<p>Many concrete deck slabs of bridges have been deteriorated by heavy traffic, and freezing and thawing action. The water through the broken waterproof layer promotes the deterioration of concrete much more. Concrete used in replacements should have high resistance against freezing and thawing attack and fatigue in water. In this study, it is shown that the resistance to freeze and thaw attack can be improved by granulated blast furnace slag sand even without AE agent. The resistance to freeze and thaw attack of non-AE concrete with granulated blast furnace slag is almost same as that of AE concrete with the ordinary crushed sand. The fatigue of concrete suffered from freeze and thaw attack depends on the type of binder. When the crushed sand is used, the fatigue of concrete with high early strength Portland cement suffered from freeze and thaw attack is lower than that with ordinary Portland cement. When blast furnace slag sand is used, the tendency is almost same as when crushed sand is used. However, when blast furnace slag sand is used, the fatigue of concrete suffered from freeze and thaw attack can be improved with water curing period. It is also shown in this paper that blast furnace slag sand reacts with water and improve the durability of concrete.</p>
