Abstract: Disclosed is a method and apparatus for dispensing a user-defined quantity of one or more liquids for use in a cementitious mixture. The method includes moving a liquid from a liquid supply to a manifold; moving the liquid from the manifold to a flow meter; measuring the liquid while it moves through the flow meter; moving the liquid to a cementitious mixture; repeating these steps for any additional liquids; flushing any remaining liquid from the manifold with a purgative fluid; and moving purgative fluid and flushed liquid to the cementitious mixture.

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.
