Concrete chipping is a process which requires trained chippers or a robotically-controlled machine with an ultra high pressure water source (20,000 psi) to enter the drums of ready-mix concrete trucks and central mixers to break away the dried concrete along the drums’ walls.
Scabbling is used to remove road markings, surface contamination (used in the nuclear industry), to add a decorative or textured pattern to concrete, or to prepare a concrete surface prior to the installation of grout. [2] Scarifying machines with flails attached to a drum cage are sometimes referred to as rotary scabblers.
In 1976, the site was purchased by Cooper Drum Company. [1] Cooper Drum Company’s main recycling operation was reconditioning steel drums. Initially the drum reconditioning was conducted along the southern portion of the property. This was an assembly line process along an elevated concrete floor. Drums were flushed and stripped with sodium ...
A reversing drum mixer (also commonly called a non-tilting mixer) is a type of concrete mixer that produces concrete in single batches. The entire drum rotates around its axis as materials are loaded through a charge chute at one end of the drum and exit through a discharge chute at the opposite end of the drum.
Concrete has a limited lifespan between batching / mixing and curing. This means that ready-mixed concrete should be placed within 30 to 45 minutes of the batching process to hold slump and mix design specifications in the US, [15] though in the UK, environmental and material factors, plus in-transit mixing, allow for up two hours to elapse.

General Motors is adding over 132,000 heavy-duty pickups in the U.S. to a previous recall for tailgate release switches that can short circuit and open the gates while the trucks are in park. The ...
The one-story, nearly-8,000-square-foot fortification is bulwarked by concrete walls 30 inches thick. The two exterior entrances have armored steel blast doors — one paired with a radiation ...
This is the direction the drum is rotated while the concrete is being transported to the building site. This is known as "charging" the mixer. When the drum rotates in the other direction, the Archimedes' screw-type arrangement "discharges", or forces the concrete out of the drum. From there it may go onto chutes to guide the viscous concrete ...
