Trona, or sodium sesquicarbonate, is a fine mineral powder that has proven to be effective at removing acid gases from air emissions. While trona can be a useful component of air pollution control systems, it can be difficult to handle, particularly when moisture is present. A proposed new ASTM standard will present a repeatable, precise and accurate test method for analyzing moisture levels in…, ASTM Committee E01 Next Meeting:, Nov. 14-17, November Committee Week, San Antonio, Texas, Technical Contact: J, ames D.

Wet and dry density of soils are important values for geotechnical engineers in determining over-burden stresses, void ratios, maximum compaction and percent compaction of soils. Density value can also aid in the evaluation of soil strength and sensitivity. While reporting on soil density has been part of routine laboratory testing for years, there have been no standards that outlined procedures…
