HYDRAULIC COMPOSITION AND CONCRETE FLOOR STRUCTURE USING THE SAME |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To obtain a hardened body having excellent handling property, excellent rapid hardening performance, horizontal leveling performance and having a good finished surface because high flowability is stably maintained for a long time even when the temperature condition is changed in the working. <P>SOLUTION: The hydraulic composition contains a hydraulic component containing a cement component and gypsum and fine aggregate and the concentration of residual calcium hydroxide in the gypsum is≤0.5 mass% per 100 mass% gypsum containing the residual calcium hydroxide. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
