Effect of reinforced recycled sawdust-fibers additive on the performance of ecological compressed earth bricks

This study assesses the potential of waste wood sawdust, as a construction material additive, on the mechanical, thermal and physicochemical properties of compressed earth bricks. Following X-Ray Diffraction and Fluorescence analysis, the used raw clay material, retrieved from Ifrane, Morocco, was found to be of type Illite, with a prominent SiO2 content, 59.60%, making it a suitable construction material. Multiple waste additive proportions were analyzed (0%, 1%, 3%, 7%, 15% and 20%), by weight, at different sizes: small size: (δ ≤ 0.5 mm), medium size: (0.5 mm
