Resumo: Abstract The granulometric analysis is a basic tool in the characterization process of particulate materials and can be determined through numerous methods, most notably the densimeter and laser diffraction methods. However, these techniques are based on distinct physical principles that can generate different results causing doubts. The objective of this paper was to study both methods, using a standardized sample preparation according to Brazilian standard NBR 7181. Kaolin and quartz samples were used to represent the clayey and sandy soil fractions, respectively, with compositions varying from 100% to 0% kaolin content. Granulometric distribution curves and respective fractions of each composition were determined. These results were statistically compared by analysis of variance (F-test) and correlated using linear regression. The statistical comparison indicated a strong dependence between the densitometer and laser diffraction methods with and without the same sample preparation, indicating a direct correlation with 95% confidence.
