Thanks Robert,
You wrote "On standard concrete you usually would not use more than 40% by weight. Flyash sets up slower but continues to build strength over time if there is sufficient calcium to bind with."
For us neophytes could you expand on this to tell whether the fly ash replaces 40% of concrete in a mix or constitutes 40% of the concrete in a mix.
Or "standard" concrete are you talking about a non-PC batch of concrete?
Thanks,
Ron
