ASTM International is developing a proposed standard that will help manufacturers of automatic guided industrial vehicles evaluate their products. In addition to manufacturers, vehicle buyers will use this standard (WK48955: Test Method for Docking and Navigation for Driverless Automatic Guided Industrial Vehicles) to conduct their own tests on potential purchases. ASTM member Roger Bostelman is…, Media Inquiries:, Nathan Osburn, tel +1.610.832.9603; nosburn@astm.org, Technical Contact:, Roger V.

ASTM International has launched a new technical committee, F45 on Driverless Automatic Guided Industrial Vehicles . After organizational meetings in October 2013 and January 2014, F45 was approved at the board of director’s recent spring meeting. In use since 1953, automated guided vehicles (AGVs) are defined by the Material Handling Institute (MHI) as “computer-controlled wheel-based load…, Technical Contact:, Roger Bostelman, National Institute of Standards and Technology, Gaithersburg, Md., roger.bostelman@nist.gov , ASTM Staff Contact:, Pat Picariello, Phone: 610-832-9720; ppicariello@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9650

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.…

A new test method developed by ASTM International Committee C01 on Cement provides information about the behavior of cement that can be used in the process of selecting cementing materials for specific applications. The standard, C 1608, Test Method for Chemical Shrinkage of Hydraulic Cement Pastes, is under the jurisdiction of Subcommittee C01.31 on Volume Change. Test Method C 1608 was…
