A concrete pump works by using a valve system and the basic principles of hydraulics. After a mixing truck pours liquid concrete into a hopper, the concrete pump sucks the liquid concrete through a valve system and into the area where it needs to be laid down. It pulls concrete out of the hopper.
How fast can a concrete pump work?
Ground line hydraulic pumps can shift concrete at 1m³ each minute and can extend to a distance of around 150 meters, in order to reach the pour site. This makes concrete pouring in awkward areas simple, as the pipes and hoses can go up, over and around obstacles.
How far can they pump concrete?
Booms for these trucks can come in configurations of three and four sections, with a low unfolding height of about 16 feet that makes it ideal for placing concrete in confined areas. Longer, five-part booms can reach up or out more than 200 feet.
What kind of pump is commonly used in concrete pumping?
It is known as a boom concrete pump because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately. Boom pumps are used on most of the larger construction projects as they are capable of pumping at very high volumes and because of the labour saving nature of the placing boom.
How much does a concrete pump cost per hour?
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.
Can you pump concrete through a house?
The concrete pump pipeline can easily be passed through the front door and the rest of the house, and out into the garden – with little mess and no fuss. This is the same for other hard-to-reach areas, such as basements and sites with narrow entrances and down alleyways.
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.
Is it OK if it rains after pouring concrete?
Pouring Concrete in Rain. Pouring concrete in the rain can compromise its strength, increasing the tendency for dusting and scaling to develop. Once the damage is done, it can be hard to rectify and will often ruin the appearance of the finished surface. Don’t let it rain on your parade.
How much does it cost to get concrete pumped?
Our rates are as follows: Concrete Pumping Rates Metres pumped $7 per cubic metre pumped + GST Hourly rate $160 per hour (minimum of 4 hours per job site) + GST Travel (one hour) $160 + GST Boom Pumps.
When should you use a concrete pump?
Purpose & Types Of Projects Concrete Pumps Are Used For Small line pumps transport smaller volumes of concrete, so they are ideal for smaller concrete construction projects, such as pools, sidewalks, ground slabs, low-rise construction, and slabs for single-family homes.
How many types of concrete pumps are there?
There are two basic types of concrete pumps i.e., boom pumps and stationary pumps and both of which have their own unique qualities. Even a third variant exists i.e., specialised pumps which are used for specialised jobsites.
Do I need a concrete pump?
1m3 of concrete per minute). You will also need to use a pump if the concrete mixer truck can’t get close enough to the pour area or access to your site is restricted, underground, within an existing building or at height.
What are the advantages of pumping concrete?
10 benefits of concrete pumping: Concrete pumping is a faster and easier method to complete a project. Concrete pumping can reduce labour costs. It reduces site congestion as there are less construction workers. You can get concrete to high rising and far reaching places.
Is Concrete Pumping a good business to start?
The interest in truck-mounted concrete pumps continues to grow amid the push for ever-higher productivity gains on modern construction sites. It means the business of pumping concrete is annually worth an estimated $1.75 billion in the U.S. and it’s expected to be worth $2.3 billion by 2021.
How much is a yard of concrete?
Cost. Use $90 per cubic yard as a ballpark figure for concrete prices, but concrete slab cost will vary by region. Also, expect a fee of about $60 per load for delivery from a concrete truck for concrete cost. There could be other fees for such things as Saturday concrete truck delivery and small loads.
How many yards does a concrete truck hold?
Most concrete trucks can hold between 11 and 15 cubic yards of concrete. However, weight limits on roads often limit the amount they can carry to 8 to 11 cubic yards.
How do you get concrete behind a house?
A line pumps hose will fit through an opening less than a foot wide and pump concrete around your house into the backyard. Or a boom pump can reach over your house and pump concrete into the backyard. Both cost money to hire, but definitely beat pushing wheelbarrows through your house.
What is the cost of concrete?
For concrete, the formula for volume is as follows: length x width x thickness. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield. Use the following yields per each bag size: 40 pound bag yields .011 cubic yards.
What is concrete pump mix?
The ideal concrete mix for pumping typically contains air-entraining agents, a little extra sand (compared with a standard concrete mix), often some fly ash, and a well-graded aggregate blend.
