Underground concrete with high impermeability and durability
The invention provides underground concrete with high impermeability and durability. Comprising the following components in parts by weight: 50 parts of cement, 100-110 parts of coarse aggregate, 1.2-1.5 parts of polycarboxylate superplasticizer, 74-76 parts of modified machine-made sand and 7-10 parts of water swelling rubber doped with silica powder. According to the invention, the water-swelling rubber doped with silica powder is used as a filler and is used for underground concrete, the underground concrete is always in a wet state, and the water-swelling rubber doped with silica powder can adsorb and swell when encountering water to fill pores in the concrete and block a formed permeation channel, so that the anti-permeability effect is achieved; the water-swelling rubber is also doped with silica powder, and along with the adsorption of water, the silica powder overflows from the water-swelling rubber into the concrete and fills a gap between the set cement and an interface transition area, so that the interface structure between the water-swelling rubber and the set cement is improved, and the material structure is more compact; and a possibly formed permeation channel is further blocked.
本发明提供了一种地下高抗渗耐久性混凝土。包括以下组分：水泥50份、粗骨料100‑110份、聚羧酸减水剂1.2‑1.5份、改性机制砂74‑76份、掺有硅微粉的吸水膨胀橡胶7‑10份。本发明采用掺有硅微粉的吸水膨胀橡胶作为填充物，用于地下的混凝土，常处于潮湿状态，掺有硅微粉的吸水膨胀橡胶遇水可以进行吸附，同时膨胀，将混凝土中的孔隙进行填充，阻断形成的渗透通路，从而达到抗渗的效果，另一方面，吸水膨胀橡胶中还掺杂有硅微粉，随着水分的吸附，硅微粉会从吸水膨胀橡胶中溢出至混凝土中，填充在水泥石与界面过渡区的空隙中，使吸水膨胀橡胶与水泥石之间的界面结构得到改善，材料结构更为致密，进一步阻断可能形成的渗透通路。
