| 摘 要： | 通过改善骨料的级配并建立粉煤灰掺量与水胶比之间的关系,优化粉煤灰混凝土的配制技术。以配制C30混凝土为例,试验结果表明:采用该技术配制的粉煤灰混凝土抗压强度发展与普通硅酸盐水泥混凝土相当,且具有更优异的抗渗透性能。

| Abstract: | The method and results of study on optimization for proportioning of fly-ash concrete are presented by improving aggregate grading and establishing the relationship between fly-ash content and water colloid ratio. It was shown by an example of concrete with C30 that development of compressive strength of fly-ash concrete was similar to normal cement concrete and its penetration resistance was better than that of the latter. |

| Keywords: | fly-ash concrete aggregate grading water colloid ratio penetrability |
