HYDRATED HARDENED BODY

Japanese Patent JP3958090

B2

PROBLEM TO BE SOLVED: To provide a hydrated hardened body lighter in weight than a conventional one even if steelmaking slag is used as the raw material of the hydrated hardened body.
SOLUTION: Granular molten pig pretreatment slag as the steelmaking slag and blast furnace slag fine powder and incinerated ash as an SiO2 containing substance having potential hydraulicity are used for the hydrated hardened body. The blast furnace fine powder has 10-50 mass% content, the incinerated ash has 10-40 mass% content, the molten pig pretreatment slag having ≤1.18 mm particle size has 3-15 mass% and the sum total of the blast furnace slag fine powder and the incinerated ash has >50 mass% and <80 mass% content in mixed raw material except water. One or more selected from the group consisting of oxides, hydroxides, sulfates and chlorides of alkali metal and alkali earth metal and cement are added to the total mixed raw material by 1-10 mass% to the content of the sum total of the blast furnace slag and the incinerated ash.
