| Abstract: | The expansion value of alkali-aggregate reaction for recycled fine aggregate and natural sand is determined by alkali-acid test methods, and the characteristics and causes of the two alkali-aggregate reactions are analyzed. It is found that the recycled fine aggregate has different characteristics from natural sand. |
