One-dimensional compression characteristics of uniformly
2.2 Test method. To explore the influence of the initial void ratio e 0 and initial particle size d 0 on the compression characteristics of uniformly graded sand, the sample mass should be calculated by defining the initial void ratio before sample preparation. In this paper, for gypsum and calcareous sand, 12 groups of compression Gypsum is a mineral that is commonly used in various construction activities, such as building walls, roofs, and floors.
