Grain Size Distribution – Geotechinal Portfolio

The grain size distribution lab demonstrated the different particle size that were found through the soil sample. A sieve analysis (ASTM D422) of 500 grams of soil was put through a sieve analysis, and then classified from coarsest ( the sieve on the top) to fine (the sieve on the bottom).

Lecture 2 grain size distribution - SlideShare

Oct 28, 2016  A sieve analysis is used to determine the grain size distribution of coarse-grained soils. For fine-grained soils, a hydrometer analysis is used to find the particle size distribution. Particle size distribution is represented on a semilogarithmic plot of % finer versus particle size Summary Dr. Abdulmannan Orabi IUST 85 86.

Particle Size Distribution - digitalfire

Particle size distribution (PSD) measurements are an excellent way to characterize a material for quality control purposes. When problems occur in a ceramic process, particle size distribution information about the materials and body can help explain the causes. PSD information is also critical to spot wear in grinding equipment.

Standardisation of particle size distribution (PSD) is a prerequisite to achieve compatibility of soil data among various countries with different texture classification systems. Therefore, several mathematical models have been proposed to accurately represent PSD. Previous studies evaluated the performance of such models to describe PSD of soils from temperate regions.
