EFFECT OF IROKO AND SAPELLI SAWDUST MIXTURE ON THERMAL PROPERTIES OF COMPRESSED EARTH BRICKS (CEB)

This study analyzes the effect of the mixture of Iroko and Sapelli sawdust on the thermal properties of compressed earth bricks(CEB). Various compositions were carried out for proportions of 15% sawdust consisting of the mixture of two wood species (Sapelli Iroko) in various proportions. The earth+sawdust mixture was stabilized with 8% cement or slaked lime. The hot plate method were used to determine thermal properties of bricks.The presence of sawdust improves the thermal properties of earth bricks. On the other hand, these thermal properties do not systematically evolve in the same direction as the proportion of the species with the greatest density (Sapelli) in the sawdust mixture.
