The concrete maturity method is a fast approach for estimating the compressive strength of concrete in the field. This method accounts for the combined effects of time and temperature on the strength development of concrete during curing. One of the major challenges for the concrete industry is getting an accurate in-situ estimation of the compressive strength of concrete at the optimal time during the project.
The maturity method provides a rather simple approach for making dependable estimates of in-place strength during construction. It allows contractors to expedite schedules and improve construction methods without solely relying on standard test specimens and laboratory testing. Because each concrete mix has its own strength-maturity correlation, it can be used to estimate mix strength at any moment following the concrete placement.
The concrete maturity tool created by Giatec makes it extremely easy for anyone to calculate the maturity of concrete and generate a maturity-strength graph. The simplified maturity calculator allows contractors, students, or anyone else with the necessary data to input temperature values and strength values in order to generate a graph. Alternatively, users can use the maturity-strength calculator to input maturity and strength values or import a CSV file to generate the graph.
The main advantage of the maturity method is that it uses the actual temperature profile of the structure’s concrete to produce an estimation of in-place strength. The traditional method relies on the use of field-cured cylinders, which do not replicate the same temperature profile or estimate in-place strength as accurately. With this method, information can be collected in real-time since calculations are done on-site at any point during the project. With the use of tools such as the Concrete Maturity Tool, processes are streamlined even further as the tool does calculations for you and eliminates the possibility of miscalculation, assuming data is properly inputted. As a result, project workflow is optimized and timing of construction activity can be established using more accurate in-place strength information.
