2015-1-13 American Concrete Institute Method of Mix Design (ACI–211.1) This method of proportioning was first published in 1944 by ACI committee 613. In 1954 the method was revised to include, among other modifications, the use of entrained air. In 1970, the method of mix design became the responsibility of ACI committee 211.
