American engineer (1880–1965)
Duff A. Abrams (1880–1965) was an American researcher in the field of composition and properties of concrete. He developed the basic methods for testing concrete characteristics that remain in use. A professor with the Lewis Institute, he studied the component materials of concrete in the early 20th century.
Abrams was researcher, professor, and director of the research laboratory of the Portland Cement Association in Chicago. He was elected in 1915 a fellow of the American Association for the Advancement of Science.[1] He was also president of the American Concrete Association (ACI) from 1930 to 1931. He was awarded the Frank P. Brown Medal in 1942.
Abrams investigated the influence of the composition of concrete mixes on the strength of the end product. Some of the results of his research were: the definition of the concept of fineness modulus; the definition of the water–cement ratio; a test method for the workability of a concrete mix by using what the Abrams cone. In a comprehensive research program, Abrams established the relationship between the water–cement ratio and the compressive strength of concrete. The results were first published in 1918 in D. A. Abrams, Design of Concrete Mixtures, Bulletin 1, Structural Materials Research Laboratory, Lewis Institute, Chicago, 1918.
