To calculate the yardage capacity of a concrete truck, you can use the following method:

• Identify the truck’s barrel volume. This information is typically available from the manufacturer or the supplier.
• Understand that the maximum capacity of a concrete truck is not its barrel volume due to safety and legal weight limits. Trucks usually carry about 10 cubic yards of concrete, but this can vary based on the truck’s design and local regulations.
• Apply the standard fill rate (usually between 60% to 75% of the barrel volume) to determine the working capacity.

Knowing to calculate this yourself can empower you to make informed decisions, ensure accuracy in your planning, and serve as a check against the information provided by suppliers.

## Factors that affect the yardage capacity of a concrete truck

Several factors can influence the yardage capacity of a concrete truck:

1. Truck Size and Design:
• Concrete trucks come in various sizes and designs, with standard trucks generally holding between 9 to 11 cubic yards. The design of the drum also affects capacity.
2. Legal Weight Limits:
• There are legal limits to how much weight a truck can carry on public roads. Since concrete is heavy, these weight limits may restrict a truck’s yardage capacity.
3. Concrete Density:
• Different concrete mixes have varying densities, which can affect the total weight of the concrete a truck can legally carry.
4. Maneuverability:
• Smaller trucks that can navigate tight spaces may carry less concrete to meet maneuverability needs.
5. Local Regulations:
• Different jurisdictions may have regulations that impact truck capacity, such as restrictions on total vehicle weight, which in turn affects how much concrete can be transported.

• The conditions at the construction site can also dictate the size of the truck used. Smaller trucks might be required for sites with limited access or where space for maneuvering is tight.
7. Delivery Distance:
• Longer delivery distances can affect the volume of concrete a truck carries to ensure it remains within legal weight limits and to reduce the risk of the concrete setting in the mixer.
8. Concrete Slump:
• The slump, or fluidity, of the concrete mix, can influence the amount a truck can carry. A higher slump mix is more fluid and can settle more, potentially allowing for more volume.

Understanding these factors can help in planning and ensuring that concrete delivery is optimized for both efficiency and compliance with regulations.

## Common misconceptions about concrete truck capacity

Yes, there are several common misconceptions about concrete truck capacity that can lead to confusion or mismanagement in construction projects:

1. Full Barrel Equals Full Capacity:
• It’s often assumed that a concrete truck can carry a full barrel of concrete. In reality, due to weight restrictions and safety concerns, the actual amount of concrete a truck can legally transport is typically less than the mixer’s full volume.
2. One Size Fits All:
• People might think all concrete trucks have the same capacity. However, there’s a range of sizes and capacities available, from smaller trucks that carry fewer cubic yards to larger ones designed for substantial pours.
3. Capacity Equals Delivery Volume:
• Some believe the capacity listed by the manufacturer is the same as the delivery volume. The manufacturer’s capacity often refers to the mixer volume, not the amount of concrete the truck is capable of carrying once water and concrete mix have been added.
4. Weight Doesn’t Matter:
• There’s a misconception that as long as there’s space in the mixer, it can be filled with concrete. The weight of the concrete, not just the volume, is a critical factor due to legal weight limits for trucks on public roads.
5. All Mixers Can Carry Maximum Loads:
• The assumption that mixers can always carry the maximum load without issue ignores the fact that different concrete mixes have different weights and that road conditions and gradients also affect how much a truck can carry.
6. Unchanged Capacity Across Distances:
• Some might not realize that the truck’s capacity may need to be adjusted for longer distances to prevent the concrete from hardening during transit or to conform to weight limits that vary from one jurisdiction to another.

By dispelling these misconceptions, project managers and crews can better plan their concrete needs, schedule deliveries more accurately, and avoid costly mistakes or delays.

## Different types of concrete trucks and their yardage capacity

Certainly, the type of concrete truck selected for a project greatly influences its yardage capacity. Here’s a look at some common types of concrete trucks and their typical capacities:

1. Standard Concrete Mixer Trucks:
• These are the most common trucks seen on construction sites. They have a rotating drum on the back and come in varying sizes. The capacity of these trucks is usually between 9 to 11 cubic yards of concrete. However, they are bound by weight restrictions, which can reduce the volume of concrete they carry.
2. Volumetric Concrete Mixers:
• Unlike standard mixers that carry pre-mixed concrete, volumetric mixers store the separate components of concrete (cement, water, sand, and gravel) and mix them on-site. This means they can carry more material in total, but the yardage of mixed concrete ready to pour is comparable to standard mixers. They are particularly useful for projects where the concrete needs to be customized or when the site is far from a batching plant.
3. Mini Mixers:
• Mini mixers are smaller in size, which allows them to maneuver in tight spaces where larger trucks can’t access. They typically carry around 3 cubic yards of concrete, making them suitable for small residential projects.
4. Trailer-Mounted Mixers:
• These mixers are towed behind a truck and are used for smaller volumes of concrete, usually around 1 to 2 cubic yards. They are ideal for very small projects or when there’s a need for occasional concrete placement.
5. Concrete Pump Trucks:
• While not mixers themselves, these trucks have a pump and a boom that can transport concrete from mixer trucks to the specific location where it is needed on the site. The capacity of the mixer truck feeding the pump would determine the yardage.
6. Semi-Trailer Mixers:
• These are larger-capacity mixers that are pulled by a tractor unit. They can hold larger quantities of concrete, sometimes up to 15 cubic yards or more, but are subject to the same weight limitations as other types of mixers.

Each type of concrete truck serves a specific need depending on the project size, the volume of concrete required, the delivery location, and the type of mix needed.

Knowing the capabilities and limitations of each can help ensure that the right type of truck is used for each job, optimizing both cost and efficiency.
