16. Large Restrained Shrinkage Test

  • Estimates cracking tendency of concrete in large structures such as slab or shotcrete lining
  • The hydraulic jack in the test rig enables drying from top and bottom surface
  • The restraint is provided by an instrumented steel ring with 1,200 mm in outer diameter, 55 mm in thickness and 200 mm in height
  • The concrete ring specimen is 1,200 mm in inner diameter, and 200 mm in height and thickness of concrete ring can be set from 100 mm to 290 mm
  • Application focused, providing different degrees of restraint
