Designing and Proportioning Normal Concrete Mixtures
For a severe freeze-thaw exposure, Table 9-5 recommends a target air content of 6.0% for a 25-mm aggregate. Therefore, design the mix for 5% to 8% air and use 8% (or the maximum allowable) for batch proportions. The trial-batch air content must be within ±0.5 percentage points of the maximum allowable air content.

Manufactured Sand vs. Natural Sand
The choice of fine aggregate, whether it is manufactured or natural sand, can greatly impact the fresh concrete properties of a mixture such as the workability, pumpability, and finishability. Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are well-rounded and are usually nearly spherical.
