PROBLEM TO BE SOLVED: To provide a concrete composition which can treat rubble which interfere with reconstruction and can prolong life of a reinforced concrete structure obtained even by using an aggregate containing a large amount of salt content which cannot intrinsically be employed in reinforced concrete or by using sea water as milling water.SOLUTION: Provided are (1) a concrete composition containing an aluminosilicate containing lithium and using sea water as milling water, (2) the concrete composition according to (1) containing as an aggregate concrete debris generated as a damage of an earthquake and tsunami, and (3) the concrete composition according to (1) or (2), where a chloride ion content of the concrete is 0.4 kg/mor more. |
