SDI Clegg Impact Soil Tester Type CIST/882

Identify poorly compacted grounds and ineffective rolling of materials with the Clegg Impact Soil Tester type CIST/882. Also known as the Clegg Impact hammer, it facilitates the measurement of shear strength (soil) and consolidation levels during trench re-instatement. Completed through assessing effective stiffness and density of material particles, producing rate of strain into one reading of impact value.

The Clegg Impact Soil Tester also known as the Clegg Hammer or Clegg Impact Hammer, consists of a 4.5kg compaction hammer operating within a vertical guide tube. The unit measures the stiffness of a material within a selected region of impact, determined by the deceleration rate of the hammer. The hammer falls from a fixed height through the tube, striking the selected test surface area underneath. A precision accelerometer mounted on the hammer generates an electrical charge which is fed by a cable to a hand held digital readout unit. The fast microcontroller in the readout scans and filters the signal and registers the deceleration in units of Impact Value (IV) up to 100 IV. The IV is an indication of soil strength and shows good correlation with results from CBR tests.

ESS Code: HIST.1
