If you are new to the the world of hydrodemolition the terminology can sometimes be difficult. This is a list of specific terms being used in the concrete removal and hydrodemolition field.
A metric unit of pressure. 1 Bar = 14.5 psi
1 = atmospheric pressure at an altitude of 111 meters above sea level at 15 deg. C.
When new concrete is put on top of old concrete, to restore a structure.
The ability of concrete to withstand forces that are pushing on it without braking.
The assembly that the cutting lance is attached to and allows the robot to aim and manipulate the water jet.
The assemble including the nozzle that is the robots final contact with the water.
The structure of the robot that the cradle travel on. It can be straight or curved to match a surface profile.
The process of selective removal of concrete by means of one or more high-speed water jets.
A crack in the structure that appears when concrete is removed using methods creating friction in the structures, which in turn creates micro cracks.
Multipurpose arm. This is one of Conjets unique features and it allows you to easily adjust and position the cutting head from the remote control.
The smallest ACR™ robot on the market, allowing allows selective concrete removal in inaccessible areas.
The capacity to remove concrete to a specific depth, not based on the concrete strength.
A unit for measuring pressure or stress
1 MPa = 145.038 psi
PSI (POUNDS PER SQUARE INCH)
A unit for measuring pressure or stress.
14.7 psi = atmospheric pressure sea level
The capacity to remove concrete by its strength and not to a specified depth.
The distance the track(s) will move during operation.
Determines the length of time the valve for track movement is open during operation.
Different constructions build of concrete: bridges, dams, docks, parking decks, tunnels etc.
The ability of the concrete to withstand pulling forces without breaking.
