Concrete is one of the most universal building materials there is. You can use it to create walls, create roads, and is an essential part of most construction sites. Since concrete is poured one way and ends up another, does that change in form have anything to do with how much one weighs>

How Much Does Concrete Weigh? Wet concrete and dry concrete have different weights, but they are not that different. The amount of concrete you have is not going to change too much. Water is essential to curing concrete, which makes it part of the included weight. That being said, a bucket of concrete, including the water needed to start the reaction is going to be more substantial than the initial bag of concrete that you can purchase at a store. Your ending result is going to mostly be the same amount give or take a few pounds for evaporation of the water.

You are watching: Weight of wet concrete vs dry concrete

With so many types of concrete, it can get confusing to know if wet concrete is heavier than dry concrete or vice versa. Knowing how concrete is formed is the first step to understanding more about the weight of the product in different stages.

How Much Does Concrete Weigh? Wet vs Dry

Concrete does not technically dry; It is just the result of a chemical reaction. Due to the makeup of concrete being a mixture of things, it can cause the cured concrete to become porous, which increases or decreases the amount of moisture in the finished product based on the humidity in the air. While you end up with a hard surface that you can walk on, there is still 95% of the moisture inside of your concrete that you originally started with. 

Depending on the region of the country you live in, your concrete could weigh more, both dry and wet. It all depends on the aggregates that are put into the concrete and where they are mined. Northwestern regions of the United States have some of the densest concrete in the country. 

Since concrete is comprised of different materials, not all concrete is going to weigh the same. The estimated weight of concrete is based on average weight. Basic concrete has an average weight of 116 pounds per cubic foot, but there is also lightweight concrete that can weigh less than 100 pounds or specialty concrete that can weigh over 300 pounds for the same amount.

Reinforced Concrete Weight

Reinforced concrete is concrete that is commonly used for large scale construction. Reinforced concrete is created using additional steel framing within the concrete to increase the strength of it. Due to placing steel or similar supports inside of reinforced concrete, the weight of the dry concrete is going to be higher than that of the wet concrete. Although the weight is more, it is usually no more than five to fifteen pounds per yard.

Lightweight Concrete Weight

Lightweight concrete is popular for those who are looking for a lighter alternative to traditional concrete. It is easier for some construction sites to use; it is more flexible and is an excellent absorber of sound and shock. Lightweight concrete I typically made from more porous materials. The highly porous formula can cause longer drying times, but the weight of the concrete will be relatively similar. With lightweight concrete, you do need to be more hyperaware of excess moisture, which can increase the weight of your concrete.

So, Which Weighs More?

The real answer is that they weigh pretty much the same. The only consideration in the weight of both dry and wet concrete boils down to a few factors. Where was it created, what kind of concrete is it, and how much water is required in order to create the necessary consistency? Knowing the answer to these questions can help you minimize the risk of having too much concrete or too little for your project. 

Since concrete retains almost all of the water that is used during the curing process, water is going to be an essential element in the weight of your concrete. With the average cubic foot of concrete weighing anywhere between 300 pounds to 100 pounds depending on the concrete used, it can make all of the difference in your project.
