The objective of this project is to document the use of pozzolanic materials in concrete used in infrastructure projects and prepare reports on the state of practice of pozzolanic concrete in infrastructure projects and in federally funded infrastructure projects. The latter report shall be prepared in a format appropriate for submission to the U.S. Congress. The research shall consider the use of fly ash, silica fume, and other pozzolans, both singularly and in combination. The documentation shall include the criteria and methods used to assess suitability of these materials for use in concrete structures, e.g., concrete properties such as durability and strength, estimated service life, economic considerations, and environmental impacts. For this project, pozzolanic concrete is defined as concrete containing pozzolanic materials. The research shall consider FHWA funded projects, projects located on federal lands, and projects using the formula and discretionary grants funds.
