SULFURIC ACID-RESISTANT CEMENT HARDENED BODY
PROBLEM TO BE SOLVED: To provide a sulfuric acid-resistant cement hardened body mainly composed of blast furnace slag powder capable of producing in a short time, a solid hardened body having a characteristic of salt damage resistance or acid resistance.SOLUTION: A sulfuric acid-resistant cement hardened body has a multilayer structure comprising internal concrete 15 including a coarse aggregate 11, and a reaction protective layer 16 formed of only a mortar component to be altered to a barrier layer 17 made of dihydrate gypsum when being reacted with sulfuric acid, on a surface layer of the internal concrete 15.SELECTED DRAWING: Figure 2
【課題】耐塩害性、耐酸性の特性を有する密実な硬化体を短時間に製造できる、高炉スラグ粉末を主体とした耐硫酸セメント硬化体を提供すること。【解決手段】粗骨材１１を含む内部コンクリート１５と、内部コンクリート１５の表層に、硫酸と反応すると二水石膏製のバリア層１７に変質するモルタル成分のみで形成した反応保護層１６とによる多層構造とした。【選択図】図２
