    The slurry produced as a by-product of construction works has a high water content and contains a large amount of fine clay particles, thus necessitating its flocculation and dehydration for the sake of volume and water content reduction. The purpose of this study is to investigate the consolidation properties of floes of different sizes, made by the application of flocculant to sludge, under lower consolidation pressures. Three types of experimental studies were carried out using clay floes of different sizes. Based on the results of dewatering and consolidation tests, it can be concluded that the floes' compressibility decreases with the increase in their size under consolidation pressures below 10 kPa, and that the hydraulic consolidation test could reliably predict initial deformation under lower consolidation pressures.
