FHWA Task 56-B - Concrete Mixture Optimization Using Statistical Mixture Methods

Date Started: 1999

Date Estimated Completion: 2001

Budget: $66,000

Sponsor: Federal Highway Administration, Washington, DC

Performing Organization:

TFHRC
NIST, Building Materials Division

Description: Objectives are to: 1) To investigate the feasibility of using statistical experimental design methods in concrete mixture proportioning, and if feasible; and 2) To develop an interactive website that will assist interested parties in using these methods. In Phase I of the project the design, performance and analysis of two laboratory experiments to identify one or more concrete mixtures, which meet several performance criteria at minimum cost, will be conducted. Several statistical approaches will be tried. If one of the approaches proves feasible, an interactive website will be developed to help the user select trial batches.
