AB  - The aim of this work is to study the effect of the incorporation of wood ash from the combustion ofbiomass waste on the thermal properties of compressed earth bricks (BWA). These bricks were obtained as apartial substitution of the soil with different contents (0, 5, 10, 15 and 20% wt). The specimens manufacturedwere compacted with a compaction stress at 10 MPa, conserved in the laboratory at a temperature of 20 ± 2 °C,then allowed to harden for 7 and 28 days. The results showed that the partial substitution of the soil leads to adecrease in thermal properties.Thermal conductivity values were decreased to different soil substitutionproportions and with curing time. Minimum values were achieved for specimens containing 20% by weight ofWA, with better thermal insulation, at thermal conductivity values ranging from 0.78 W/mK in BWA at 28 daysand 1 W/mK in BWA at 7 days. This decrease was attributed firstly to the quantity of water consumed during thepozzolanic reaction that occurs between the soil components and the lime of the WA, secondly to themicrostructure of this soil used.
