tures (for example, foundations and dams) to control temperature rise. In recent decades, research has demonstrated that high dosage levels (40% to 60%) can be used in structural appliions, producing concrete with good mechanical properties and durability (Marceau 2002). Increasing the amount of fly ash in concrete is not without shortcomings. At high levels problems may be encountered with ...
