The rapid development of the economy, more and more infrastructure projects in cities, the market demand for cement is very large, so how should be transported to the site in the cement plant, this time there are a variety of ways, there are bags of cement, bulk cement tankers, concrete mixer trucks, so how should you choose it, I hope this article is helpful to you.
What is Bagged Cement ?
Bagged cement is the cement that is packed in woven bags with bearing cement. Generally, it is packed in paper bags (including peritoneal plastic woven bags, composite bags, etc.) for delivery, transportation, storage and use. Bags are easy to store in, suitable for small sites and small amounts of use.
What is a Bulk Cement Truck ?
Bulk cement truck, bulk cement tanker (bulk cement trailer) alias cement tanker, powder material truck. Vehicles with closed cargo compartments and automatic unloading devices for the transport of bulk cement.
Bulk cement truck means that after the cement is produced from the factory, it does not need any small packaging, but must be transported from the factory to the transfer station or the user through the bulk cement transport vehicle or container.
The use of bulk cement trucks is because of the need for large quantities of hundreds of thousands of tons of cement, large construction factories, cement factories, construction sites, oil
What is a Concrete Truck ?
Concrete mixer truck (cement mixer, concrete mixer) is a special truck used to transport concrete for construction; because of its shape, it is also often called a snail truck. These trucks are equipped with cylindrical mixing drums to carry the mixed concrete. During transportation, the mixing drum is kept rotating to ensure that the concrete carried does not solidify. After the concrete has been delivered, the inside of the mixing drum is usually flushed with water to prevent the hardened concrete from taking up space.
Price Difference
- Bagged cement is more expensive per ton than bulk cement
- The production cost of bulk cement is lower than that of bagged cement. For the same grade of cement, the cost of bulk cement can be reduced by about 20% than that of bagged cement.
Storage Time
- Storage time of bagged cement is 3 months
- Bulk cement trucks seldom deteriorate after being stored for one year. From the factory to use, although the circulation has been transported many times, the cement is always stored in a closed container, which is not easily affected by wind and sun.
- The strength of bulk cement is slightly higher than that of bagged cement under the same grade
The medium of storage
A cement bulk truck is a truck that is handling and transporting bags of cement on a large scale in a loose manner only (not in bags).
Concrete trucks are ready mixed trucks for ready mixed concrete. You may find ready mixes of cement, gravel, sand and water on the road for use in ready-made slabs, walls, columns or beams ETC.
Cement VS Concrete
Differences in form.
Concrete is generally in liquid form, while cement is generally in powder form.
Different composition.
The main ingredients of concrete are cement, sand, water, stone etc
The main ingredients of cement are limestone, clay, iron minerals, etc.
Different material properties.
Concrete is a substance that is made using a mixture of cement, sand, stone, water, etc.
Cement is a bonding material and is an auxiliary material required for the construction of building renovations.
Differences in hardness.
Concrete is harder, cement is less hard.
Abrasion resistance differs.
Concrete is more resistant to wear and is very durable
Cement is less abrasion resistant than concrete and can be easily worn.
Differences in scope of application.
Concrete is generally used for insulation, waterproofing, etc.
Cement is generally used for civil construction, industrial construction, etc.
Bulk Cement Truck vs Concrete Mixer Working Principle
Bulk Cement Truck Working Principle
Using the power of the vehicle to drive the air pressure compressor to send compressed air through the pipe into the air chamber under the sealed tank to make the material body in the fluidized bed of the air chamber suspended into a fluid state. When the pressure inside the tank reaches the rated value, the discharge valve is opened and the fluidised material is conveyed through the pipe flow.

Concrete Mixer Working Principle
The drum mixer is mounted on a truck chassis. The mixer is either driven by the truck engine or by a separate slave engine. The drum has a spiral blade inside it, such as an Archimedes spiral. When the drum is rotated in one direction, for example clockwise (which may vary from manufacturer to manufacturer), the concrete in the drum is pushed towards the bottom of the drum.
The mixer therefore rotates clockwise and keeps the concrete inside as it is delivered to the construction site (this mixing is needed to prevent premature setting of the concrete).
On arrival at the site, the rotation of the drum will be reversed counter-clockwise in order to pour the concrete. The blade now pushes the concrete into the opening of the drum and thus pours it to the outside. Please see the animation below.
Performance Characteristics
Features of Bagged Cement:
- High energy consumption. For every 10,000 tons of bagged cement, 330m3 of wood, 22 tons of caustic soda, 78 tons of coal, 12,000m3 of water, and 72,000 kWh of electricity are consumed.
- Big dust. The damage rate of bagged cement in construction projects is 5%, and the cement in the dust particles accounts for 10%-20%.
- The loading and unloading is slow, the intensity is high, and the working conditions are poor.
- Costly. For every 10,000 tons of bagged cement, the comprehensive cost of paper bags (or plastic woven bags, etc.), handling, unpacking, and damage is more than 640,000 yuan.
- If the bagged cement is stored for half a year, the strength will be reduced by 20-30%, so it cannot be transported around the clock and operated in the open air.
Features of Bulk Cement Transporter
- Save a lot of energy and resources. Save a lot of wood, protect forest resources and protect the ecological environment;
- Promote and improve the quality of cement products, commercial concrete quality and engineering quality;
- It is the only way to realize the modernization of building materials industry, storage and transportation industry and construction industry;
- It is one of the important contents to improve the overall quality of the national economy;
- Greatly improve the working environment and protect the health of working people;
- Reduce cement dust pollution during construction and protect the environment.
Advantages of concrete mixer truck
- The production process strictly implements national and industry standards to ensure the quality of commercial concrete;
- Admixtures and admixtures can be added as needed to flexibly adjust the initial setting time and slump of commercial concrete to ensure the production of high-grade commercial concrete, thereby avoiding “fat beams, fat columns, and thick slabs” in construction projects and expanding buildings. effective space;
- Can provide a large amount of commercial concrete at any time to ensure the construction site’s requirements for the progress of the construction period;
- Pumping construction can carry out high-rise and certain distance operations, improve efficiency, and make it possible to carry out continuous and seamless construction of large-volume commercial concrete;
- Fully enclosed production, avoid noise and dust pollution to the urban environment, and also avoid the blockage of the sewers caused by on-site mixing of commercial concrete such as sand and stone, which has good environmental protection benefits;
- Reduce the area where materials are stacked on the construction site, avoid traffic jams, and avoid the status quo of “building a building and damaging a road”, keeping the construction environment clean, and making it possible to achieve civilized construction;
- It is conducive to promoting the development of commercial concrete in the direction of high strength, special effects, high performance and durability.
- Conducive to the further development of bulk cement business.
4 Advantages of Bulk Cement Tanker Truck
The bulk cement truck is used to collect and transport cement powder or other kinds of powder, such as coal powder, mineral stone powder.
- Reduce human resource consumption and improve labor efficiency;
- Save packaging bag material costs and reduce costs;
- There is no damage to the packaging bags during the transportation of cement tankers, so the loss rate of canned cement is lower than that of bagged cement;
- The bulk cement tanker is not easy to be affected by moisture during transportation, and it is rarely deteriorated after one year of storage, which is conducive to improving the construction efficiency and engineering quality
Disadvantages of bulk cement truck
The cost of the whole vehicle is high, and bulk cement tanker is suitable for large-volume cement transportation.
