To develop a correlation curve for the particular concrete to be tested
Study Notes
Windsor Probe
- Measures the in-place strength of concrete
- Related to the type of coarse aggregate used in the concrete, as the probe's results can be affected by the size and type of aggregate
- The rebound hammer, which is used in conjunction with the Windsor probe, can affect the concrete surface by creating a rebound value that is influenced by the surface hardness and roughness of the concrete
Improving Accuracy
- To improve the accuracy of the estimated in-place strength using the Windsor probe, multiple tests should be performed at different locations and depths to account for variations in the concrete
Companion Cores and Cast Cylinders
- Companion cores or cast cylinders are used in conjunction with the Windsor probe test to provide a more accurate representation of the concrete's in-place strength by comparing the probe's results with the actual strength of the cores or cylinders
