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…

The presence of lead in toys and other consumer products continues to make headlines. The Consumer Product Safety Improvement Act, a United States law enacted in August 2008, addresses the lead issue and makes provisions for the use of X-ray spectrometry in testing for lead content. To aid the toy and consumer products industries in using X-ray spectrometry for lead detection and meet the…

Developing Standards for REACH, RoHS and Similar Regulations Implementation, ASTM International Committee F40 on Declarable Substances in Materials will meet April 15-17, 2008, at the Renaissance Hotel in Brussels, Belgium. The purpose of the meeting is to continue developing the international standards needed in response to REACH and RoHS implementation. , REACH, RoHS and ASTM Committee F40, The European Union’s Restriction of Hazardous Substances (RoHS) directive and Registration, Evaluation and Authorization of Chemicals (REACH) system — designed to help improve human health and the environment — affect companies and consumers throughout the global supply chain for manufactured goods. ASTM International Committee F40 develops the standards to help stakeholders with the…, Meeting Highlights, On Tuesday, 15 April, , Subcommittee F40.01 on Test Methods will review five proposed work items, among them WK11200 , Standard Test Method for Identification and Quantification of Lead, Mercury, Cadmium, Chromium, and Bromine in Polymeric Material Using Energy Dispersive X-ray Spectrometry (EDXRF). WK11200 will assist industry throughout the polymeric supply chain by testing the materials at the raw material level.…, On Wednesday, 16 April, , Subcommittee F40.02 on Management Practices and Guides will continue drafting WK15430 , Standard Guide for European Union's Registration, Evaluation, and Authorization of Chemicals (REACH) Supply Chain Information Exchange. WK15430 is being developed to assist industry with communications through the supply chain for REACH compliance. Providing a standard way to communicate will save money and…, On Thursday, 17 April, , A workshop on REACH will be held. Workshop speakers include meeting co-sponsor and Committee F40 vice chairman Taco Van Der Maten of PANalytical; meeting co-sponsor Dirk Wissmann of SPECTRO Analytical Instruments, a division of AMETEK Inc.; and Kristina Nordlander in Sidley Austin’s Brussels office. A question and answer session will cap off the event. , Open Participation, Participation in ASTM Committee F40 is open to all interested stakeholders. The committee draws on the expertise of an international group of stakeholders representing trade associations, manufacturers, government regulators, consumers and academia, and encourages and promotes publications, research and other tools to facilitate RoHS and REACH compliance and standards development.
