Maturity vs Pull-Out Method for Concrete Testing: Which

2020-5-8  The maturity method is a technique that measures concrete strength in real-time and is based on the principle that concrete strength is directly related to its hydration temperature history. It is most often used for testing concrete at early ages, usually less than 14 days. The temperature data is collected with sensors that are installed within the concrete formwork and subsequently uploaded ...
