摘要：

It has been shown that concrete can be produced entirely from waste products such as recycled concrete aggregates and fly ash. The recycled concrete gains strength very slowly probably due to pozzolanic reaction between fly ash and calcium hydroxide from the cement paste in the old concrete. It is suggested that the process may be used to upgrade the quality of demolished and crushed concrete for fill or road base purposes. © 1990.
