PURPOSE: A method for manufacturing cement-free concrete using blast furnace slag is provided to improve the combination density of aggregate and blast furnace slag by adding the optimal amount of a magnesium oxide. CONSTITUTION: A method for manufacturing cement-free concrete using blast furnace slag includes the following: water and an alkaline inorganic material are mixed into the weight ration of 1.5:1 to form a binder(10). 30 to 60 parts by weight of aggregate is mixed with the 100 parts by weight of the blast furnace slag to form a raw material(20). 50 to 80 parts by weight of the raw material and 20 to 50 parts by weight of water are mixed(30). 30 to 40 parts by weight of the binder and 100 parts by weight of water are mixed. 8 to 12 parts by weight of a magnesium oxide is additionally mixed. The mixture is cured.
