Traditional methods for monitoring the strength of concrete usually require some destruction of the final product. While the test is not applicable for all situations, core extraction, or core cutting, is a fairly accurate way of determining strength. Since a minimum thickness is required for core extraction and the strength of the extracted cores can vary depending on other factors, this method for measuring requires caution.
Popular with the Indian government, wireless tests, more aptly called ultrasonic pulse velocity (UPV) tests are quickly taking off. Because this method is nondestructive and on-site, it is growing in popularity. As far as concrete technologies go, there is room for improvement with wireless measuring techniques. However, companies are working to provide real-time data with temperature and humidity sensors transmitted to smartphones or other wireless devices.
Rebound hammer tests measure the elastic, hardness and penetration properties of concrete surfaces. UPV tests in coordination with rebound hammer tests can provide strength results without damaging the concrete. In some cases, these results can be more accurate than core extraction.
At Standley Batch, we provide the equipment for mixing so you know your aggregate is controlled in precise environments. When a recipe yields the strength results you need, with our control system, you can save and reproduce the recipe as needed.
