A widely used milling machine can be used, such as an atomizer, pin mill, jet mill or ball mill. Of these, the atomizer is preferred. Regarding the specific milling conditions when using an atomizer, a rotational speed of 5000-15000 rpm could be used for the main axis, for example, with a feed rotation of 10-30 rpm and a screen hole size of 1-5 mm.
The IOTs and CGS were ground using a ball mill (SM-500, Wuxi Proposed Instrument Machinery Co., Ltd., Wuxi, China) for 20 min and passed through a 0.075-mm sieve. Five experimental the geopolymer groups (A1, A2, A3, A4, and A5) were prepared using powder mixtures containing varying proportions of IOT and CGS powder .
