The American Concrete Institute. Founded in 1904 and headquartered in Farmington Hills, Michigan, USA, the American Concrete Institute is a leading authority and resource worldwide for the development, dissemination, and adoption of its consensus-based standards, technical resources, educational programs, and proven expertise for individuals and organizations involved in concrete design
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.
The following is a design guide for selecting proportions for initial concrete mix design for normal weight concrete. This guide references ACI 211.1-91 (Reapproved 2009), “Standard Pract for Selecting Proportions for Normal, Heavy weight, and Mass Concrete”, specifically Chapter 6, “Procedure” and Appendix 1, “Metric (SI) System
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.

acteristics of a concrete mixture is called mix design. Characteristics can include: (1) fresh concrete properties; (2) required mechanical properties of hardened concrete such as strength and durability requirements; and (3) the inclusion, exclusion, or limits on specific ingredients. Mix design leads to the development of a concrete
ACI METHOD OF PROPORTIONING CONCRETE MIXES The ACI Standard 211.1 is a “Recommended Pract for Selecting Proportions for Concrete”. The procedure is as follows: Step 1. Cho of slump
