| Abstract: | The effect of admixtures on expansion rate of mortar rod was studied by the fast mortar rod method.The effect of filling silica fume and lithium salt in mortar rod on restraining alkali-aggregate reaction was also studied.The result indicates that mixing right amount silica fume and the lithium salt into mortar may suppress the sample's expansion caused by alkali-aggregate reaction. |

| Keywords: | alkali-aggregate reaction expansion rate admixture |
