It suits the needs of quality control and production in food, pharma, chemical and other industries. Benefit from: Accurate results through precise weighing and temperature control; Intuitive operation with step-by-step user …
What this involves is a piece of equipment that is baseplate, a drill rod, and you would accompany that with a heavy handheld mallet or a sledge hammer. This gauge is going to give you a moisture content reading and it''s going to give you a density reading.
Compaction purposes and processes Compaction as a construction process Compaction is employed in the construction of road bases, runways, earth dams, embankments and reinforced earth walls. In some cases, compaction may be used to prepare a level
· Moisture meters are especially necessary for woodworking because wood is extremely susceptible to moisture fluctuation. Fresh-cut logs may have up to 80 percent moisture content, while kiln-dried lumber may be as low as 6 percent. Construction lumber grade-stamped "S-dry" is required to have a moisture content of less than 19 percent.
· Aggregate moisture content tests require the following equipment: A balance or scale that must be accurate to within 0.1% of the test load at any point within the balance''s range of use. A source of heat such as electric hot plate, gas burner, ventilated microwave oven or ventilated oven.
NOTE The moisture content is expressed as a percentage by mass. 3 Principle A known mass of butter is dried in the presence of pumice stone at 102 C ± 2 C. The remaining dry mass is weighed to determine the loss in mass. 4 Apparatus Usual laboratory ...
· The total moisture measured in the test represents both the free moisture and the moisture that the aggregate absorbs. Only the free moisture becomes part of the mix water. The absorbed water, usually about 1 percent, remains within the aggregate. If the coarse aggregate is unusually porous, the absorption should be determined by a separate test.
If you''re buying a newer stucco home or you already own one, there are a few ways to determine (or attempt to determine) if there is a moisture problem. Exterior probe testing. This involves drilling 3/16" holes in stucco at strategic locations and then inserting a moisture probe into the wall to measure the moisture content.
Deterioration of stone proceeds usually at higher relative humidity, above 65%, and is frequently asso-ciated with freeze–thaw weathering. The deterioration of external walls made of porous building materials is caused by the excessive moisture content 2.2
All materials have a specific moisture content, which is bound in the material, but at its least materials contain nuclear residual moisture. PCE Instruments has focussed on the measurement of bound moisture which is added or expelled during the manufacture of a product, for example in hygroscopic materials in relation to the moisture of the given environment.
