| 摘要: |
| 采用氧扩散法测定了砂浆的渗透性，用于评估硬化水泥石的开放孔隙率及研究混凝土的耐久性．结果表明，砂浆试件的氧扩散法测定结果能正确地反映水灰比、胶凝材料组成和养护条件等对水泥石孔结构和渗透性的影响；砂浆渗透性与其抗硫酸盐性能有很好的相关性． |

| Abstract: |
| By measuring the permeability of mortar specimens with an oxygen diffusion equipment, the open porosity of hardened cement paste(hcp) was evaluated and the durability of concrete was discussed in this research. The research shows that the results of measuring oxygen diffusion can correctly reflect and reveal the effects of some factors such as water cement ratio, composition of cementitious materials, curing condition on the pore structure and permeability of hcp. There is a good relativity between the permeability and the sulfate resistance of mortar. |
