What is Metakaolin? Updated: Oct 27, 2022. Metakaolin is an offwhite manufactured pozzolanic mineral admixture that considerably increases many functioning features of cementbased products. This product is a refined kaolin clay that is calcined under a precise temperature range between 600800 Celsius over a 12hour time period.

Metakaolin was produced by thermal treatment using three different calcination temperatures ranged from 600 to 700°C and calcined for 4 hours. Prior to calcination, some specimens will be mechanically milled using planetary ball mill for 15 minutes with the milling speed of rad/s and will also be calcined with the same parameter.

The source of calcium sulfate (CS) for this study was gypsum, in its anhydrous form (Anhydrite). Initially, the gypsum was submitted to ballmilling for 1 h, then sieved through a µm mesh sieve, and subsequently calcined in a muffle at a temperature of 650 °C for 1 h under a heating rate of 50 °Cmin −1 to reach anhydrous form [3, 4, 9].
