Concrete Thermal Expansion

A computer controlled, automated, concrete thermal expansion testing machine.

Fully automated

  • Fully automated testing machine for measuring concrete thermal expansion characteristics
  • Includes testing frame with LVDT, USB control interface, insulated water bath, calibration sample, and computer with CTE-200 software

User-focused design

  • Rugged and dependable
  • Includes one measuring frame, can be expanded for measuring two samples simultaneously
  • Challenge Technology reputation for building the highest quality testing equipment available

How it works

  • The operator places the sample into the test frame, enters the sample height and the data file name at the beginning of the test and the testing proceeds unattended
  • Preprogrammed computer controls, measures, and records all CTE data and shuts down upon test completion
  • Includes a 304 stainless steel calibration standard and calibration software for automated calculation of frame correction factor
  • Certified reference samples are available in 410 stainless steel and Titanium
  • Software follows the AASHTO T 336-11 testing protocol
