Sand equivalent test kit

The Sand equivalent test kit is used to determine the relative proportion of clay-like fines in granular soils and fine aggregates. It is used in conjunction with the Durability Index Test, which measures the resistance of aggregates to produce clay-like fines when subjected to degradation.

The Sand Equivalent Test Kit typically includes the following components:

• Four clear plastic graduated cylinders
• A siphon assembly
• An irrigator tube
• A weighted foot assembly
• A plastic funnel
• A solid stopper
• 8oz stock solution
• Measuring tin

The test is conducted by(Any link) adding a sample of soil or aggregate to a graduated cylinder with a calcium chloride solution. The mixture is then shaken for a specific period of time. After shaking, the clay-like fines will suspend in the solution, while the sand will settle to the bottom. The height of the sand layer is then measured.

The sand equivalent is a unitless number that ranges from 0 to 100. A higher sand equivalent indicates that the soil or aggregate contains fewer clay-like fines and is therefore more desirable for use in construction applications.

Here are some of the benefits of using:

• It is a relatively simple and inexpensive test to perform.
• It can be used to quickly and easily assess the quality of soil or aggregate.
• The results of the test can be used to select appropriate materials for construction projects.
