The CLF-40 Automated Compressive Load Frame was designed to determine the compressive strength of a well cement or proppant. The most common means of determining the compressive strength of a cement involves applying a force to the sample at a constant rate until the sample fails. The maximum loading at which the cement fails is defined as the cement's compressive strength.


  • Windows® based, Computerized Data Acquisition and Control system: provides detailed test information, precise control, and allows cylindrical and cube-shaped samples
  • Small foot-print: saves valuable lab space and increases efficiency with quick and easy clean up
  • Safety minded: clamshell head design and safety switches protect people and equipment from possible debris during operation
  • Prevents over pressure: a safety head, rupture disk, and high-pressure alarm assembly
  • Self-Aligning platens: easier to load samples and allows for equal force to be applied
  • Communication: operates in standalone or with computer control via RS-232 or Ethernet connections
  • Loading Rates: variable load rate and constant load testing

Data Acquisition Features:

  • Tailored interface so the most common actions are the easiest to locate
  • Tab and drop-down based software, optimizing page screen areas, without sacrificing the amount of information presented at once
  • Capable of testing varying samples and displaying results on a real-time chart
  • Records historical data for easy analysis
