7 Truths about Concrete Moisture - Concrete Moisture

The significant movement of water within the slab means that the moisture content will vary by depth. Generally, the surface of the slab is drier, while deeper in the concrete, the moisture content is higher. One more important note: Moisture doesn't just flow out of a slab. The flow of moisture …

- Aggregate Moisture and Making Adjustments to Concrete

moisture content of an aggregate sample is the sum of the absorbed moisture and the free surface moisture. The moisture content of the aggregate is defined at four states. When the aggregate has no moisture on the surface or the interior pores then the aggregate is in a dry (sometimes called oven-dry) state. When some of

Moisture Content - Cornell Composting

Note that the moisture goal must be between the moisture contents of the two materials being mixed. For example, suppose you wish to compost 10 kg grass clippings (moisture content = 77%). In order to achieve your moisture goal of 60% for the compost mix, you calculate the mass of leaves needed (moisture content = 35%):
