Abstract Manufactured sand often has granules with uneven shapes, which affects the quality of concrete. Hence, detection shape manufactured is important to ensure In this article, an image analysis system used detect particle and flow time aggregate angularity test as a reference study correlation between several characterization parameters method. The result shows that equivalent ellipse axial ratio Ae best index for evaluating uniformity shape. Repeatability tests single-grade graded materials showed maximum repeatability errors three types material are 0.5 %, 2.52 2.97 respectively, error 0.85 %. When closer sphere, measurements high. Therefore, method can meet requirements effectively monitor use in
