A concrete truck is a large vehicle used to deliver cement. They come in different styles, including front discharge trucks and rear discharge trucks. Rear discharge trucks have a chute at the rear and require a driver and chuteman to operate. The front discharge trucks have controls inside the cab and can move the chute in all directions. The first front discharge mixer was designed by Royal W. Sims of Holladay, Utah.
A concrete truck can be front load or rear load, have different wheel sizes, and can hold eight to fourteen yards of concrete. There are also “mini” trucks with four wheels and four yards of concrete. Larger concrete trucks have eight wheels and are more than 14 feet tall. While they are heavy, they also can hold 14 yards of concrete.
A concrete truck driver is known as an agi driver. He knows how to properly mix the concrete to ensure that it reaches the right consistency and strength. He must also understand the slump of the concrete. The wrong slump can make the concrete difficult to work with on site.
How Does a Ready Mix Truck Work?
A ready mix truck driver is responsible for delivering concrete to the job site. Besides unloading materials safely, they must also perform various maintenance duties and inspections on the truck. These include removing buildup from the mixing and delivery apparatuses. Ready mix truck drivers can either work for a concrete delivery service or independently.
A ready mix truck works by delivering a ready-mixed concrete from a batch plant to the construction site. Sometimes, it is also called a cement mixer truck. In its basic form, it’s a truck with a rotating barrel that mixes concrete as it travels.
The process of making concrete involves mixing cement, aggregates, and water. The ratio of these materials determines the strength and integrity of the final product. Concrete is a mixture of Portland cement, water, and sand, gravel, and crushed stone. The transit mixer truck uses a mechanical device called an Archimedes screw to mix the components of the concrete mix. The screw turns in a counterclockwise motion to mix the cement, aggregates, and water.
How Many Cubes are in a Ready Mix Truck?
The most common Ready Mix Truck (RMC) can carry anywhere from eight to eleven cubic yards of concrete. Smaller trucks can carry as little as five cubic yards of concrete. Most RMC trucks are designed to carry lighter loads, typically eight to eleven cubic yards, due to road regulation limits. The concrete is placed in drums that rotate slowly during transportation to prevent setting up during travel.
When ordering concrete, remember to take the dimensions of the concrete slab. This will help you determine how many cubic yards you’ll need. Once you know your exact measurements, multiply the length, width, and height by 27 to get the cubic yardage. You can also use an online concrete calculator to determine the amount of concrete you’ll need. If you’re a contractor, it’s important to choose the right type of concrete delivery because it will affect the cost and the amount of concrete you order. If you need a large amount of concrete, consider ordering by the truckload, instead of by the cubic yard.
When looking to order concrete, look for a ready mix truck that meets your specifications. A typical ready mix truck will hold about six to ten cubic meters of concrete. It will have compartments for the essential ingredients for concrete production, including additives and air entrainment. The operator will adjust settings to produce a concrete mix. The ingredients are then dropped into a pot at the back of the truck. An auger will mix the ingredients together.
What is RMC Truck Called?
A Ready Mix Concrete truck is used for construction projects. It carries concrete that has been mixed at the job site. The concrete rotates at a speed of two revolutions per minute during transit and at 12 to 15 rpm upon arrival. This allows the concrete to be evenly mixed, while minimizing transit time, which can cause hydration and render the concrete unusable.
Unlike traditional concrete trucks, RMC trucks are equipped to do all the mixing. Truck mixers are designed to be quick to position a full load in fifteen to thirty minutes, representing a delivery rate of almost 30 m3 per hour. RMC trucks also deliver concrete with the appropriate workability. If it is outside of a specified tolerance, the concrete may need to be adjusted with an Admixture or rejected.
RMC is an expensive material. It’s formulated in a plant, then mixed in a truck mixer. The RMC truck then delivers the concrete to a construction site in ready-to-place condition. A RMC truck, which is also referred to as a Transit Mixer, drives directly onto the construction site and mechanically controls the position of its discharge chute. It is ideal for mass concreting and construction projects on narrow sites.
What are the Different Types of Concrete Trucks?
There are various types of concrete trucks available in the market. For example, there are rear discharge trucks and front discharge trucks. Rear discharge trucks have a rear discharge chute that must be operated by a worker at the back. This allows the truck to travel at a faster pace and arrive at the job site with less downtime. Front discharge trucks, on the other hand, allow the driver to place concrete directly from the cab.
Volumetric concrete trucks are among the most advanced models and offer exceptional advantages. These vehicles are equipped with separate compartments for raw materials, which are then metered and mixed only when needed. This eliminates expensive material wastage. Besides that, it keeps operating costs down by mixing only what is needed.
A concrete truck with a pump is called a pump truck. These trucks can pour concrete over a house or into a high-rise building. They also have stand-alone pumps, which can work in tight spaces. The concrete is poured into the pump by the truck.
How Much is a Concrete Mixer Truck?
A concrete mixer truck can save a construction company time and money. These vehicles are larger and more productive than other types of mixers, and can mix up to 3 yards of concrete at a time. Typically, a concrete mixer truck can mix eight cubic meters of concrete at a time, but larger models can mix up to ten cubic meters at a time.
The average cost of a concrete mixer truck is between $55 and $65 per cubic yard. This price includes the cost of delivering a full load. This is equal to the weight of the truck when fully loaded, and translates to approximately 10 cubic yards per truck. Typically, a full load will take approximately seven minutes to mix. However, it’s recommended that you plan your project early in the day to avoid waiting hours and additional charges.
Concrete trucks cost a minimum of $100,000, but some can cost as much as $150,000. It’s important to consider the features you need, how much you want to spend, and the total workload your concrete truck is expected to handle. However, there are cheaper alternatives to concrete trucks, including hand trucks. Although hand trucks are cheaper than concrete trucks, they require special care to perform well.
How Long Does It Take to Empty a Concrete Truck?
The time it takes to empty a concrete truck will vary depending on the quantity and quality of the concrete used. If you order more than five yards, you can expect to wait until afternoon before the truck is emptied. If you’re not sure when the truck will be empty, call ahead.
Most concrete trucks leave job sites with excess cement. Depending on the situation, the driver may clean the truck at the next job site or take it to a dumping site. However, these options can be time consuming and costly. Therefore, the more common option is to take the cement back to the mixing plant. This way, it can be reused on other projects or stored for future use.
Concrete trucks are 20 feet long. Because of their length, they can only reach certain points on the property. This means that the driver needs to take into account the compaction of the soil and the thickness of the concrete slab before it can leave the site.
How Do Concrete Trucks Get Cleaned?
Concrete trucks have a messy and hard to clean interior, but it can be done. Using high-performance concrete-cleaning products, like Mortarman CR-650, makes the job much easier. The best concrete-cleaning products don’t use hydrochloric acid, also known as muriatic acid, which can be harmful to people and the environment.
Typically, concrete trucks are cleaned using a hose and fresh water. It’s important to get any splatter off the truck before putting it back into service. At a concrete plant, however, high-pressure spray nozzles blast the truck with water. This is the equivalent of a massive car wash.
Once the truck leaves the concrete plant, it will begin setting up into a paste. If you’d like to speed up the setting time, add additives. The most common additive is sugar. This sweetener will help the cement set up faster.
