| 摘 要： | 本文针对当前预拌混凝土生产中普遍存在的粉状高掺量防水剂添加计量麻烦，不自动计量，劳动强度高，环境污染大等问题，根据减水塑化、引气抑制泌水、补偿收缩及憎水等防水抗渗机理。采取多种防水性能互补的有效组份优化组合，通过试验研究，研制出了一种防水抗渗性能优良的低掺量(2．5％以下)复合型液体泵送防水剂。

| Abstract: | This test is amid at the general existent problems of the water-repellent admixture use in pump concrete,the powdery and high accretion admixture with many shortcomings,without automatic measure,with high working-intension,with polluted environment and so on.We mixed many water-repellent elements for concrete according as the theory of reduce water,adhibit gas,reduce shrinkage,adding hydrophobe and so on.According the research,we produce a multiple liquid water-repellent admixture for pump concrete with good performance and low accretion(under 2.5%). |

| Keywords: | pump concrete water-repellent low accretion liquid water-repellent admixture for concrete |
