Accurately monitoring the curing of concrete can be critical on large construction projects. If a slab is not given sufficient time to cure, cracks can develop when the next slab is poured, which would ruin that section. Companies have typically used temperature loggers with wires from the device running into the concrete, since concrete gives off heat as it cures. But wired sensors can be too cumbersome for large projects, so in such scenarios, a concrete consultant often sets a conservative estimated curing timeline based on the material being used, as well as other conditions. This often means extra time is built into a project’s timeline, in order to ensure that all concrete poured is fully cured before employees proceed to the next step.
