SULFURIC ACID-RESISTANT CEMENT HARDENED BODY
PROBLEM TO BE SOLVED: To provide a sulfuric acid-resistant cement hardened body that can secure the acid resistance of the cement hardened body, reduce the thickness of a skeleton cross section, and reduce the production cost at the same time.SOLUTION: A sulfuric acid-resistant cement hardened body comprises a mortar layer 20 formed of a mortar material comprising a cement binder predominantly composed of blast furnace slag, and a reinforcement material 12 buried in the mortar layer 20. The innermost peripheral surface of the mortar layer 20 is treated with sulfuric acid to form a dihydrate gypsum-made barrier layer 21 integral with the mortar layer 20.SELECTED DRAWING: Figure 1
【課題】セメント硬化体の耐酸性の確保、躯体断面の薄肉化、及び製造コストの低減を同時に達成できる、耐硫酸セメント硬化体を提供すること。【解決手段】高炉スラグを主体とするセメント系結合材を含むモルタル材料で形成したモルタル層２０と、モルタル層２０に埋設した補強材１２とを有し、モルタル層２０の最内周面を硫酸処理してモルタル層２０と一体の二水石膏製のバリア層２１を形成する。【選択図】図１
