Fly Ash Facts for Highway Engineers. Fly Ash Use in: Concrete Base Flowable FillStructural Fill Grout Paving

摘要

Coal fly ash is a coal combustion byproduct (CCB) that has numerous applicationsas a engineering material; the annual production of CCBs is nearly 82 million metric tons (90 million tons). Since the first edition of Fly Ash Facts for Highway Engineers in 1986, substantial information has been accumulated regarding the use of fly ash. The purpose of this document is to provide technical information about engineering applications to potential users of CCBs and to advance the use of CCBs in ways that are technically sound, commercially competitive, and environmentally safe.
