Impact of diatoms on fabric and chemical stability of diatom-kaolin mixtures

► Diatoms decrease the tendency of kaolin to coagulate in the presence of salt. ► Diatoms significantly increases the liquid limit and plasticity of the mineral mixture. ► Diatoms increase the water holding capacity of the mineral mixtures. ► Diatoms reduce the solubility of kaolin mixtures, even in electrolyte solution.
