Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.ABSTRACT The use of laterite soil with high Al and Fe content has been investigated as a novel supplementary cementitious material (SCM) to replace traditional mineral materials for clinker substitution. High‐energy ball milling was used to mechanochemically activate laterite and change its reactivity.

, 1972 Data arc presented showing the changes in physical properties which occur during the calcination of Bayer-process gibbsite at temperatures up to 1400°C. The various stages of the calcination were examined using differential thermal analysis, X-ray diffraction, low-temperature nitrogen adsorption, optical and electron microscopy, and particle-size ...

Fluoride removal by adsorption on thermally treated lateritic soils
Bulletin of the Chemical Society of Ethiopia, 2012 The ability of lateritic soils to remove fluoride from water has been studied. Important issues considered in the study include the relation between the mineral composition of soils and their ability to remove fluoride, the effect of thermal treatment of
