This study presents a soil mixing approach to enhance particle distribution for compressed earth block (CEB) construction. Significant improvements in soil composition were achieved through detailed analysis of soil characteristics and iterative adjustments. Our method involved optimizing curves for the maximal soil diameter to suit different CEB production needs, ensuring applicability across soil types. Supplementary soil from a beach area rich in coarse grains was key in correcting the initial soil’s grain distribution. A systematic method for determining soil mixture percentages using various sieve diameters ensured consistency. The corrected soil showed an increased dry density of 2032 kg/m³ at 8.25% water content, compared to 1965 kg/m³ for the initial soil, demonstrating the practical benefits of this approach. Future research should explore alternative techniques and real-world applications to promote sustainable construction practices and eco-friendly materials.
