Sieve analysis is a method used to determine the particle size distribution of a granular material. This process involves passing the material through a series of sieves with different mesh sizes, allowing larger particles to be trapped while smaller ones pass through. The weight of the material retained on each sieve is measured to create a profile of the particle sizes present in the sample. This technique is commonly used in fields such as geology, construction, and material science to assess the quality and suitability of materials like sand, gravel, and soil. The results help engineers and scientists make informed decisions regarding material selection and usage.
