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…

When ASTM International Committee F38 on Unmanned Aircraft Systems was formed in 2003, it is safe to say no one on the committee was thinking about catapults and trebuchets. However, a study of these medieval devices was integral to the development of a new F38 standard, F 2585 , Specification for Design and Performance of Pneumatic-Hydraulic Unmanned Aircraft System (UAS) Launch System. F 2585…

After a 35-year-absence, the natural cement industry is being revived and, along with it, a long-withdrawn ASTM International standard.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