METHOD OF PORCELAIN SELECTION E.G.METAKAOLIN INTENDED FOR ADDITION INTO COMPOSITION THAT CONTAINS CEMENT AND GLASS FIBRES |
摘要 |
The invention relates to a method for the selection of a pozzolana such as a metakaolin, intended to be coupled with glass fibre-reinforced cement. According to the invention a pozzolana is selected which has a lime-fixing capacity in the Chapelle test at 90 DEG C which is higher than 700 mg of CaO per gram of pozzolana, a lime-fixing capacity in the Chapelle test at 50 DEG C higher than 200 mg of CaO per gram of pozzolana and a relationship between the quantity of CaO fixed in the Chapelle test at 50 DEG C and the specific surface of the pozzolana which is higher than of the order of 10 mg of CaO per m<2> of pozzolana.
<??>The composite material obtained is employed in building to produce, for example, facade components which must satisfactorily resist aging. |
