Overview

Reveals the mineralogical properties of clays in northern Cameroon for potential use in cement, indicating their suitability for industry.

Key Points

  • The study aims to characterize the physico-chemical and mineralogical properties of Boula-Ibi and Indjode-Bidzar clays for their potential use in cement production.
  • Detailed particle size distribution analysis was conducted.
  • X-ray diffraction and X-ray fluorescence spectrometry were used to analyze mineralogical composition.
  • Mechanical tests assessed the performance of calcined clays as cement replacements.
  • The compressive strength of cement with calcined clay decreased significantly, with values dropping from 26.4 MPa to a maximum of 18.03 MPa based on different mixes.
  • Mineralogical analysis revealed a composition mainly of kaolinite, smectite, and quartz, confirming their suitability for cement.
  • Specific surface areas ranged from 11.16 to 62.99 m2/g, indicating varied clay properties that support cement production.
