TIP 8 - Concrete Yield. Concrete batch weights are permitted to vary by ±1% on average. Aggregate moisture changes may result in as much as a 30 lb. variation in water content. Entrained air tolerances allow for as much as ±1.5% of the mix volume. Under ideal conditions the tolerance for yield is about ±1% for non-air entrained concrete and ...

weights are for dry aggregate, batch weights must be increased to main-tain the same dry cement-to-aggre-gate ratio. If aggregate batch weights aren’t adjusted to account for the moisture, you’ll get a lower yield (fewer units per pound of cement) and thus a less economical mix. To adjust aggregate batch weights, the moisture content of ...
