ANSWER: Keeping concrete moist helps the curing process. … If too much water is lost from the concrete through evaporation, the hardening process slows down or ceases. Concrete continues to gain strength after pouring for as long as it retains moisture, but the longer it moist-cures, the slower the rate of strength gain.

What is the best concrete to use for a driveway?

Portland Cement: Portland cement is a material commonly used to create concrete. It acts much like a strong glue, providing a reliable bond that makes it a popular choice for laying driveways and pathways. If you are mixing your own concrete, this will be an important component.

What happens if you don’t add enough water to concrete?

How strong is 6 inches of concrete?

For example, a 6-inch pad with a compression strength of 700 psi can support 1,105 psi. If it was 7 inches thick, it could support 1,194 psi, and if it was 12-inches thick, it could support 1,563 psi.

Does driveway need rebar?

Using steel reinforcement will provide additional structural capacity for your driveway and is especially important if the slab will be exposed to heavy traffic.
