The Challenge: Reliable Strength Development
Relying solely on lab-cured cylinder or cube breaks often results in data that does not represent the in-situ condition of the structure. Due to the volume-to-surface-area ratio, real-world elements often hydrate at higher temperatures than small samples, meaning laboratory results can be overly conservative, leading to unnecessary project bottlenecks. Conversely, in cold weather, cylinders might overestimate strength if they are not stored in identical conditions to the pour.
The Solution: Real-Time In-Situ Strength Calibration
This solution utilizes the Maturity Method (ASTM C1074) to estimate concrete strength directly in the structure. Sensors track the temperature history, calculate the Time-Temperature Factor (TTF), and compare it against calibrated reference curves for the specific mix design. Our system serves as a high-precision digital equivalent to manual calculation procedures. This provides engineers with immediate MPa readings based on real-time activation energy calculations, allowing for data-driven decisions on formwork stripping, post-tensioning, and load application.
Engineering Impact & Key Benefits
-
Accelerated Cycle Times: Scientifically determine the exact moment for formwork stripping, post-tensioning, or jumping climbing systems.
-
Code Compliance (ASTM C1074 & EN 13670): Use validated mathematical models (Nurse-Saul or Arrhenius) instead of uncertain "rule-of-thumb" estimations.
-
Enhanced Safety: Gain confidence that critical structural milestones are based on the actual strength of the pour, regardless of laboratory conditions. Avoid premature stripping and structural risks.
-
Reduced Testing Costs: Minimize the logistics and labor required for casting and breaking high volumes of field-cured samples. No need to wait for test results!
- 24/7 Monitoring and Analysis: Once installed, sensors send data around the clock. Access it via the web application for real-time insights, documentation, and detailed reports.
- Sustainability and Cost Efficiency: Optimize concrete mixes to reduce carbon emissions without inflating costs. Fine-tune performance for a smaller environmental footprint.
