| 摘 要： | 通过对水灰比分别为0.25、0.30、0.50的混凝土标准养护28d抗压强度和抗渗等级研究,并根据低渗透性混凝土的特点,测量了压力水渗透的深度,利用公式初步估计了混凝土的渗透系数。采用硅灰与高效减水剂双掺的方法,可以制备抗渗透性能极为优异的混凝土。

| Abstract: | The compression strength and impermeability of high strength concrete with W/B ratio of 0.25, 0.30, and 0.50 under standard curing 28 d were studied,and based on the feature of low permeability concrete measured the depth of pressure water penetration,and preliminary estimated permeability coefficient of the concrete making use of expression.Concrete with excellent impermeability can be prepared by adding both silica fume and superplasticizer. |

| Keywords: | high strength concrete silica fume water reducing agent impermeability |
