Volcanic ash, in addition to its natural cementing properties, serves the purpose of a fine aggregate that fills the voids between the fine sand aggregate and the cement. In concrete made with volcanic ash as much as 50 percent of the cement may be replaced by the ash, although a smaller proportion commonly is used.
