Abstract

Modified pozzolans and methods for making modified pozzolans that have desired chemical characteristics. The desired chemical characteristics are achieved by introducing one or more supplementary materials into the production plant that produces the pozzolans (e.g., usually as a waste material such as fly ash or slag). The supplementary material is incorporated into the pozzolan during its formation in the production plant and becomes an integral chemical constituent of the pozzolan. By forming the pozzolan with the desired characteristics in the production plant, the pozzolan can have optimal performance when blended with Portland cement for use in concrete.
