Natural gas from unconventional sources such as coal beds has become a common target of exploration. Now, a new ASTM standard is the first to describe a method for determining the gas content of coal from such sources by desorption, using samples obtained by surface drilling. ASTM D7569 , Practice for Determination of Gas Content of Coal - Direct Desorption Method, was developed by Subcommittee…, ASTM Committee D05 Next Meeting:, May 15-18, 2011, May Committee Week, Anaheim, Calif., Technical Contact:, Peter Warwick, U.S. Geological Survey, Reston, Va., Phone: 703-648-6469; pwarwick@usgs.gov, ASTM Staff Contact:, Scott Orthey, Phone: 610-832-9730; sorthey@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8749

Moisture, volatile matter and ash are three of the primary parameters used for assessing the quality of coal. A new ASTM standard that covers the use of a macro thermogravimetric analyzer for the determination of moisture, volatile matter and ash in analysis samples of coal and coke has recently been approved by ASTM International Committee D05 on Coal and Coke. ASTM D7582 , Test Methods for…, ASTM Committee D05 Next Meeting:, May 16-19, May committee week, St. Louis, Mo., Technical Contact:, John T. Riley, Ph.D., Western Kentucky University, Bowling Green, Ky., Phone: 270-842-2757; brgrileys@insightbb.com, ASTM Staff Contact:, Scott Orthey, Phone: 610-832-9730; sorthey@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8 508/Feb2010

Rapid hardening hydraulic cements are used in a variety of applications in which reduced cementitious contents are desired or early service is needed. Included among these applications are paving, construction, stucco, mortar and block. A newly approved ASTM International standard covering these cements, ASTM C1600/C1600M , Specification for Rapid Hardening Hydraulic Cement, has been developed by…, Type URH, —ultra rapid hardening, for use where ultra high early strength is desired;, Type VRH, —very rapid hardening, for use where very high early strength is desired;, Type MRH, —medium rapid hardening, for use where mid-range rapid hardening, high early strength is desired; and, Type GRH, —general rapid hardening, for use when the higher strength properties of Type VRH or a Type MRH cement is not required. “ASTM C1600 lists minimum requirements for compressive strength, setting time, shrinkage and soundness (autoclave expansion),” says Hicks. “Optional specifications for sulfate expansion, alkali silicate reactions with aggregates, heat of hydration and expansion in water are also…

Measuring the reflectance of vitrinite dispersed in sedimentary rocks is one of the most commonly used tools for determining thermal maturity in hydrocarbon exploration, basin modeling and other geological applications. Despite this, there currently is not a consensus standard for making these measurements. ASTM International Committee D05 on Coal and Coke is developing a proposed standard to…

A recently approved revision to ASTM International standard C 150 , Specification for Portland Cement, includes three significant technical changes to the document. The changes are part of a joint effort between ASTM and the American Association of State and Highway and Transportation Officials to harmonize C 150 with AASHTO’s standard, M 85, Specification for Portland Cement. C 150 is under the…
