Concrete Creep Tester (Pro) – QualiCCTR™ Pro

A Concrete Creep Tester measures how concrete slowly deforms under a sustained compressive load. QualiCCTR™ Pro is an automatic creep frame system designed for concrete cylinders and cuboid specimens loaded over time, so labs can quantify creep deformation under controlled conditions. The system uses a touchscreen control interface and real-time monitoring to support long-duration testing with stable pressure loading. It is intended for single-direction compression creep testing at constant temperature in a humid-free environment.

QualiCCTR™ Pro combines a rigid creep loading frame with an automated control cabinet for sustained-load testing. It displays and records key parameters such as load/pressure, compression deformation, and environmental readings during the test. Data is stored continuously, helping preserve results during long runs. The frame design supports stable specimen placement and repeatable alignment for compression creep measurement workflows.

Concrete Creep Tester (Pro) – QualiCCTR™ Pro Applications

  • Long-term creep characterization for structural design inputs: Supports creep strain tracking under constant compressive stress, which helps engineering teams compare long-term deformation trends between mixes and curing conditions.
  • Mix design, admixture, and materials research: Helps research groups evaluate how cement type, SCMs, admixtures, and aggregates affect sustained-load deformation over time. Results are often used for comparative studies and internal benchmarks.
  • Quality control for projects sensitive to long-term deformation: Useful when creep performance needs verification for critical concrete applications. The system supports consistent loading and repeatable monitoring for lab QA programs.
  • University and training laboratories: Works well for teaching time-dependent concrete behavior because the interface shows load and deformation values clearly while tests run. It also supports structured data capture for lab reports.

  • ISO 1920-9:2009 – Testing of concrete: Determination of creep of concrete cylinders in compression.

Concrete Creep Tester (Pro) – QualiCCTR™ Pro Key Features

  • Touchscreen monitoring and recording: Displays and logs pressure/load, compression deformation, and environmental readings in real time for long tests.
  • Data retention during long runs: Test data is stored continuously to reduce the risk of losing results during unexpected power interruptions.
  • Safety-cover option for the creep frame: Helps reduce accidental specimen damage and supports safer operation during extended tests.
  • Disc-spring loading structure for stable sustained load: Uses a disc-spring assembly and balanced supports to help maintain steady loading and reduce eccentric effects.
  • Hydraulic pump station with pressurized oil cylinder: Supports convenient pressurization and load adjustment during setup and testing.
  • High-rigidity bearing plate and stable frame base: Designed for steady positioning and repeatable creep deformation measurement under compression.
  • Transportable assembled structure: Shipped as a complete unit so onsite installation can be faster after positioning and hoisting.
  • Complete accessory set for immediate testing: Configuration is intended to support quick commissioning for standard creep test routines.

Theory and Method

Concrete creep is the time-dependent compressive strain that develops while a specimen remains under sustained load. In a creep test, a prepared specimen is loaded to a target compressive stress and held at that level for an extended period. Deformation is measured at defined intervals, then reported as creep strain versus time under specified environmental conditions. QualiCCTR™ Pro supports this workflow using stable frame loading and recorded deformation signals during long-duration tests.
