Soil Shrinkage Test Apparatus Consists of The Main Part and The Quasi-soil Part
Equipment description:
Apparatus is used to test moisture content of contracting limit after the specimen lost moisture, linear contracting rate, body contracting and contracting coefficient.
The instrument consists of the main part and the quasi-soil part.
1, The main part of the floor, table pole folder table, plate and other components.
2, Head composed of quasi-soil part of the guide ring, ring knives, ring orientation, prospective soil
Function Principle
Smear Vaseline in the ring knife. Soil samples introduced from the ring knife, and immediately weighed, set the sample in a perforated plate into the instrument, well weighed, a note of the early readings in the 20 read ° C for shrinkage test (can be equipped with ten thousandth of one kilogram scales). And then, based on soil test procedures (SDS.01-79) operating to the scale reading is essentially the same date, then soil samples in 100 - 105 ° C temperature drying to constant weight, saying the soil is heavy. Scale from the two vertical four positions in the horizontal and vertical measurement first, then computing.
After using Soil shrinkage Instrument
The instrument should be to wipe clean, coated with a thin layer of grease to prevent rust
