Investigation of particle characteristics and enhancing ...
· This study aimed to assess the influence of grinding on improving the pozzolanic activity of a low porosity diatomite. To that end, three diatomites were produced, with 50% passing particle sizes (D 50) between 7 and 40 μm, and characterized based on oxide composition, loss on ignition, Xray diffraction (XRD), particle size distribution, and gas adsorption (specific surface area and porosity).
