railway DFCCIL Executive 2025 Mock Test Soil Mechanics and Foundation Engineering Classification of Soils
Which of the following statements are correct with respect to grain size distribution curve?
I: The grain size distribution curve, having a horizontal line (parallel to x-axis) for some distance, shows poorly graded soil.
II: The grain size distribution curve, having a horizontal line (parallel to x-axis) for some distance, shows gap graded soil.
III: If the value of Cu (coefficient of uniformity) is large, it shows the presence of wide range of size of particles.
IV: If the value of Cu (coefficient of uniformity) is large, it shows the presence of narrow range of size of particles.
