| 摘 要： | 试验测试了混凝土在常压状态下，不同水泥粒度和水胶比对混凝土渗透性的影响。指出在一定气干条件下，水泥粒度越细，水胶比越低，混凝土在毛细孔压力作用下的渗透性越大。尤其是掺入了超细矿渣的水泥混凝土。这种渗透性的增大更为明显。

| Abstract: | The influence of different cement grain size and W/B ratio to the concrete permeability under the condition of normal atmospheric pressure is tested. It is pointed out that under certain air-dried condition, the cement grain is thinner and the W/B ratio is lower, the concrete permeability is bigger under the function of capillary pressure, and especially when the superfine slag is mixed into the cement concrete, the permeability is increased more obviously. |

| Keywords: | concrete permeability cement grain size W/B ratio capillary pressure |
