Abstract:
This TechNote discusses the implications of limits on the proportions of fly ash in project specifications. This TechNote addresses only fly ash that meets current, applicable specifications such as ASTM C618. Prescriptive specifications for concrete construction projects often include a clause that limits the proportion of supplementary cementitious materials (SCMs) (Obla and Lobo 2015).
