Quikrete Fast Setting Concrete Mix is a 50 lb bag of pre-blended cement, sand and gravel that sets hard in about 20 to 40 minutes and reaches walkable strength in roughly 4 hours. It needs only water added and is aimed at fence posts, mailbox posts, small slabs, steps and patching rather than structural work. Compared with standard Quikrete Concrete Mix, it cures much faster but gives you less working time, so you must place and finish it quickly. It is a practical choice for small jobs where you want to set posts and move on the same day.

Owners use it mostly for fence posts, mailbox posts and small patches and report it sets quickly and hardens reliably. The common complaint is the short working window, which punishes slow mixing and placement, especially in hot weather.
