HYDRAULIC COMPOSITION AND CONCRETE STRUCTURE
To provide a hydraulic composition having excellent workability, capable of being easily installed without losing fluidity, even without adding a large amount of water, when a porous charcoal material having large water retention and adsorption properties, such as biochar, is included in a hydraulic composition, such as a concrete composition.SOLUTION: A hydraulic composition according to an embodiment of the present invention comprises a carbon-containing compact, a hydraulic material, and a chemical admixture as a cement dispersant. The carbon-containing compact has an alkali metal or alkaline earth metal component. The carbon-containing compact is a substantially cylindrical pellet having a long diameter D and a height H. A ratio (H/D) of the height H to the long diameter D is 0.5 or more and 5 or less, and the long diameter D is 1 mm or more and 20 mm or less.SELECTED DRAWING: Figure 1
【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材料をコンクリート組成物などの水硬性組成物に含有させる場合に、多量の水を加えなくとも流動性を損なわず容易に打設できる作業性に優れた水硬性組成物を提供する。【解決手段】本発明の実施形態における水硬性組成物は、炭素含有成形体、水硬性材料、及びセメント分散剤としての化学混和剤を含み、炭素含有成形体は、アルカリ金属又はアルカリ土類金属成分を有する。炭素含有成形体は、長径Ｄ及び高さＨを有する略円柱状のペレットであって、長径Ｄに対する高さＨの比（Ｈ／Ｄ）は、０．５以上５以下であり、長径Ｄは、１ｍｍ以上２０ｍｍ以下である。【選択図】図１
