Would having pozzolans in my mix hinder the sealers results?
No. Although we know pozzolans use calcium to make more cement paste binder products. There is a timing issue. Most pozzolans do not become the most effective for 30 days of more from the day of pour. Typically concrete countertops are sealed within the first 3 weeks of their life, so there are plenty of hydration byproducts for the sealer to be effective. Plus there is plenty of hydration byproducts produced with properly cured concrete to go around.
