Overview

Assesses clay deposits for ceramic brick production, revealing favorable properties for utilization.

Key Points

  • The aim is to characterize clay deposits in the Benue Valley for potential use in ceramic bricks.
  • Conducted physical, chemical, and mineralogical characterization of clay samples.
  • Performed Atterberg limits and particle size distribution tests.
  • Used XRD and XRF analyses for mineralogical and chemical composition.
  • Evaluated ceramic properties after firing at 900, 1000, and 1100 °C.
  • Clay samples contained 14.0% to 32.5% clay fraction and 47% to 66% sand fraction.
  • Dominant minerals were quartz, kaolinite, smectite, and K-feldspar.
  • SiO2 content exceeded 50%, while Al2O3 and Fe2O3 were above 16% and 6% respectively.
  • Increased firing temperature improved compressive strength (2.23 to 11.92 MPa) and decreased water absorption (17.99% to 4.96%).
