Method of supplying admixture formulations for concrete

A method for an admixture producer to service the needs of concrete producers in producing concrete having desired concrete performance characteristics, said method comprising:

• (1) inputting technical information including at least one member selected from the group consisting of desired performance characteristics, a mix design, or a mix design code into a computer control system, wherein the technical information is inputted into the computer control system by the concrete producer, (2) determining types and levels of admixture raw materials that are needed to attain the desired concrete performance characteristics, (3) dispensing the types and quantities of admixture raw materials needed to produce an admixture having the properties needed to attain the desired concrete performance characteristics, wherein the admixture raw materials are dispensed from an inventory of admixture raw materials that is maintained in proximity to a concrete mixing facility of the concrete producer, and (4) invoicing the concrete producer for the service provided, wherein the invoice includes a charge based on the volume of the concrete produced times a base price, wherein the base price is selected from a group of base prices, wherein the base prices are based upon the concrete performance characteristics of the concrete produced, and wherein the base prices have been previously agreed upon by the admixture producer and the concrete producer.

A method for an admixture producer to provide admixtures to a concrete producer, said method comprising:

• (1) inputting technical information including at least one member selected from the group consisting of desired performance characteristic, a mix design, or a mix design code into a computer control system, wherein the technical information is inputted into the computer control system by the concrete producer, (2) determining types and levels of admixture raw materials that are needed to attain the desired performance characteristics, (3) dispensing the types and quantities of admixture raw materials needed to produce an admixture having the properties needed to attain the desired performance characteristics, wherein the admixture raw materials are dispensed from an inventory of admixture raw materials that is maintained in proximity to a concrete mixing facility of the concrete producer, and (4) invoicing the concrete producer for the admixture, wherein the invoice includes a charge based on the quantity of at least two admixture components dispensed as the admixture, wherein the charge is based upon the volume of admixture components dispensed multiplied by a base price, wherein the base price is selected from a group of base prices for said admixture components, and wherein the base prices have been previously agreed upon by the admixture producer and the concrete producer.
