1. A process for mixing a concrete batch to meet or exceed a predetermined compressive strength, the process comprising: a. recording an amount of water added to the batch; b. recording an amount of cement added to the batch; c. transmitting the amount of water added and amount of cement added to a processor; d. prior to pouring the concrete, calculating from the added water weight and added cement weight a batch water-to-cement ratio with the aid of the processor; e. prior to pouring the concrete, comparing the batch water-to-cement ratio to a desired water-to-cement ratio associated with concrete exhibiting the predetermined compressive strength according to a database of concrete family characteristics maintained on a computer; and f. prior to pouring the concrete, providing a notification of the predicted concrete strength.
