CONCRETE COMPOSITION FOR FORMING CARBON DIOXIDE FIXING FORMED BODY, CARBON DIOXIDE FIXING FORMED BODY MADE OF THE COMPOSITION, AND METHOD OF MANUFACTURING THE FORMED BODY

PROBLEM TO BE SOLVED: To provide a concrete composition for forming a carbon dioxide fixing formed body by which the formed body having a feature to effectively fix carbon dioxide in the air is formed without impairing original dynamic properties such as compressive strength or bending strength of concrete, the formed body made of the concrete composition and a method of manufacturing the same. SOLUTION: The concrete composition contains water, cement, admixtures, aggregate, an alkali decomposable resin fine particle or an organic fiber comprising an alkali decomposable resin and fine powder or an adsorbent capable of adsorbing carbon dioxide. The formed body having 0.05-10 volume% void having 10-200μm diameter or cavity hole having the cross section of the same diameter on the surface part is obtained by hardening the concrete composition.
