sand was used as the fine aggregate. The Class F fly ash retarded the strength gain at early ages, particularly when the concrete was cured at low temperatures; however, maintaining the cement content mitigated this effect. ASTM C 1293 data showed that in some cases addition or partial substitution of Class F fly ash for the cement was

In our sector, fly ash is either put in the cement by the cement producer or it is mixed in at the concrete plant. HeidelbergCement, with operations both in cement and concrete production, has taken a strategic choice to add the fly ash in the cement. We believe this has several advantages. Adding fly ash to a cement mill leads to a more homogeneous cement binder.
