| 摘 要： | 模网混凝土在使用过程中出现面层砂浆开裂、钢模网锈蚀的现象。主要通过材料复合的方法，在普通水泥砂浆中加入聚合物形成聚合物水泥砂浆，提高普通砂浆的柔韧性和抗渗能力，并将改性砂浆作为模网混凝土的保护层保护内部钢模网不受锈蚀。

| Abstract: | In the using process of formwork concrete,corrosion was found in the formwork and the cement mortar layer was found cracked.In this paper,the author uses the principle of material complex and adds polymer latex to the ordinary mortar forming PMM which takes the place of the conventional mortar as the surface coated of formwork concrete.It can improve the cracking proof feature and permeability to protect the formwork from corrosion and finally to enhance the durability of formwork concrete. |
