Concrete Mix Design - The Concrete Network
The standard for designing a concrete mix is ACI 211.1, Proportions for Normal, Heavyweight, and Mass Concrete. Like most ACI committee reports, this document is excellent, albeit highly technical.
CONCRETE MIXING RATIOS - Everything About Concrete
The less water you use to mix the concrete (somewhat dry but workable) the stronger the concrete mix. Accurate concrete mixing ratios can be achieved by measuring the dry materials using buckets or some other kind of measuring device. By measuring the mixing ratios you will have a consistent concrete mix throughout your entire project.
Cement Standards and Concrete Standards - Standards Worldwide
Cement Standards and Concrete Standards ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.
Concrete: The Basic Mix
Another "old rule of thumb" for mixing concrete is 1 cement : 2 sand : 3 gravel by volume. Mix the dry ingredients and slowly add water until the concrete is workable. This mixture may need to be modified depending on the aggregate used to provide a concrete of the right workability. The mix should not be too stiff or too sloppy.

STANDARD SPECIFICATIONS for GENERAL CONCRETE CONSTRUCTION
The air content of the concrete shall be 6% plus or minus 1% by volume based on measurements made on concrete immediately after discharge from the mixer in accordance with ASTM, C-138, C-173 or C-231. 8. MIXING: Concrete shall be mixed in a batch mixer for not less than 1-1/2 minutes after all the materials are in the mixer drum.
Concrete mixer - Wikipedia
A variant of standard concrete transportation is the concrete or cement mixing trailer. These small versions of transit-mix trucks are used to supply short loads of concrete. They have a concrete mixing drum with a capacity of between 1 and 1.75 cubic yards (0.76 and 1.34 m 3). Cart-aways are usually pulled behind a pick-up truck and batched ...
