In order to determine whether or not the concrete meets specification requirements for cement content, water-cement ratio, etc. the Inspector must know the exact amount of materials used in mixing the concrete. The equipment used for proportioning the various ma terials in the batching operations shall comply with Specifications 1901.8 and 2461.4B.
Mass balances take several forms. In some systems, no material enters or leaves the CV, and the rate of change is not considered important. In such systems, the mass balance simply states that everything that was present in the system at some initial time must be there at all later times, albeit perhaps in different forms.
