Development of admixtures with wet curing effects has desired from the improvement of productivity and the labor saving of construction perspective. This study focused on latex used for the polymer cement concrete, and evaluated the influence of the amount of latex on the initial wet curing effect, the durability and the steel bar corrosion when using a small amount of latex. The main findings are: The concrete with latex whose an initial wet curing period was 3 days improved the surface unti-permeability and the mass transfer resistance, and was equal to or better than that of the normal concrete with the initial wet curing period of 7 days. Also the concrete with latex has preventing the macrocell corrosion of the steel bars.
