Pinhole Dispersion Apparatus
- Product Code: SL244
Standard : ASTM D4647, BS 1377:5
Some soils that tend to spontaneously disperse in water are considered "suspect floors" in terms of erosion and piping. These floors are known as "dispersive clay or dispersive floor" in ground mechanics. These structurally unstable soils can be easily dispersed and subjected to high-grade erosion. If the use of disperse clay grounds in the construction of water bodies, fill dams and road fillings is in question, they should be well-defined and constructed with appropriate techniques. Otherwise, we are faced with serious engineering problems that go as far as the end result. Erosion due to the chloride dispersibility feature; kiln mineralogy depends on the nature and amount of the dissolved salt content in the soil and the chemical structure of the soil and in the erosion-causing water.
This test technique allows simple classification of soil samples and determination of soil sample quality.
The pinhole tester is used to determine the tendency of the floor to wear with water flow.
