| description | PROBLEM TO BE SOLVED: To provide a method of reducing the drying shrinkage of concrete, which does not use a limestone aggregate and nonetheless obtains an effect equal to or above an effect obtained by using the limestone aggregate, and to provide a method of producing concrete. SOLUTION: Each of the method of reducing the drying shrinkage of concrete and the method of producing concrete comprises: a step of mixing cement, fine aggregate including blast furnace slag fine aggregate, coarse aggregate and water; and a curing step of curing the kneaded matter to obtain concrete, wherein the water absorption rate of the fine aggregate of the blast furnace slag is 0.1 to 1.5 mass%.
