This glossary is now available for download by clicking here: A Glossary of Concrete Pumping Terms agitator A remixer in the hopper that keeps the concrete in a homogeneous state and feeds it towards the pumping cylinders.

Note: the ball catcher should be fitted to steel pipeline — all hoses must be removed before attaching the ball catcher. Bends are available in a number of different radii typically up to 1 metre. Different angle bends are used, the most common of which are 90 and 45 degrees. The common causes of a blockage are 1. The adapter should also include a stop to prevent the sponge ball being forced back under pressure and thus sealing the vent port. Also known as a wash out adapter.

No ground line is used. A boom should be tested and confirmed as sound on an annual basis. A boom pump consists of three major components — 1. Cam-mats Oversized outrigger support pads supplied by Camfaud. Camfaud Camfaud Concrete Pumps Ltd — the leading concrete pump hire company in England supplying boom pumps, static pumps, stationary placing booms, grout mixer pumps, flowing floor screed pumps, pipelines and concrete pumping accessories.

Other materials may be added to the mix to alter its properties. Concrete is a plastic material in its fresh wet state and hardens over time due to a chemical reaction between the cement and water. The length of a standard pipe is 3 metres. Other sizes can be made but are not generally shorter than mm or longer than 6 metres.

They have a flange at both ends to allow them to be coupled together using coupling sets. Concrete pumps can be categorised as static pumps or mobile pumps. Pump primers are often used instead of the more traditional cement grout — they are promoted as being better from a health and safety perspective as they are lighter and less dusty.

Best practice suggests that the pump primer should be pumped to a suitable waste receptacle and not into the structure. CPCS Competent Operator Blue Card The industry standard qualification that demonstrates that an operator is competent to operate a given piece of construction plant.

EASy mode The Schwing system for restricting the slew of the boom that allows the pump to be short-rigged safely and thus fit into a smaller space.

Electric pumps are preferred in tunnels as they do not emit fumes. Both steel and polypropylene fibres can be used. There are two types of gate valves — manual and hydraulic. The best gate valves have a sealing arrangement to prevent grout loss from the valve. A mix of cement and water pumped ahead of the concrete to line the pipeline. This grout lining forms a lubricating layer ahead of the first load of concrete ensuring that the concrete does not block in the line.

Best practice suggests that the grout should be pumped to a suitable waste receptacle and not into the structure. A cementitious material used in the construction industry. Grout pumps cannot be used to pump concrete containing 10 or 20 mm aggregate. It is used for radiation shielding structures and contracts where an increased mass is required. The most common lightweight aggregate used is Lytag and so is often called Lytag concrete or simply Lytag.

It is possible to pump lightweight concrete but attention has to be paid the the consistency of the mix as the aggregates absorbs water under pressure so the mix has a tendency to stiffen when being pumped. A linesman might be expected to help build the pipeline, strip it back during the pour and strip it out and clean it at the end of the day. It is made from fly ash, a waste product created at coal-fired power stations. The vast majority of mobile pumps are equipped with a placing boom to distribute and place the concrete.

Mobile pumps without booms are called line pumps. OSS The Putzmeister system for restricting the slew of the boom that allows the pump to be short-rigged safely and thus fit into a smaller space. Each pump comes equipped with outrigger pads but, if the ground is poor, oversized pads may need to be deployed.

This usually means being fully extended but some pumps, those fitted with a boom interlock that limits the slew of the boom, can work the boom on one side of the pump and short rig on the other side. The concrete is placed via ground line. The ground line may be connected to the pump at the hopper outlet or may be connected at the end of the boom. It generally has more cementitious material and more fines than a standard mix.

Putzmeister A major concrete pump manufacturer, based in Germany but now Chinese owned. The most common reducer is a reducer that allows a reduction from mm to mm pipeline.

Modern pumps are fitted with radio remote controls and a cable remote control for occasions when the radio remote control cannot be used. Schwing A major concrete pump manufacturer, based in Germany but now Chinese owned. There are two main types of screed pumps — a pneumatic conveyor for semi-dry, sand and cement screed and a worm and stator pump used to pump flowing floor screed. It is important to use a seal in at every joint to prevent grout leaking at the joint.

Shotcrete is less popular now due to the dust particles that are released into the atmosphere that could cause a health hazard to the nozzleman. Mostly used to isolate the pump when washing out the pipeline. Sponge balls come in a variety of sizes and density of material soft, medium and hard. The sponge ball selected will be slightly oversized to scour the pipeline clean.

It is a technique widely used to form irregular or curved shapes for example in tunnels, skateparks etc. Static pumps are used on medium to long term contracts; they are set up in a pumping station and left in position the duration of the concreting programme.

Static pumps do not have booms but the pipeline from them can be connected to manual booms or stationary placing booms. They are usually mounted on a steel column and can be free standing or climbed through a building as it progresses. Stationary placing booms are popular on inner city sites where space and crane hook time is at a premium. Steel fibres come in various lengths and weights and can be onerous to pump especially in high doses. They increase the wear on the pump and as such often attract a surcharge from pump hire companies.

Note that only the very smallest, lightest trailer pumps have trailers suitable to allow the pump to be towed to and from site.

Also known as a blow out adapter. It is typically 4 pieces of scaffold board approx 2m long, placed on their ends and nailed together then lined with polythene sheeting.

HG Hydraulic Generators produce high quality electricity from 3,5 kVA up to kVA for 50 or 60 Hz frequencies to power any electric appliance in mobile use. It can be fitted into any mobile hydraulic system and thanks to its compact size and light weight, it is easy to install anywhere on the mobile machine. The HG is turned on by opening the hydraulic oil flow to it. The motor is integrated into the generator and when it starts the generator produces electricity immediately. HG is designed to handle fluctuating hydraulic oil flows to ensure continuous high quality electricity. By installing HG Hydraulic Generator into a mobile machine it increases the vehicles productivity and net worth.

A simple method of concrete mix design for pumpable concrete based on an estimated weight of the concrete per unit volume is described in the paper. The tables and figures presented are worked out by the author from a wide range of Indian materials. The method is suitable for normal weight concrete with admixture. Pumping may be used for most all concrete construction, but is especially useful where space or access for construction equipment is limited. A pumpable concrete, like conventional concrete mixes, requires good quality control, i. Depending on the equipment, pumping rates will vary from 8 to 70 m3 of concrete per hour. Effective pumping range will vary from to meters horizontally, or to meters vertically. Cases have been documented in which concrete has been successfully pumped horizontally meters and beyond meters vertically upward. If pressure is applied via the aggregate it is highly likely that the aggregate particles will compact together and against the inside of the pipe to form a blockage; the force required to move concrete under these conditions is several hundred times that required for a lubricated mix. If, however, pressure is to be applied via the water, then it is important that the water is not blown through the solid constituents of the mix; experience shows that water is relatively easily pushed through particles larger than about microns in diameter and is substantially held by particles smaller than this.
