What is the best concrete mix for driveways?
The best concrete mix for driveways is at least 3500 psi compressive strength and 5-6 inches thick over compacted gravel and earth with awater to cement ratio
Water–cement ratios of 0.40 to 0.60 are more typically used. For higher-strength concrete, lower ratios are used, along with a plasticizer to increase flowability. Too much water will result in segregation of the sand and aggregate components from the cement paste.
