(57) A cement composition includes a curable component in an amount of 10 to 25 wt. %; a fine aggregate (FA) in an amount of 20 to 40 wt. %; a coarse aggregate (CA) in an amount of 40 to 50 wt. %; and an alkaline component in an amount of 5 to 15 wt. %, each wt. % based on the total weight of the cement composition. The curable component includes a cementitious material having an average particle size (D50) of 10 to 17 micrometers (µm), a limestone powder (LSP) material having a D50 of 13 to 19 µm, a red mud (RM) material having a D50 of 30 to 36 µm, a silicomanganese fume (SMF) material having a D50 of 28 to 34 µm, and a natural pozzolan (NP) material having a D50 of 13 to 19 µm.
