Setting Posts and Pouring Slabs with Fast Setting Concrete

About Fast-Setting Concrete. Fast-setting concrete, such as Quikrete® Fast-Setting Concrete Mix, simplifies and speeds up setting posts and pouring small slabs. The mix sets hard in just 20 to 40 minutes versus the 24 to 48 hours of traditional concrete. This allows homeowners to level and adjust their projects quickly.

Concrete curing time & psi

Well, Jeff, I'm not in the concrete industry so I can't speak scientifically, but as a contractor it seems the difference is mostly in the amount of cement in the mix (pea-gravel 6-sack mix is 2000 psi, 6-1/2 sack is 2500 psi), but I believe the aggregate size affects strength as well; 1" gravel is what L.A. Public Works requires for sidewalks and curbs.

Concrete Curing Compounds

Curing compounds (cures) are liquid membrane-forming compounds that reduce moisture loss in the early hardening period when applied to fresh concrete. A curing compound helps retain moisture in the concrete, improving hydration. This improved hydration produces a stronger, denser concrete substrate when compared to improperly or uncured concrete. The curing …
