Effect of Water Immersion on Raw and Expanded Ugandan Vermiculite [PDF]
Minerals, 2021 Effect of water immersion at different times (from 1/2 h to 24 h) on raw and expanded vermiculite from Uganda was investigated. The expansion was carried out by electrical heating at different temperatures and by irradiation with microwaves. After, the expansibility (k) and the water absorption content (WA) were obtained and the samples were ...
