PURPOSE : A manufacturing method of GEO polymer concrete is provided to enhance compressive strength by maximizing use amount of recycled aggregate without using natural aggregate or natural sand. CONSTITUTION : A manufacturing method of GEO polymer concrete comprises the following steps : drying and pulverizing waste concrete powder; preparing GEO polymer powdery raw material by measuring blast furnace slag, fly ash, waste concrete powder and phosphate with respective range of 30 : 55 : 10 : 3-80 : 10 : 5 : 5; pulverizing and mixing the GEO Polymer powdery raw material; manufacturing GEO polymer concrete raw material by mixing 150-500 parts by weight of recycled coarse aggregate with 150-500 parts by weight of recycled fine aggregate based on 100 parts by weight of the GEO polymer powder; obtaining slurry by mixing 30-200 parts by weight of fluid activator with 100 parts by weight of the GEO polymer concrete raw material; molding the slurry into the GEO polymer concrete; and curing the molded GEO polymer concrete.
