| 摘 要： | 为了研究高C3S水泥硬化浆体水浸取液中离子浓度与水化条件间的关系，本文利用水浸取法探讨了水化时间、水灰比、水化温度等因素对高硅酸三钙水泥水化硬化体系水浸取液中离子浓度的影响。试验结果表明：浸取液中的各离子浓度和pH值随水化时间的延长、水灰比的增加和养护温度的升高而降低；其中水化14d前离子浓度和pH值下降速度很快，14d下降速度趋缓；各水化条件下离子浓度的大小主要与水化程度、孔隙率和水化产物的溶解相关。该研究对于从离子浓度方面去了解高C3S水泥的水化特点具有一定的指导意义。

| Abstract: | In this paper,the effect of the hydration time,the ratio of water to cement and the hydration temperature on the ion concentrations in water extraction solution of high C_3S cement paste has been investigated by water extraction method.The result show that ion concentrations decrease with the duration of the hydration time,the increase of the ratio of water to cement and the rising of the hydration temperature.The ion concentrations decrease considerably 14 days before hydration,but decrease gently 14 days ... |
