摘要： PROBLEM TO BE SOLVED: To provide a treating method for asbestos which makes the treated product recylable stably without dumping the treated material, consuming a great quantity of energy or producing the material which is easy to react with water such as forsterite having a posibility of recrystallization to chrysotile. SOLUTION: The material containing Si, Ca and/or Al is added to and mixed with a material to be treated containing asbestos conforming to the following condition, and the obtained mixture is heat-treated at 400 deg.C to 1,200 deg.C. Addition conditions: The mol ratio of Mg to Si in the material to be treated is adjusted to Mg/Si =1.3, the material containing Al is added so as to make Al2 O3 mass percentage >= ((Ca/Si)×0.357-0.464)×100.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing calcium silicate hydrate slurry characterized by the addition of barium chloride and/or aluminum chloride in the method for producing calcium silicate hydrate slurry by hydrothermal reaction with a calcareous raw material and a siliceous raw material as the main raw materials, to provide calcium silicate hydrate slurry produced by the method, and to provide a calcium silicate molding obtained by using the calcium silicate hydrate slurry as the raw material.
SOLUTION: The calcium silicate hydrate slurry can be produced in a state where sulfate ions are almost absent, and, the calcium silicate hydrate slurry which has a low bulk density, and exhibits excellent lightweight effect can be obtained. Then, by using the calcium silicate hydrate slurry, the lightweight calcium silicate molding of high quality which has satisfactory operability, and has excellent durability as well can be obtained with high efficiency.
