SLIDE SHOW: Concrete is monitored and tested for strength in order to progress work, allow traffic on the pavement or to determine final acceptance.
The compressive strength of concrete has a relationship to time and temperature specific to the mix design. As concrete hydrates, it cures and gains strength. Hydration occurs as the cement becomes fully saturated by the water in the concrete. The hydration process produces heat. Taking time and temperature readings of the concrete as it cures and gains strength allows workers to track the curing process.
