Title: Setting-modified cement and method of manufacturing the same
Inventor: SAKAKIBARA HIROYUKI
IPC: C04B24/32
Filed: 2000-03-03
Abstract: PROBLEM TO BE SOLVED: To simplify the control of setting time of a cement by providing a setting-modified cement scarcely influenced by the ambient temperature condition, and further to provide a method of manufacturing the setting-modified cement.
