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,…

While the use of digital evidence is fairly common in contemporary criminal investigation, there are still relatively few degree programs in computer forensics. A new standard developed by ASTM International Committee E30 on Forensic Sciences provides a road map for post-secondary institutions to develop degree programs in computer forensics. The new standard, ASTM E2678 , Guide for Education and…

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…

After a 35-year-absence, the natural cement industry is being revived and, along with it, a long-withdrawn ASTM International standard.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…
