As rare earth materials play an increasingly critical role in the growth of global industries, an ASTM International subcommittee is gearing up to address challenges across the life cycle of these vital resources. ASTM Subcommittee F40.04 on Rare Earth Materials held its most recent meeting in April and has established a standards development agenda aimed at supporting efficient and safe…, Stimulating the Worldwide Supply Chain, The increased demand for rare earth materials has converged with supply bottlenecks, resulting in a looming shortage of these resources throughout the worldwide high-tech, energy and automotive sectors. To better ensure that rare earths are more readily available for industry use, public and private sector stakeholders are focusing on ways to diversify supplies. Strategies include improving…, Protecting Our Energy Future, Underscoring the importance of rare earth materials to clean energy growth, the U.S. Department of Energy has established the Critical Materials Institute (CMI) at its Ames Laboratory in Ames, Iowa. The institute will bring together leading experts from academia, national laboratories and the private sector to find solutions to help avoid a rare earth supply shortage. Dr. Alex King, director of…, ASTM Committee F40 Next Meeting:, Nov. 13-14, 2013, November Committee Week, Jacksonville, Fla., Technical Contact:, Taco van der Maten, PANalytical B.V., Almelo, The Netherlands, Phone: +31-546-534-372; taco.van.der.maten@panalytical.com, 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 #9406

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…
