Salt sea durability is improved so that the endurance life of a marine concrete structure built in a marine environment is significantly increased, the present invention is hardened when mixed with water and portland cement containing calcium oxide, silicon dioxide, aluminum oxide; It has latent hydraulic properties, reduces heat generation during hydration, produces Friedel salts that fix chloride ions during curing, and is mixed to increase long-term compressive strength of hardened concrete and contains calcium oxide, silicon dioxide, aluminum oxide, and magnesium oxide. Blast furnace slag; Fly ash containing silicon dioxide, aluminum oxide, and iron oxide mixed to improve long-term compressive strength and watertightness by pozzolanic reaction while improving processability and curing heat; Reinforced aggregates that are mixed to increase the strength of the cured concrete and include fine aggregates and coarse aggregates; And the Portland cement, the blast furnace slag, the fly ash, and the reinforcing aggregate to disperse the particles of the mixture mixture to provide fluidity and mixed with the admixture so as to suppress corrosion by chloride ions penetrating the concrete salt resistance Provided is a marine concrete composition. |
