Abstract:
This proposed standard is intended as a supplement to ACI Standard Recommended Practice for Selecting Proportions for Concrete (ACI 613-54). 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 -l/2 in. maximum size. Suitable equipment for measuring such consistencies is described. Tables similar to those in ACI 613-54 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 613-54, are given.
