1. A method for monitoring at least one concrete mixing truck and its contents, comprising the steps of:
- determining a content status of at least one of a fleet of concrete mixing trucks wherein said content status is one of returning from a job site empty, returning from a job site with unused concrete, going to a job site and is currently empty, and going to a job site and currently contains unused concrete;
calculating a quantity of admixture, a quantity of water, and a quantity of other concrete ingredients depending upon the findings of said determining step; and

Abstract
An admixture dispensing and concrete mixer monitoring system which determines the correct amount of admixture, such as a stabilizer, to dispense in a load of unused concrete or for washing out a concrete mixer includes an admixture dispensing unit linked to a computer system. The computer system includes a processor which controls and monitors the operation of the dispensing unit which includes an admixture piping system and a water piping system. The processor is linked to various pumps, meters and valves in the admixture and water piping systems to control the flow of admixture and water into the concrete mixer. Additionally, the computer system provides questions and prompts to the user to assist in accurately and quickly determining the correct amount of admixture to deposit in the concrete mixer. The computer system also allows the tracking of multiple delivery or mixing trucks and their content status at multiple mixing plants to assist in the scheduling thereof.
