What is a sieve?

Sieve analysis is a procedure for quantification of the size and types of particles present in a certain sample of soil and their relative frequency of occurrence. The analysis can be performed on inorganic materials such as gravel or aggregated mixtures. The sample passes through the Sieves series, starting with a sieve with large openings, over the gradually smaller sieves. The results of the sieve analysis can inform geologists and engineers a lot about the composition of the sample and how a particular soil or other mixture will behave in building engineering and building environments.

is a simple device consisting of a frame designed to hold material and DNA made of wire mesh. The gaps in the network determine the size of the particles that can pass it. Forces are classified according to any of the standards. Most standards use the number to classify individual needs that correspond to the number of holes in 1 linear thumb (2.54 cm) network.

different standards may vary slightly and because the diameter of the wires can affect the sizeholes, there are a very large number of possible combinations and sizes. This means that two forces classified as size 10 can go through particles of different maximum sizes. This should be taken into account by the tester and sieve size, as well as the standard used, it is necessary to record in the resulting message.

Sieve analysis results are listed as a list of the percentage of the test sample according to the weight that passes through each sieve. For example, the first, largest sieve can go through 95% of the total weight sample, the second may pass 85%, etc. By analyzing this data, the relative composition of a particular sample can be quickly seen with regard to the distribution and frequency of particle size.

For trained and experienced engineers and Geologs, this data represents valuable information about how a particular soil or other mixture can behave under different conditions, including compaction, settling and shifting. The risk of landslide and the behavior of the flood VOD, especially with regard to how the soils can absorb them, can be assessed using the sieve data by the analysis along with other information. The decision on building and construction projects often relies strongly on this kind of data. Further use of data on sieve analysis may include agriculture, environmental impact studies, river basin management and soil decision.
