AZA 0849 SHRINKAGE LIMIT SET

Description

Shrinkage Limit Set – AZA 0849 from Azalab is a crucial instrument in geotechnical engineering for determining the shrinkage limit of cohesive soils. This parameter is part of the Atterberg limits and is essential in understanding the volume change behavior of soils when subjected to drying.

IS 2720 (PART-VII) ASTM D 427, BS 1377, AASHTO T 92. Shrinkage limit is the maximum water content at which a reduction in water content does not cause an appreciable reduction in volume of the Soil Mass. At shrinkage limit, on further reduction in water, air enters in to the voids of soils and thus keeps the volume constant.
The apparatus can be used to determine shrinkage limit and to calculate other shrinkage ratio, shrinkage index and volumetric shrinkage.
Set consists of one each:
1. Porcelain evaporating dish
2. Shrinkage dish
3. Glass cup
4. Perspex plate with three metal prongs
5. Flexible spatula 100mm
6. Glass cylinder
7. 25ml x 1ml, supplied without mercury
6. Plastic wash bottle 500ml
Optional Accessories:
Mercury supplied in bottle of 500 gms. at an extra cost.

What is Shrinkage Limit?

The shrinkage limit is the maximum moisture content at which a reduction in water content does not result in a decrease in the volume of the soil mass. This is vital for identifying the shrink-swell potential of clayey soils, helping engineers design safer foundations and earthworks.

Application and Importance

Shrinkage limit data is used in:

• Classifying fine-grained soils

• Designing earth dams, embankments, and retaining walls

• Predicting potential soil movement

• Assessing soil behavior under changing moisture conditions

For engineers and researchers, the shrinkage limit set provides a reliable, repeatable method of gathering critical soil data. It is especially useful in civil engineering, agriculture, mining, and soil conservation projects. Azalab’s Geotechnical Instruments Category
