Abstract: PURPOSE: A slag cement composition is provided to substitute cement for slag powder to improve economic efficiency, salt-tolerance, chemical resistance, and long-term compressive strength and to mix sodium sulfate, desulfurization gypsum, and anhydrous gypsum to obtain initial compressive strength. CONSTITUTION: A slag cement composition comprises the following: 35-50 parts by weight of slag powder, 3.5-8 parts by weight of Natrii sulfas, and 1-10 parts by weight of desulfurization gypsum based on 100.0 parts by weight of normal Portland cement. Two to ten parts by weight of anhydrous gypsum based on 100.0 parts by weight of normal Portland cement are mixed. The manufacturing method of the slag powder comprises the following steps. A pretreatment solution is prepared by mixing a stimulant with water. The pretreatment solution is sprayed on a blast furnace slag, and the blast furnace slag is pulverized. The stimulant contains at least one among hydrogen peroxide, aluminum sulfate, and sodium thiosulfate. Five to ten parts by weight of the stimulant based on 100.0 parts by weight of water are mixed.
