Title: Portland cement for producing alc and production of alc
Inventor: AONO YOSHIMICHI
IPC: C04B111/40
Filed: 2000-02-14
Abstract: PROBLEM TO BE SOLVED: To keep low viscosity for the time until the foaming is completed after pouring ALC slurry to the frame mold without increasing the kneading water by using a specific amount of hemihydrate gypsum as the gypsum in the cement.
