What is a maturity function? A maturity function is a mathematical equation used to calculate maturity. This number describes the effect that temperature and time have on the strength development of concrete. The standard definition is as: “A maturity function…
There are limitations when it comes to a full replacement of break tests. Break test results are often a requirement to comply with concrete standards. For example, you may need to perform a 28-day strength test in order to validate…

User-friendly cutting-edge software and hardware products customized to your requirements so you can keep production and construction projects on track. Our real-time, remotely available application provides 24/7 access to your production facility and onsite projects, via continuous data from our…
The maturity method has proven to be a reliable and easy to use method to estimate the development of early concrete strength. Every test method has its limitations, so in this article, we will explain five of the limitations of…
When cement, water, aggregate, and additives are mixed together, a significant heat increase occurs. This is due to exothermic processes in the reaction between the ingredients, cement and water (called hydration). Measuring the concrete temperature over time enables you to…
A sensor is embedded into concrete. The sensors functions as a data transmitter and as a metal-piece further strengthening the product. The sensor is connected to the instrument (node) which transmits via radio to our private and dedicated application. Our…
Activation Energy Represents the energy that a molecule in the initial state of the process must acquire before it can take part in a reaction. Calibration Curve Same as the “Maturity Curve” Compressive strength The strength recorded from compression tests…
During a construction project, it is very important to know the strength of concrete because it will determine when it is possible to walk on the surface, remove the form-work, or continue building the product. The problem is that concrete…
