HIGH STRENGTH CONCRETE COMPOSITION AND MANUFACTURING METHOD OF HIGH STRENGTH CONCRETE CURED BODY
PROBLEM TO BE SOLVED: To provide a high strength cement mortar composition having high compression strength without needs for large scale and special manufacturing facility.SOLUTION: There is provided a high strength concrete composition containing cement, inorganic fine powder, water, a fine aggregate, a coarse aggregate, a water-reducing agent, an antifoam agent and metal fine particles, the cement contains 10.0 mass% to 70.0 mass% of CS and 10.0 mass% to 70.0 mass% of CS, the inorganic fine powder contains silica fume. Also there is provided a manufacturing method of a high strength concrete cured body including a pre-curing process for conducting curing in air at 15 to 25°C for 1 day to 5 days, a primary curing process for conducting curing in water or air at 20 to 60°C for 1 day to 7 days and a second curing process for conducting curing in water or air at 80 to 200°C for 1 day to 21 days.SELECTED DRAWING: None
【課題】大掛かりで特殊な製造設備を必要とせず、高い圧縮強度を有す高強度セメントモルタル組成物を提供することを目的とする。【解決手段】セメントと、無機質微粉末と、水と、細骨材と、粗骨材と、減水剤と、消泡剤と、金属微粉末とを含む高強度コンクリート組成物であって、前記セメントは、Ｃ３Ｓを１０．０質量％〜７０．０質量％及びＣ２Ｓを１０．０質量％〜７０．０質量％含有し、前記無機質微粉末はシリカフュームを含有する、高強度コンクリート組成物である。また、１５〜２５℃の気中で１日間〜５日間養生を行う前養生工程と、２０〜６０℃の水中または気中で１日間〜７日間養生を行う一次養生工程と、８０℃〜２００℃の水中または気中で１日間〜２１日間養生を行う二次養生工程とを含む、高強度コンクリート硬化体の製造方法である。【選択図】 なし
