Robotic Hydrodemolition in Ystad, Sweden. Hydrodemolition of concrete exposing the rebar.. Hydrodemolition (also known as hydro demolition, hydroblasting, hydro blasting, hydromilling, waterblasting, and waterjetting) is a concrete removal technique which utilizes high-pressure water, often containing an abrasive material, to remove deteriorated and sound concrete as well as asphalt and grout.
Concrete from a building being sent to a portable crusher. This is the first step in recycling concrete. Crushing concrete from an airfield. Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. [1]
Hydraulic hammers are often used for concrete structures and concrete processing attachments are used to crush concrete to a manageable size, and to remove reinforcing steel. For tall concrete buildings, where neither explosive nor high reach demolition with an excavator is safe or practical, the "inside-out" method is used, whereby remotely ...
Dam Removal Europe helped dismantle 325 dams or other buildings in 2022, a 36% increase over 2021. [ 13 ] [ 14 ] [ 15 ] The WWF, The Rivers Trust , The Nature Conservancy , The European Rivers Network, Rewilding Europe , Wetlands International Europe, and The World Fish Migration Foundation have formed a coalition to restore Europe's rivers and ...
It is common practice, and common sense, to “soft-strip” the structure first; remove all appliances, windows, doors, and other finishing materials. These will account for a large percentage of the marketable components. After the non-structural deconstruction, structural is the next step.
AfE-Turm building demolition slow motion video Implosion of the Athlone Power Station cooling towers Blasting of a highway bridge in Aachen, Germany. In the controlled demolition industry, building implosion is the strategic placing of explosive material and timing of its detonation so that a structure collapses on itself in a matter of seconds, minimizing the physical damage to its immediate ...
Milling can also remove distresses from the surface, providing a better driving experience and/or longer roadway life. Some of the issues that milling can remove include: [2] Raveling: aggregate becoming separated from the binder and loose on the road [3] Bleeding: the binder (asphalt) coming up to the surface of the road [4]
The extrusion nozzle may be accompanied by an automatic troweling tool that flattens the 3D-printed layers and covers the grooves at the interlayer interfaces, resulting in a smooth concrete surface. Additional automation steps have been proposed for the integration in one fabrication step of modular steel reinforcement bars or integrated ...
