What kind of pump is commonly used in concrete pumping?
A boom or truck mounted concrete pump is best suitable for the construction of huge road and highway projects. For concrete pouring at several altitudes, where there is a limited area for the concrete pouring, a boom concrete pump is the best choice.
What distance Can concrete be pumped?
How far can you pump concrete? A line pump can cover distances of around 150 metres while boom pumps can reach approximately half this distance.
How does a pump truck work?
Modern concrete pumps trucks have twin cylinder hydraulic systems with one piston drawing up liquid concrete into a cylinder from the hopper while the other pumps concrete out into discharge pipes. The system is controlled by valves so as the first cylinder discharges the other draws up fresh concrete from the hopper.
What are the major problems in using pumping for concreting works?
Major Problems in Concrete Pumping Works
- Blockage of Concrete Pump.
- Segregation and Bleeding in Concrete Mix.
- Concrete Mixture.
- Handling Concrete.
- Selection of Pumping Equipment.
- Use of Poor-Quality Materials.
- Selection of Improper Additives for Concrete.
- Failure to Maintain Pump Pipeline.
Do I need a concrete pump?
The main purpose of concrete pumps is to save time, money, and energy during a concrete project, large or small. Instead of hauling concrete to the desired location, a pump allows you to place concrete precisely where you need it, no matter the obstacles that are in the way of reaching the area with a truck.
How much does it cost to pump concrete?
Concrete pumps are rented by the hour. Generally speaking, hourly rates will range somewhere between $150 and $200. Prices will vary based on region and the amount of competition in the area. Most rental companies will require a minimum rental time.
Is pumped concrete weaker?
It was believed for many years that a pump mix was weaker because it had to be batched with less large aggregate and more sand. We have learned over the years that a pump mix will be a better product because it will have a better gradation and maybe even a little more cement and the mixing will be better.
How long are concrete pumps?
A ground line pump can reach over 150 meters, with possible extensions if required. A boom pump can extend up to 72 meters. with possible extensions if required.
What is pump mix concrete?
Pumped concrete may be defined as concrete that is conveyed under pressure through either rigid pipe or flexible hose and discharged directly into the desired location. Pumping may be used for most all concrete construction, but is especially useful where space or access for construction equipment is limited.
What is Pumpcrete?
The line pump uses flexible or steel hoses attached to the outlet of the pump and linked together to wherever the concrete needs to go. This type of pump is usually used for smaller jobs like swimming pools, ground slabs and sidewalks.
Is mixing your own concrete cheaper?
One of the least expensive ways to get concrete is to mix your own. You can buy bags of the mix from a home improvement store. Typically, you only have to add water for it to be ready to pour. Otherwise, you risk getting a weaker concrete once it cures, which could lead to cracks or crumbles within a couple of years.
Why should pumping be not used in case of concreting works?
During the pumping operation the pump exerted pressure must overcome any friction between the pumping pipes and the concrete, also the weight of the concrete and the pressure head when the concrete is placed above the pumps. The major problem due to pumping are segregation effects and bleeding.
