 · Field investigation of highvolume fly ash (HVFA) concrete in pavement construction was carried out. Test results performed on cores drilled from pavement after 270 days of concrete age showed that use of HVFA results in production of pavement concrete with improvements in: strength; moisture barrier qualities; and abrasive resistance characteristics.

Most high filler concrete studies are based on relatively high contents of powder (cement + filler) (>400 kg m3). This paper aims to increase the total fly ash content relative to the clinker content, while simultaneously minimizing the total powder content in the concrete to values lower than 300 kg m3. The motivation for decreasing the total powder content using fly ash as a cement ...

 · Fly ash to be used in Portland cement concrete (PCC) must meet the requirements of ASTM C618. (5) Two classes of fly ash are defined in ASTM C618: 1) Class F fly ash, and 2) Class C fly ash. Fly ash that is produced from the burning of anthracite or bituminous coal is typically pozzolanic and is referred to as a Class F fly ash if it meets the chemical composition and physical requirements ...

 · The highvolume fly ash concrete used in the Liu Centre show a rather low autogenous temperature rise8. Several investigations have shown that the autogenous temperature rise of highvolume fly ash concrete was about 1525°C less than that of a reference concrete without fly ash. This is an advantage where thermal gradient and stress are an issue.
