Concrete pumps are machines used to transport the freshly mixed concrete mass to the place of pouring. Before concrete pumps were invented, the concreting of tall structures was done by placing the concrete on hoppers and carrying them using cranes.
Shotcrete is more economical than conventional concrete because it requires less formwork. It only requires a small space for construction and its location. In the case of the shotcrete, cement content is high, so it is durable. It is resistant to fire, disasters, mold, worms and also has low permeability. It also has a good thermal resistance
Industrial applications of mounted concrete pumps include construction of dams, high rise buildings, industries, factories, bridges, canals and many such construction projects. Shotcrete Machine Shotcrete is an alternative and increasingly used equipment for placing concrete.

Shotcreting has become an increasingly popular form of concrete placement given a large demand for unconventional and complex designs amongst construction, infrastructure and development projects. Shotcreting refers to a process which utilises compressed air to disperse concrete at high velocities onto structural surfaces, being commonly referred to as 'Concrete Spray' or 'Spraycrete'.
Benefits of Using Concrete Pump in Construction Project. It is a common sight to see concrete pumps being used in a large-scale commercial construction project. However, these cutting-edge concrete pumping machines are equally effective and economical for small to medium sized construction projects, regardless if it a commercial or residential
27/4/2020 · Shotcrete – sprayed concrete – has become a common practice for both new construction and repair and renovation. Concrete can be sprayed by one of two processes – one is "dry shotcrete" or "gunite" in which case dry material floats to the end of the …
2/5/2013 · Your specific questions concern OSHA enforcement policy for construction concrete pumping operations using over-the-road, truck-mounted concrete boom pumps ("concrete boom pump trucks").

28/11/2012 · What Is Concrete Pumping?Concrete pumping is a more efficient way of pouringconcrete, using a machine to transfer liquid concrete.There are two basic types of pumps that are used, one isknown as a 'boom pump' and the other is commonly calleda 'line 5.
Because concrete repair tends to require units with lower volume capaci-ties, most of the pumps listed have rated outputs of less than 40 cubic yards per hour. However, contractors must determine a pump's true output volume before using it for shotcreting. For
7/8/2013 · Another trend making waves in the industry today is shotcrete pumps with built-in accelerator pumps. It has always been common for admixtures to be used in shotcrete on the East Coast and regular concrete only on the West Coast. But today, more contractors on the West Coast are beginning to use …
All concrete pumps are not created equal! But they play a very important – you might say "integral" – part in Monolithic Dome construction. Consequently, in this section we include articles that present a very brief history of concrete pumps, the advantages and disadvantages of peristaltic pumps and hoses, and what Monolithic recommends based on years of experience in using concrete pumps.
What Concrete Pumps do, how they work, different types of concrete pump and the advantages of Schwing concrete pumps. Schwing Stationary Trailer Mounted Concrete Pumps These machines range from the SP305, ideal for all foundations and residential slabs through to the SP8800 which pumps the concrete to the top of the tallest structures in the world.
Concrete Pump: Types, Advantages & Disadvantages
15/2/2001 · These pumps typically are equipped with swing-tube valves, 6-inch-diameter pump cylinders, and 5-inch-diameter outlets and have outputs up to 40+ cubic yards per hour for conventional pumping. When the pumps are used for wet shotcreting with a 2-inch-diameter hose, line reducers at the pump outlet cut the output to about 20 cubic yards per

1/11/1995 · In wet shotcreting, a concrete pump delivers ready mixed concrete with a predetermined water-cement ratio to the shooting nozzle at a rate of approximately 3 feet per second. Compressed air traveling at 150 to 200 feet per second is then introduced at the nozzle, a precise dose of fluid accelerator is usually injected into the propellant air.
