Bisphenol A, or BPA, is a high production volume chemical widely used in manufacturing polycarbonate plastics and epoxy resins that are used in many industries. Procedures described in a new ASTM International standard will be used for measuring BPA concentration in environmental media such as soils, sludges and biosolids. The new standard, ASTM D7858 , Test Method for Determination of Bisphenol…, ASTM Committee D34 Next Meeting:, Virtual meeting, Oct. 10-11, 2013, Technical Contact:, Lawrence Zintek, Ph.D., U.S. Environmental Protection Agency, Region 5 Chicago Regional Laboratory, Chicago, Ill., Phone: 312-886-2925; zintek.lawrence@epa.gov, ASTM Staff Contact:, Alyson Fick, Phone: 610-832-9710; afick@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9456

A new ASTM International practice provides a standard for preparing a mixture of cement paste that will simulate the shearing experienced by the cement paste in concrete. The new standard, ASTM C1738 , Practice for High-Shear Mixing of Hydraulic Cement Pastes, was developed by Subcommittee C01.22 on Workability , part of ASTM International Committee C01 on Cement . According to Chiara Ferraris,…

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…

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…

After a 35-year-absence, the natural cement industry is being revived and, along with it, a long-withdrawn ASTM International standard. Until it closed in 1970, the Century Cement Company in Rosendale, N.Y. was the last company to manufacture natural cement. Up to that point, Rosendale had been the center of the industry, the source of more than half of all natural cement produced in the U.S.…
