REDUCTION MATERIAL, PRODUCTION METHOD THEREOF, CEMENT COMPOSITION, AND SOIL IMPROVER
To provide a reduction material capable of reducing occurrence of granular floating matters on a surface of slurry when being formed into the slurry.SOLUTION: There is provided a reduction material including sulfur particles, a Ca-containing object, and a reaction product of them. In the reduction material, with a total amount of the sulfur particles, a Ca-containing object, and reaction product of them as a reference, a dissolution ratio of the sulfur particles, a Ca-containing object, and reaction product to water in a prescribed condition is 3 mass% or greater. The reduction material may satisfy the following formula (1). The formula (1) is WLRa≥(WLS×RS+WLCa×RCa)/(RS+RCa)+0.5. In formula (1), WLRa, WLS, and WLCa indicate, respectively, the dissolution ratio of the reduction material, the sulfur particles before reaction, and the Ca-containing object before reaction to water under the prescribed condition, and RS and RCa respectively indicate a molar ratio of the sulfur particles before reaction and the Ca-containing object before reaction.SELECTED DRAWING: None
【課題】スラリーとしたときにスラリーの表面に生じる粒状の浮遊物を低減することができる還元材を提供すること。【解決手段】硫黄粒子、Ｃａ含有物及びこれらの反応生成物を含み、硫黄粒子、Ｃａ含有物及び前記反応生成物の総量を基準としたときの、所定条件下における硫黄粒子、Ｃａ含有物及び反応生成物の水への溶解比率（ＷＬＲａ）が３質量％以上である、還元材を提供する。この還元材は、下記式（１）を満たしてよい。ＷＬＲａ≧（ＷＬＳ×ＲＳ＋ＷＬＣａ×ＲＣａ）／（ＲＳ＋ＲＣａ）＋０．５・・・（１）上記式（１）中、ＷＬＲａ、ＷＬＳ及びＷＬＣａは、それぞれ、所定条件下における、還元材、反応前の硫黄粒子、及び反応前のＣａ含有物の水への溶解比率を示し、ＲＳ及びＲＣａは、それぞれ、反応前の硫黄粒子と反応前のＣａ含有物のモル比を示す。【選択図】なし
