PFJ混凝土防水技术研究

Study of PFJ Concrete Waterproof Technique

围绕隧道混凝土渗漏水问题，探讨了木钙、粉煤灰，以及膨胀剂对混凝土抗渗性及其它物理力学性能的影响。在隧道混凝土中科学、合理地运用掺加木钙、粉煤灰及膨胀剂技术，可以配制出优质的防水混凝土，取得显著的技术经济效益。

The influence on unpermeability and other physical and mechanical properties ofconcrete caused by adding wooden calcium, flyash and expanding agent is discussed,so as to scien-tificly and reasonably make use of these three materials to produce high quality-waterproof con-crete.
