<p>The present invention provides a concrete structure having heavy weight and improved corrosion resistance, wherein the concrete structure has specific gravity of 3-4 and is molded by melting and mixing 60 to 90 wt% of steel slag balls, 8 to 30 wt% of a modified sulfur binder, and 1 to 10 wt% of inorganic powdery fillers. The concrete structure can be applied to a marine concrete structure which requires heavy weight like a tetrapod, an artificial reef, and a submarine cable cover to prevent corrosion. The concrete structure is more heavier than an existing concrete structure, is not easily corroded by salt water, and is environmentally friendly.</p> |
