| 摘要: |
| 根据地铁工程对混凝土耐久性和抑制电流腐蚀的特殊要求，研制了高阻抗混凝土，结果表明：在粉煤灰混凝土中掺加由矿粉和胶乳组成的复合阻抗剂，并采用特殊的搅拌工艺，可使混凝土的阻抗得到显著提高，从而满足地铁工程的特殊需要。 |

| Abstract: |
| A type of high impedance concrete was prepared to meet the need of metro engineering, in which diminishing the corrosion due to stray current is one of the primary importance. Mineral admixture emulsified by a special gel was used to increase the impedance of the concrete so as to satisfy the requirement of the engineering. |
