Concrete Batch Plant - Concrete Engineering general

Sep 10, 2007 · Hey all, I am looking for information on ready mix batch plants. The majority of batch plant inspections I have performed consists of going to plant, checking batch ticket for correct mix, weight tolerance on materials, calculating out allowable water to be added on job if any, requesting that the driver fills his water tank full, doesnt soup up the mix while washing fins and goodbye.
