Green Point Rated Concrete

List members,
 
To reduce the use of virgin materials and to recycle, Build it Green is recommending that 25-50% of the portland cement used for residential foundation concrete be replaced by flyash or slag. What are your thoughts and implications on this recommendation? What percentage would you replace without concerns?
 
I am reluctant to replace any cement without some feedback.
 
Thank you for your input
