| 摘要: |
| 建立了表征混凝土渗流结构的4个参数，根据这4个参数随水化时间发生的变化，可以了解水泥浆全和普通混凝土的水化过程，在掺加高炉矿渣和粉煤灰后，因其不同的水化机理和水化过程，混凝土的渗流结构发生了变化。可以通过研究矿物掺合料对混凝土渗流结构的影响来了解矿物掺合料的水化过程，并为工程实践中选择合适的掺合料及其适当掺量提供参考。 |

| Abstract: |
| The percolation structure of concrete is characterized by four parameters, i.e. the hydraulic radius r h, the tortuosity T , the resistance of charge transfer R ct and the capacitance of double layer C . From the change of these parameters with time, the hydration process of cement paste and concrete can be learned. Upon adding mineral blend to concrete, the percolation structure will change from which the function of mineral blend in the concrete can be learned. |
