HYDRAULIC COMPOSITION, CURED PRODUCT, AND METHOD FOR PRODUCING HYDRAULIC COMPOSITION
To provide a low-carbon type hydraulic composition that is manufactured using an inorganic mineral other than kaolin and has sufficient compressive strength.SOLUTION: A hydraulic water-curing composition contains 30-70 mass% of inorganic minerals (except kaolin) having SiO2 content of 30-40 mass% and Al2O3 content of 30-40 mass%, and 30-70 mass% of alkali stimulants, and in the inorganic minerals, a ratio of a peak area of at least one of four-coordinated Al and five-coordinated Al is 30-50% when the sum of the peak areas of four-coordinated Al, five-coordinated Al and six-coordinated Al analyzed by 27Al-NMR is 100%.SELECTED DRAWING: None
【課題】カオリン以外の無機鉱物を用いて製造され、かつ十分な圧縮強度発現性を有する、低炭素型の水硬性組成物を提供すること。【解決手段】ＳｉＯ２含有量が３０～４０質量％でありＡｌ２Ｏ３含有量が３０～４０質量％である無機鉱物（但しカオリンを除く）を３０～７０質量％、及びアルカリ刺激材を３０～７０質量％含み、無機鉱物において、２７Ａｌ－ＮＭＲで分析した４配位Ａｌ、５配位Ａｌ及び６配位Ａｌのピーク面積の和を１００％とした時の、４配位Ａｌ及び５配位Ａｌの少なくとも一方のピーク面積の割合が３０～５０％である、水硬性組成物。【選択図】なし
