SOIL CAKING AGENT

SOIL CAKING AGENT

PROBLEM TO BE SOLVED: To obtain a soil cake capable of maintaining a pH close to neutrality over a long period of time at a high caking rate. SOLUTION: The initial strength of a soil cake is enhanced by adding 20-80 pts.wt. hemihydrate gypsum, the final strength of the soil cake is enhanced by addin...

Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a soil cake capable of maintaining a pH close to neutrality over a long period of time at a high caking rate. SOLUTION: The initial strength of a soil cake is enhanced by adding 20-80 pts.wt. hemihydrate gypsum, the final strength of the soil cake is enhanced by adding 80-20 pts.wt. blast furnace slag and a pH of the soil cake near neutrality is maintained over long period of time by further adding 0.05-5.0 pts.wt. sulfuric acid compd.
