CEMENT COMPOSITION |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a cement composition which is excellent in fluidity just after kneading and is less in the temporal change of fluidity without raising pulverization temperature of cement clinker even when the use amount of industrical waste and/or industrial by-products as a raw material is extremely increased. <P>SOLUTION: The cement composition is characterized in that the axial length of lattice constant in a ferrite phase is≤14.565Å, and the ratio of hemihydrate gypsum in gypsum is≤60 mass%. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
