Due to the ever increasing cost of laboratory equipment to determine soil parameters such as cohesion and maximum dry density and the enormous time and energy dissipated in such experiment, this research work was attempted in order to investigate the possi ble correlation between cohesion and maximum dry density. Thirty remoulded clay samples obtained from Nsukka were used for this investigation. The clay samples were categorized into clay of low plasticity (CL), medium plasticity (CI) and high plasticity (C H) after preliminary tests have been carried out on them. To determine the correlation between cohesion and maximum dry density, unconsolidated undrained triaxial test and compaction tests were conducted on all samples and their cohesion and maximum dry de nsity values determined appropriately. Using regression analysis, correlations were developed for the various categories of clay soils. The correlation coefficient, R, obtained for the CL, CI and CH soils were 57.8%, 67.9% and 93% respectively. Based on th is correlation coefficient, it is safe to suggest that for preliminary estimates of soils, the correlations obtained for these soils will suffice.
