Answers: Which concrete mix is the best for pouring small outdoor pads?

• pouring concrete pads
• Quikrete 5000
• Quikrete Fast-Setting
• Rapid Set Concrete Mix
• concrete forms and leveling
• concrete mixing and finishing

What it concludes

• Quikrete 5000 is a solid basic concrete that works great and provides a nice surface finish, though it takes 28 days to reach full strength.
• Quikrete Fast-Setting sets hard in 20 to 40 minutes, but it is prone to voids and rough edges if not mixed and vibrated properly.
• Rapid Set Concrete Mix is very easy to work with, sets in 15 minutes, achieves full strength in 1 hour, and leaves a smooth, solid finish when sufficient water and time are used.
• Rapid Set is the best overall choice for ease of use and quick setup despite being more expensive.
