Concrete / Aggregate

When working with concrete and aggregate, one of the primary considerations is moisture content of the material. Prior to mixing, aggregate can absorb high levels of moisture which affects slump if not properly compensate for which can result in spalling, cracking and any number of other issues.

The need to know the moisture content in concrete also exists after it has been poured. If moisture levels are too high it can bleed into other building materials that sit atop the concrete such as wood flooring, coatings, or structural supports, compromising their integrity.
