Abstract
Reports the findings of an investigation of concrete structures built using pulverised-fuel ash (pfa) concrete. The age of the structures ranged from 2 to 33 years. In addition to pfa concrete, comparable ordinary Portland cement (OPC) concrete was available for sampling at all the locations chosen. A range of properties was measured on concrete cores taken from these structures. Generally, the pfa concretes showed superior properties to similar OPC concretes. These included greater strength, lower permeability, greater resistance to the ingress of chlorides, and a suppression of alkali-silica reaction.
