ADSORPTION PERMEABLE CONCRETE
PROBLEM TO BE SOLVED: To provide a paving concrete having a water permeable property to which a function of fixing carbon dioxide in an atmosphere in an adsorptive manner is applied.SOLUTION: An adsorption permeable concrete comprised of an adsorptive material and a polymeric binder mixed together having a function of adsorbing water, cement, coarse aggregate, carbon dioxide, is characterized in that natural zeolite is used as the adsorption material and is mixed with the coarse aggregate at a volume ratio of 15% to 50%, water permeability coefficient of cured concrete is 1.0×10cm/sec or more. In order to improve tensile strength, it is preferable that high-performance AE water-reducing agent is added at 2% with respect to the mass of the cement.SELECTED DRAWING: Figure 5
【課題】 浸透透水性を有する舗装用コンクリートに、大気中の二酸化炭素を吸着固定させる性能を付与する。【解決手段】 水、セメント、粗骨材、二酸化炭素吸着性能を有する吸着材、ポリマー系バインダーを配合してなる吸着透水性コンクリートであって、前記吸着材として天然ゼオライトが使用され、前記粗骨材に対して容積比１５％〜５０％で混合され、硬化後のコンクリートの透水係数が１．０×１０-1ｃｍ／ｓｅｃ以上とすることを特徴とする。引張強度増加を図るために高性能ＡＥ減水剤を前記セメント質量の２％添加することが好ましい。【選択図】図５
