Readers ask: How Concrete Pump Works?

How does concrete pumping work?

The Science Behind Concrete Pumping

It works using a valve system and the basic principles of hydraulics. When concrete is required, a mixing truck first mixes concrete within its rotating drum. Then the truck pours its liquid concrete into a hopper, which continues to churn the concrete so it will not solidify.

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.

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 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 the minimum slump for concrete?

Very dry mixes having slump 0 – 25 mm are typically used in constructing pavements or roads, low workability mixes having slump 10 – 40 mm are typically used for foundations with light reinforcement, medium workability mixes with slump 50 – 90 mm, are typically used for normal reinforced concrete placed with vibration,

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 much is a concrete line pump?

Entry–level pumps cost about $19,000, with prices increasing up to about $60,000 for higher–volume pumps with greater pressure. One worker can operate these pumps, which typically include a remote control for regulating the concrete delivery.

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.
