ProTest monitors in-situ temperature and strength of hardening concrete — giving contractors the data to strike formwork earlier, reduce propping costs, and document everything automatically as you build.

Input mix design and materials data. ProTest calibrates the maturity model to your concrete.
Embed temperature sensors in the concrete at critical locations before the pour.
ProTest continuously records temperature data and calculates maturity in real time.
ProTest converts maturity to in-situ strength and benchmarks against project targets.
Clear reports and alerts support decisions on formwork, load, and programme.
Sensors cast into the pour record the concrete's actual thermal history as it cures — twice an hour, continuously.
The Arrhenius equation converts that temperature-time history into an equivalent age — the concrete's maturity.
Maturity maps to in-situ compressive strength using a calibrated curve for your specific mix — a real MPa value, on demand.
The temperature graph tells the story directly: the slab reaches ~35°C at peak hydration while the cube sitting alongside cools to ambient (~5°C). Higher temperature means faster maturity gain — so the slab is far stronger at 24 hours than the cube suggests. ProTest measures the real thermal history inside the structure, not the air beside it.
Roughly one tonne of CO₂ is released for every tonne of Portland cement produced. Because design uses a blanket safety factor to cover the uncertainty between cube tests and the real structure, concrete is often over-specified. Measuring true in-situ strength removes that uncertainty — opening the door to a lower strength class, less cement, and a smaller carbon footprint, without compromising structural integrity.
