Abstract In this chapter, a state of the art of Particle Size Distribution (PSD) measurement of bio-based aggregates and characterization methods is presented. Shiv particles coming from the stem of plants cultivated either for their fibers (hemp, flax, etc.) or for their seeds (oleaginous flax, sunflower, etc.) are very different from the mineral aggregates typically used in concretes. Owing to the structure of the stem of the plant they are made from, such aggregates are generally malleable, elongated and highly porous with a low apparent density. Irregular shape are generally observed, especially in case of shiv coming from fiber plant due to the shredding action of the decortication process. Such ground bio-mass lead usually to uni-modal size distribution that can be efficiently characterized using basic distribution models with two parameters. Starting from the standardized tools and techniques developed for mineral aggregates, other technics using image processing are investigated and discussed in the global perspectives of the effect of the PSD on the properties of the in-service building material.
