As regards efficient use of fly ash a measure is required. However, characteristics of concrete using blast-furnace slag cement and fly ash are less well understood. In this study, the examinations were carried out in order to the effects of drying shrinkage and equivalent characteristics of concrete using blast-furnace slag and fry ash. As a result, concrete using fly ash as fine aggregate comparable in drying shrinkage strain and crack breadth to using blast-furnace slag cement only. In Case of concrete using fly ash as cement were fewer cracks than blast-furnace slag cement. And can be effectively used for preventing chloride penetration into concrete, but cannot be effective for preventing more progress of the neutralization.
