Mix design versus batching

Mix design versus batching

(OP)
Hello batchmen and technical services guys,

From your experience, how closely do the physical batches (batch ticket materials and weights) match the mix design? I guess water and chemicals can be variable and depends how automated your operations are? But otherwise what would you ballpark? Is this back-able by hard data?

Thanks!
Asmile

RE: Mix design versus batching

They physical batches are fairly accurate... within a few percent, generally. The biggest problem, I think, is the moisture content of the sand and coarse aggregate.
