LOW SELF-SHRINKABLE HIGH INTERSTITIAL PHASE TYPE CEMENT COMPOSITION |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a low self-shrinkable high interstitial phase type cement composition in which the self-shrinkage is low even when used in a low water cement ratio conventionally causing the self-shrinkage regardless of high amount of the interstitial phase, and a large quantity of industrial by-product/industrial waste rich in Al<SB>2</SB>O<SB>3</SB>component can be used as a cement raw material. <P>SOLUTION: The low self-shrinkable high interstitial phase type cement composition is a cement composition containing cement clinker and gypsum in which the total quantity of C<SB>3</SB>A and C<SB>4</SB>AF is adjusted to 20-30 mass% and the quantity of CaO is adjusted to 0.28-1 mass%. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
