The 28-Day Myth - National Precast Concrete

28-10-2013  Ensuring concrete reaches the minimum required compressive strength is not enough to ensure it will perform as required for the duration of its service life. A concrete mix could achieve a 5,000 psi compressive strength, but may not perform well in service because of the type, quantity or proportions in which the other raw materials are used.

Why Strength Matters in Concrete Countertops

Concrete with standard aggregate needs to be about 5,000 psi to take a very high polish. Concrete with Limestone aggregate needs to be about 5,500 psi to take a decent polish. 4. For sealers. The majority of topical concrete sealers need a bit of penetration and a mechanical bond with the concrete in order to not delaminate. They will bond fine to 3,000-psi concrete polished to 200 grit.
