CONCRETE STRUCTURE, METHOD OF PRODUCING CONCRETE COMPOSITION, AND METHOD OF CONSTRUCTING CONCRETE STRUCTURE
To provide a method of producing a concrete composition that can be easily molded without sacrificing fluidity of the concrete composition and exhibits excellent workability when porous carbon of high water-retentivity and high adsorptivity such as bio-charcoal is used as an admixture of the concrete composition, and a concrete composition produced by the method.SOLUTION: A method of producing a concrete composition comprises a step of preparing a surface modified charcoal material by allowing a liquid to stick to the surface of a charcoal material, and a step of preparing a composition for concrete by mixing the surface modified charcoal material and a mixture including cement and water.SELECTED DRAWING: Figure 2
【課題】バイオ炭のような保水性及び吸着性が大きい多孔質の炭をコンクリート組成物の混和材とし使用される場合に、コンクリート組成物の流動性を損なわず容易に成形でき作業性に優れたコンクリート組成物を製造する方法、及びその方法により製造されたコンクリート組成物を提供する。【解決手段】炭材料の表面に対して液体を付着させ、表面改質炭材料を調製する工程と、表面改質炭材料とセメント及び水を含む混合物とを混合させコンクリート用組成物を調製する工程を含む、コンクリート組成物の製造方法。【選択図】図２
