This standard is intended as a supplement to ACI Standard "Recommended Practice for Selecting Proportions for Normal and Heavyweight Concrete (ACI 211.1-74)." The standard describes a procedure for proportioning concretes having slumps in the range of zero to 1 in. and consistencies below this range, for aggregates up to 1 1/2 in. maximum size. Suitable equipment for measuring such consistencies is described. Tables similar to those in ACI 211.1-74 are provided which, along with laboratory tests on physical properties of fine and coarse aggregate yield information for obtaining concrete proportions for a trial mixture. Examples of the use of these tables, in conjunction with tables in ACI 211.1-74 are given. An appendix provides complete conversion of all tabular data to metric system units and shows a sample problem worked out with metric values.
