What is 5 bag mix, 6 bag mix, 3000 PSI, 3500 PSI, 4000 PSI ...
We recommend a 6-1/2 bag mix or 4,000 PSI concrete with a 6-8% air entrainment and low slump in the 3-4“range to avoid Spalling of the surface from the winter. Then depending on the weather conditions, one might add fiber-mesh and a retarder to help the workability of the concrete and avoid shrinkage cracks.Learn More

After research, we decided on a very strong mix of one part cement, two parts sand and three parts gravel – a 1-2-3 mix, except for floors where we used 1-2-4. This also led us to buy a gas powered one-bagger cement mixer, a gas powered internal concrete vibrator and to stick with the 1-2-3 concrete mix.Learn More
