This presentation summarizes use of pozzolans during a 55-year period in numerous concrete structures ranging from irrigation drain tile to a 5,000,000-cubic-yard dam. Photographs illustrate structures in which several types of pozzolans were used. Graphs comparing fly ash with natural pozzolans and control concrete show the superiority of fly ash concrete in most environmental tests. The magnitude of the fly ash marketing problem and the need for specifications for fly ashes derived from burning lignite and subbituminous coals are discussed. /Author/
