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。 -
Mix mineral additive into concrete has great effect on the pore structure, especially the addition of sodium sulfate coarsening the pore structure enormously, and increase the total porosity. after mixing sodium sulfate, the chloride ion diffusion coefficient of air entraining concrete increased, impermeability reduced ; but mixing sodium nitrite and sodium chloride can
Na _ 2so _ 4摻入后，引氣混凝土的氯離子擴散系數增大，抗滲性降低;而nano _ 2和nacl能夠細化水泥石的孔結構，對混凝土的抗滲性有利，但提高幅度不大。
