Make the Most of the Concrete Maturity Method with These Calibration Tips

One of our favorite subjects to write about is concrete maturity. One of—if not the—most important part of using concrete maturity onsite, is the calibration process.

While concrete maturity is not a new concept in the industry, it is still one that is not fully adopted. More and more engineers are seeing the benefits of using the maturity method in their projects and are accepting that it can be the most reliable way of testing concrete strength if done properly. The method presents many advantages, including the ability to predict when your concrete will reach the required strength, allowing you to optimize your timelines. Here are 10 tips to help you with your concrete maturity calibration and get your project off on the right foot:

Before You Start Your Concrete Maturity Calibration, Review the ASTM C1074 Standard in Detail

This doesn’t only apply to ASTM C1074, Standard Practice for Estimating Concrete Strength by the Maturity Method, it applies to any standard applicable to your project. Always ensure you are on top of the guidelines and know all the information relevant to the application of your concrete. It’s important to know which standard applies to your country or state, as it could differ. Our blog post on calibrating your concrete maturity sensors outlines everything you need to know.

Make Sure Your Mix is Consistent Throughout Your Concrete Maturity Calibration

This is the first step to avoiding discrepancies. Consistency is key in any concrete project. If you start changing your mixes throughout your project you’ll have to go back to the lab and perform new calibrations for each new mix added. This includes both getting a new mix from your concrete supplier and changes to your current mix like adding more water or ice from the time your mix is created to the time it is placed on site. If anything changes in your current mix, aside from the allowed admixtures, a new calibration is required.
