混凝土表面防水处理与氯离子隔离层的建立

介绍了3种有机硅防水剂在混凝土表面上的防水处理试验；对防水剂渗透深度进行了多方面比较研究，由此制定出防水剂渗透深度的应用标准，或对具体的防水处理要求给出了相应的防水剂用量；对经不同防水处理及未经防水处理的混凝土进行吸水对比试验，比较不同防水处理方法的效果；将混凝土与海水持续接触28d，检测渗透到混凝土中的氯离子分布．

Water Repellent Treatment of Concrete Surface and Establishment of Chloride Barrier

Comparative studies of the penetration depth while using three different water repellent (agents) on four types of concrete were presented. Based on the study results, criteria to obtain a (required) penetration depth were formulated. An appropriate application technique to have the necessary amount of water repellent agent absorbed by a given concrete quality was also indicated. Water absorption of concrete treated with three different water repellent agents was determined. Untreated and (water) repellent treated concrete samples were exposed to saline water for 28 d. Then the chloride profiles were determined experimentally.
