American Concrete Institute Method of Mix Design 11.3 (ACI Concrete Mix Design) 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 ACI mix design became the responsibility of ACI committee 211.
Four common mix design methods were used namely: American Concrete Institute (ACI), Department of Environment (DOR), Road Note 4 (RN4) and CPIIO. The Ibeto brand of Portland cement was used in the research and a characteristic strength of 20N/mm2 was designed for using the first four mix design methods. The concrete components used were tested
