fresh concrete
通過對選定的引氣劑和減縮劑對硬化混凝土的收縮性能的影響研究發現,引氣劑和減縮劑可以大幅度降低混凝土毛細孔中溶液的表面張力,對降低混凝土收縮具有顯著作用,當二者復摻時,減縮效果更為明顯。
