30/12/2020 · In the author's lab, metakaolin was milled for 2 h (wet ball milling, a 75 mL/100 mL ethanol solution as the solvent, rotation speed of 400 rpm, and balltopowder ratio of 5 : 1). Then, the metakaolin solution was heated at 750 ± 10°C for 2 h for dehydroxylation. Dehydroxylation caused alumina and silica to become disordered. Metakaolin absorbs water and reacts with some water to .
Metakaolin, pozzolanic additive, may be obtained by calcination of kaolin clay. The optimal conditions of the thermal treatment are: calcination temperature of 650 °C and heating time of 90 min. Calcination results in dehydroxylation degree of The produced metakaolin has pozzolanic activity g Ca(OH) 2 / g of metakaolin.

Geopolymer was produced through alkali activated of metakaolin by adjusting the oxide molar ratios of the starting materials to the fixed value of SiO 2 /Al 2 O 3 =, Na 2 O/SiO 2 = and H 2 O/Na 2 O = 10, and curing temperature at 70°C for 2 hours. The particle size of MgO was reduced by means of ball milling at 300 rpm for 5 hours and then painted on the surface of geopolymer before ...
the present invention relates to a method of making a highly reactive pozzolan, involving the steps of forming a slurry comprising metakaolin and a liquid; wet milling the slurry; and separating the metakaolin from the liquid to provide the highly reactive pozzolan. The highly reactive pozzolan produced, can be combined with at least one cementitious material to make a cementbased .
