The moisture meter you own or buy will define how you measure your aggregate moisture levels. While most sensors measure bulk moisture, some measure only surface moisture. In either case, though, they can be calibrated to read surface or free moisture. This is the moisture that reacts with the cement in the mix and, therefore, the only moisture

Moisture sensors can measure moisture levels in materials being discharged from bins, on conveyor belts or within vibratory feeders. The sensors are placed directly in the flow of the material, and take 25 measurements per second as the sand or aggregate flows over the ceramic measurement surface. These measurements are then transmitted to the plant control system in real time. This allows the

· Dumping sand or gravel from the bed of a truck or a scraper places the granular material in a relatively loose condition, particularly if the sand contains only a small amount of surface moisture. This material must be compacted to provide the required strength. If the material is not compacted, then it can lead to settlements in the future.

· If the moisture content is higher than the aggregate''s absorption value, the aggregates will contribute free water to the mix. If the moisture content is below the absorption value, the aggregates will absorb a portion of the mix water. For mix designs based on raw materials in an ovendry condition, make the following adjustments.

· Spread out the sand onto sheet trays or baking pans no more than 1/4inch thick. Bake the sand for one hour. Keep the oven door slightly ajar and run the exhaust over the stove to remove any baking odors from the kitchen. Flip the sand over if it is still wet on the bottom. Let the underside bake about a half hour or as long as needed to dry it.

Moisture is an important component in all green sand casting. Water is generally added at 25% of the weight of the mixture. The hydrostatic bonds between water molecules strengthen the sand: it is these bonds that build sandcastles from wet sand on the beach, and the same forces are at work in the foundry. It is the water that increases the green sand''s capacity to handle shear stress and
