(57) The present invention relates to concrete with necessary durability using seawater and sea sand. The seawater mixed concrete of the present invention is obtained by mixing a mixture including slag-containing cement and sea sand, with seawater. And by including a nitrite-based admixture and pozzolan, the diffusion coefficient of concrete after hardening can be reduced to restrain the external intrusion of harmful factors. Further, the concrete structure according to the present invention can...
