LIGHTWEIGHT CONCRETE HARDENED BODY, LIGHTWEIGHT CONCRETE COMPOSITION AND METHOD FOR PRODUCING LIGHTWEIGHT CONCRETE HARDENED BODY
To provide a lightweight concrete hardened body having improved crack resistance and carbonation resistance, excellent in durability, a lightweight concrete composition capable of obtaining a lightweight concrete hardened body excellent in durability, and a method for producing the lightweight concrete hardened body.SOLUTION: Provided are a lightweight concrete hardened body, a lightweight concrete composition, and a method for producing the lightweight concrete hardened body, which is a hardened body of a kneaded body including a lightweight coarse aggregate impregnated with a compound represented by an expression (I), cement, a fine aggregate, and water. In the expression (I), RIA is a hydrogen atom or a hydrocarbon group having 1-30 carbon atoms, RIB is an alkylene group having 1-5 carbon atoms, IC is an integer of 1-100, and a plurality of existing RIBO may be the same or different from each other.SELECTED DRAWING: None
【課題】ひび割れ抵抗性及び中性化抵抗性が改良された、耐久性に優れる軽量コンクリート硬化体、耐久性に優れる軽量コンクリート硬化体が得られる軽量コンクリート組成物、及び軽量コンクリート硬化体の製造方法を提供する。【解決手段】下記式（Ｉ）で表される化合物を含浸させてなる軽量粗骨材と、セメントと、細骨材と、水とを含む混練物の硬化体である軽量コンクリート硬化体、軽量コンクリート組成物及び軽量コンクリート硬化体の製造方法。下記式（Ｉ）中、ＲＩＡは水素原子又は炭素数１～３０の炭化水素基であり、ＲＩＢは炭素数１～５のアルキレン基であり、ＩＣは１～１００の整数であり、複数存在するＲＩＢＯは、互いに同じであっても異なっていてもよい。JPEG2024000870000034.jpg991【選択図】なし
