Ground granulated blast furnace slag by the single micron particle is expected to be used as repair related material for the purpose of improving initial compressive strength. However, it is said that the use of ground granulated blast furnace slag by the single micron particle increases shrinkage of mortar. Therefore, the compressive strength and fresh properties of mortar using ground granulated blast furnace slag by the single micron particle were tested. And, we investigated the possibility of improvement of shrinkage of mortar. As a result, it was found that by using ground granulated blast furnace slag by the single micron particle with the same particle size and small BET specific surface area, compressive strength shows equivalent characteristics and shrinkage of mortar can be improved.
