HIGH-STRENGTH POROUS CONCRETE COMPOSITION AND HIGH-STRENGTH POROUS CONCRETE CURED BODY
PROBLEM TO BE SOLVED: To provide a porous concrete composition or the like, which can achieve high water permeability and high strength, and has improved compaction property.SOLUTION: A high-strength porous concrete composition contains at least a coarse aggregate, a fine aggregate, water, a water-reducing agent, and the following binder, where a water-binder ratio is 10 to 20%, a ratio of mortar coarse aggregate gap is 0.35 to 0.95, and a ratio of a paste fine aggregate gap is 1.0 or more. The binder is a mixture containing pozzolanic fine powder having a BET specific surface area of 15 to 25 m/g, fly ash having a Blaine specific surface area of 2,500 to 10,000 cm/g, anhydrous gypsum having a Blaine specific surface area of 3,000 to 12,000 cm/g, and Portland cement or common eco-cement.SELECTED DRAWING: None
【課題】本発明は、高透水性かつ高強度を実現でき、さらに締固め性が向上したポーラスコンクリート組成物等を提供する。【解決手段】本発明は、粗骨材、細骨材、水、減水剤、および、下記の結合材を、少なくとも含む高強度ポーラスコンクリート組成物であって、水結合材比が１０〜２０％、モルタル粗骨材空隙比が０．３５〜０．９５、および、ペースト細骨材空隙比が１．０以上である、高強度ポーラスコンクリート組成物である。結合材：ＢＥＴ比表面積が１５〜２５ｍ２／ｇのポゾラン質微粉末、ブレーン比表面積が２５００〜１００００ｃｍ２／ｇのフライアッシュ、ブレーン比表面積が３０００〜１２０００ｃｍ２／ｇの無水石膏、および、ポルトランドセメントまたは普通エコセメントを含む混合物【選択図】なし
