How Long Can Concrete Sit in Truck

Concrete is an important building material for any construction project. Still, it must also be used fairly quickly after it is mixed. Otherwise, it will start to set and become unusable. In this blog post, we will discuss how long concrete can sit in the truck, what happens if the concrete dries in the truck, and other important information related to concrete trucks.


How long can concrete sit in the truck?

Under normal conditions, concrete has a usable life of about 1 1/2 hours. However, in summer, it will lose workability more rapidly. Ideally, it should be placed and finished within 1 hour of discharge from the truck mixer. After that, the concrete will start to set and will eventually become hard as a rock. If concrete sits in the truck for too long, it will begin to harden and become unusable. This will lead to some problems, including reducing the mixer’s capacity, weighing down the truck, and making it more difficult to clean out of the truck. To avoid these potential problems, it’s essential to ensure that concrete does not dry in the truck.

What happens if the concrete dries in the truck?

If concrete dries in the truck, it can lead to several problems. The build-up of concrete residue inside the drum will gradually reduce the mixer’s capacity, meaning less fresh concrete can be transported. The dry concrete residue will also weigh down the truck, making it more difficult to move and requiring more fuel. In addition, the dried concrete will be more challenging to clean out of the truck, eventually leading to corrosion and damage.

What happens with leftover concrete in the truck?

When it comes to concrete, the usual process is to produce the necessary amount for a project and then pour it all at once. However, there are times when concrete producers may end up with leftover concrete in their trucks. When this happens, the concrete is usually recycled. It can be used to make concrete blocks, which can be used for retaining walls or barricades. Leftover concrete can also be used to fill in low spots in a parking lot or driveway. In some cases, selling the excess concrete to other companies or individuals who can put it to good use is possible.

How do they clean the inside of cement trucks?

Cement trucks are essential for construction projects but can become filled with dirt, dust, and debris over time. If not cleaned regularly, this build-up can eventually lead to problems with the truck’s performance. Fortunately, there are a few different ways to clean the inside of a cement truck. Using a high-powered vacuum cleaner to suck up loose debris is one way. Another way is to use a power washer with special attachments to reach all the nooks and crannies. Finally, you can manually scrub the inside of the truck with brushes and cleaning solutions.

How heavy is a full concrete truck?

Concrete is an extremely heavy building material, with a full concrete truck weighing up to 66,000 pounds. A single cubic yard of concrete weighs approximately 4,000 pounds. The weight of concrete can pose a challenge for construction workers, as it can be difficult to move and place concrete blocks without the right equipment. In addition, the weight of concrete can also cause problems for buildings and structures not designed to support such a heavy load. As a result, it is essential to be aware of the weight of a full concrete truck before attempting to move or transport one.

Why do concrete trucks spin? 

The rotating drum of a concrete truck mixes the dry components, which are aggregate and cement, throughout the journey. Water is added to the mixture when the truck is a few miles from the job site to make fresh concrete for delivery. The drum continues to rotate as the mixture is unloaded into the chute, ensuring the concrete is new and usable when it arrives at the job site. The spinning also helps distribute the concrete evenly, which provides it sets properly and has a consistent texture. With this critical step, the concrete could be usable and of better quality.

How does concrete get out of the truck? 

Concrete is mixed in a large barrel inside the concrete truck and then transported to the worksite for pouring. The truck operator uses a chute or a long hose to pour the concrete into place. The chute method is best for ground-level pours. The truck operator positions the chute above the worksite and reverses the drum to eject the material onto the ground. The hose delivery method is used for taller pours, such as filling in a foundation or going up against multiple stories on a building site. The hose is fed from the truck barrel into place, and the concrete flows into the prepared area.

Why do cement trucks have extra wheels? 

Cement trucks have extra wheels to spread the weight of the heavy load. The lift axle is lowered to the ground by the driver using a button on the dashboard. This prevents road damage and makes it easier for the truck to maneuver. Additionally, the extra wheels provide stability and traction, making it easier for the truck to start and stop. Cement trucks can safely transport large loads of cement without damaging roads or putting themselves at risk.

What are cement trucks called? 

Concrete mixers come in various sizes, from small portable units to large trailers carrying up to 16 cubic yards (12 m3) of concrete. The truck-mounted concrete mixer is the most common type, available in different sizes to suit project needs. A mini concrete mixer towed behind a car, or light truck is used for small projects. For larger projects, such as building a new home or pavements, a truck-mounted mixer with a capacity of 8 to 16 cubic yards (6 to 12 m3) is required. The concrete mix is typically discharged into a chute at the truck’s rear, where it can be transported to the job site using a wheelbarrow or pump.


Mixer trucks are essential for transporting and mixing large amounts of concrete in construction projects. They ensure the concrete is mixed properly, which is crucial for a high-quality finished product. Mixer trucks play a vital role in the construction industry and are essential to any construction project.
