Fremont Cement Drying

Concrete dry times vary, but when the conditions are conducive, concrete takes between a day and two to dry enough for you to drive and walk on it. However, for the concrete to achieve its full effective strength, the concrete drying time is about 28 to 30 days.

In this article, we will cover more about the concrete cure and dry time. Contact Fremont Concrete Pros at (510) 683-5860 for more details about cement curing and drying in Fremont.

Duration of Cement Curing

In case you are not aware, concrete curing maintains the right moisture levels in the concrete mix after it is poured. A successful concrete curing process allows the concrete to reach its maximum strength. This reduces the risk of concrete developing cracks and other issues. 

Concrete never really cures completely, but it does harden each day as the days go by. In 48 hours, the cement is usually hard enough to drive and walk on it, and by seven days, it is cured to about 70 percent. There are always some traces of moisture in the concrete, but within 28 days or so, it achieves its "full strength."

Factors Affecting Cement Cure Time 

If you are asking yourself, how long does cement take to cure? Several factors affect the concrete/cement cure/dry time, and some of them include:

Level of Moisture 

Among the most important parts of the concrete drying process is the level of moisture in the concrete. If the moisture is too much, the top layer of the concrete will be weak, which can lead to flaking. If the moisture is too little, the curing process will not be thorough enough, and this can make the concrete weak. 


The weather in your place can speed up or slow down the concrete drying process. If you are in hotter areas, the moisture will evaporate faster. It is essential to keep your concrete moist using water in areas with high temperatures to avoid risking, not curing the concrete as it should be. 

You might want to cover your concrete with a concrete blanket in colder areas to make it hotter, hence cure faster. 

Mix Design 

Some accelerants can be added while the concrete is mixed with speeding up the concrete drying time and curing time. However, while these accelerants can speed up the drying time, they can affect the concrete's strength. It is always wise to let your concrete dry and cure normally. 

How to Protect Your Freshly Laid Concrete 

There are various things you can do to protect your concrete and ensure it cures normally. For example, you can use plastic sheeting to cover the concrete in cold areas. Apart from that, some specialized oils and compounds seal the surface to ensure the right amount of moisture is retained. 

Be sure to be up to date with the weather in your area. If it is going to be hot, moist the concrete with water from time to time to ensure the right hydration is kept. If it is going to be rainy, be sure to cover the concrete to avoid excess moisture into it. 

Difference Between Concrete Drying and Concrete Curing

Concrete drying and curing are two different processes. The concrete curing process takes about a month, and it begins immediately after the concrete is poured. 

However, even after your concrete has been cured, it may take way longer for all the excess water to be evaporated. While concrete curing time is about 28 days, concrete drying time can be much longer. Sometimes it takes months. If all factors are kept constant, it takes about a month to dry an inch of slab thickness. 

How Concrete Cures

Although there are different concrete types, they all contain three basic elements: aggregate, water, and cement. When you mix water and cement, a chemical reaction occurs, and that's what binds them together and causes concrete to harden. With time, the concrete becomes porous, and some amount of water in it becomes part of the concrete. The other water either remains in the capillaries of the concrete or evaporates. 

How Concrete Dries 

Concrete dries when the water inside it evaporates through the concrete's surface. As the water evaporates through its surface, the water from deep within it moves via the capillaries to replace it. And as long as the area can hold more vapor, the evaporation continues. The evaporation only stops if the surrounding area cannot hold more water vapor, and that's when concrete drying stops. 

How Do You Know Your Concrete is Dry?

You cannot know if your concrete is dry unless you have it tested. The most suitable way of testing if the concrete is dry is through the situ relative humidity test. Knowing concrete drying problems can help correct them before they cause significant loss.
