Analysis characterizes clays for tile manufacturing in Cameroon, suggesting suitability and optimization options.

This study aims to evaluate the properties of alluvial and lateritic clays for ceramic applications.
Sampled eight alluvial clays and one lateritic clay from Kadey, Cameroon.
Dried, crushed, and sieved materials prior to analysis.
Determined true density, bulk density, porosity, particle size distribution, Atterberg limits, and methylene blue value.
Significant variability in particle size distribution observed.
Sand content ranged from 29.31 to 85.9 wt.%, with silt from 7.7 to 47.88 wt.% and clay from 6 to 58.05 wt.%
Plasticity Index values varied between 6.7% and 33.38%, indicating differences in workability.
Methylene blue values ranged from 0.53 to 2.23 g/100g, reflecting variations in water absorption capacity.
True density of the clays ranged from 2.47 to 2.67 g/cm³, bulk density from 1.53 to 1.68 g/cm³, and total porosity from 34.08 to 42.56%.
