CTS notes passing of Type K cement developer E.H. Rubin

CTS Cement Manufacturing Corp., Cypress, Calif., reported last month the death of longtime consultant, Edward H. Rubin, at the age of 87, emphasizing his “skill and knowledge of cement and concrete [as] invaluable in the early development of shrinkage compensating cements.”

An American Concrete Institute Fellow and founding member of ACI Committee 223, source of “Standard Practice for the Use of Shrinkage-Compensating Concrete,” Rubin earned a B.S. in civil engineering from the University of Southern California. After graduating cum laude in 1951, he joined the California Division of Highways as junior engineer, then the Los Angeles Flood Control District as head of the Construction Material Section. In 1963, he joined Chemically Prestressed Concrete Co., developing Type K expansive cement as its technical director. From 1971–1992, he worked for Twining Laboratories, capping his tenure as president before transitioning CTS as a consultant.

Rubin effected a program of applied research and development on expansive cements, and invented methods of testing and measuring restraint of expansion, now used in ASTM C806 Standard Test Method for Restrained Expansion of Expansive Cement Mortar and C878 Standard Test Method for Restrained Expansion of Shrinkage Compensating Concrete. The latter references a concrete mold named for him, the Rubin Bar.
