Typical use cases
- Every concrete pour — matched to member size and pumping method
On-site best practices
- Pick size by section: max aggregate ≤ 1/4 of the thinnest member and ≤ spacing between bars
- Wash dusty aggregate — dust coating kills bond and adds hidden fines
Storage & handling
- Separate sizes with bulkheads; a mixed stockpile can't be un-mixed
- Stack on hard ground away from mud runoff
Care & maintenance
- Drain stockpiles after rain; free surface water changes the mix water
