ABSTRACT
This study is to classify the rocks in Hualien and Mugua Rivers. There are different rations rock types in Hualien and Mugua Rivers which we collected. We can make sure that the aggregates in Mugua River without andesite, but there are few andesites in Hualien River.
As we knew that in north of pier Hualien maybe caused destroyed by alkali-aggregate reaction, we use ASTM C227 and ASTM C1260 test method to test the reaction and to check which type of rocks may cause this reaction. We found that marble, quartz and metadibase didn''t have the alkali-aggregate reaction, but andesite had the reaction. For the other types of rocks we will still need more study.
Studying on the pessimum value of andesite in Hualien River, and compared with andesite and porphyritic andesite in Baishoulien , we found that : porphyritic andesite in Baishoulien had biggest potential in this reaction; which in Hualien River were middle; in Baishoulien were the smallest.
Pessimum value study in single rock type can use Al2O3, standard sand, Hoping limestone, and metadibase in north of pier Hualien to be the non-reactive aggregates.
In ASTM C1260 and ASTM C227 test method ,we use the aggregates in Hualien and Mugua River replace of Hoping limestone, and found that the more aggregates in Hualien and Mugua River , the more degree of expansion. The degree of expansion increase with the reactive aggregates increase
