METHOD OF SELECTING A METAKAOLIN TO BE INCORPORATED IN A COMPOSITE MATERIAL COMPRISING CEMENT AND GLASS

摘要

Method of measurement and selection of a metakaolin and product based on cement reinforced with glass fibers containing such a metakaolin comprising a chemical analysis of metakaolin, a measurement of the capacity to fix lime, of metakaolin, by Chapelle test at 90 degree (s) C, a measurement of the specific surface of the grains of metakaolin, a measurement of the capacity to fix lime, of metakaolin, by Chapelle test at 50 degree (s) C, and the calculation of the ratio between the quantity of lime absorbed per gram of metakaolin with the Chapelle test at 50 degree (s) C and the specific surface of said metakaolin.
