When it comes to waiting for concrete to harden, the standard time frame given is 24 to 48 hours. But there are several factors that can affect that schedule. A concrete contractor understands what conditions are optimal for both hardening and full concrete curing. Below, the team at Central Pacific Specialty Contractors of Aiea, HI, shares some of this knowledge.

3 Factors That Can Affect Concrete Set Time

1. Moisture

When mixing cement, contractors know it’s important to use a precise amount of water. If the mix is too dry when poured, it can set too fast and compromise the strength of the finished product. If too much water is added, the hardened cement will be prone to flaking.

Even when the cement is mixed perfectly, weather conditions can affect the drying process. If rain starts to fall at any point in that 24- to 48-hour window after the cement has been poured, it could cause the cement to set incorrectly and weaken. This can usually be avoided by covering the concrete with a tarpaulin.

2. Temperature

The optimal temperature for concrete hardening is between 50 and 90 degrees. Hot weather can accelerate the drying time but severely compromise the final product. If the weather is too cold, the concrete may crack. A reliable contractor knows it’s best to wait for better weather conditions or make use of an insulated blanket to protect the cement while it dries.

3. The Mix Used

Finally, the type of cement being poured will influence the time it takes to set. Some mixes come with accelerants to speed up the hardening process. But these aren’t always the best option since they can weaken the cement. If you’re simply pouring a patio that will only take foot traffic, this might be what you need. But if you need a new driveway, go with the sturdier option.
