Concrete Manual: Certifying Ready Mix Concrete Mobile App
Ready-mix concrete shall meet the same general requirements as job mix concrete.
How does it work?
Since commercial plants supply other users during the same general period as they furnish the Agency with certified ready-mix concrete, the problem of good inspection is considerably more complicated than when using job mixed concrete. At the ready-mix concrete plant, the concrete aggregates may vary to a greater degree, both in moisture content and in gradation. The Concrete Manual: Certifying Ready Mix Concrete details the certification process.
