High-pressure chemistry is concerned with those chemical processes that are carried out under high pressure – pressures in the thousands of bars (100 kPa) or higher.High-pressure processes are generally faster and have a higher conversion efficiency than processes at ambient pressure.
Putzmeister was founded by Karl Schlecht in 1958. [3] Schlecht designed a mortar machine based on his diploma thesis at the University of Stuttgart. [4]In 1986, Putzmeister 52Z's were used in the Chernobyl nuclear accident, pumping over 300,000 m 3 (390,000 cu yd) of concrete to entomb reactor number 4, setting a world record at the time for volume pumping.
The THTR-300 was a helium-cooled high-temperature reactor with a pebble bed core consisting of approximately 670,000 spherical fuel compacts each 6 centimetres (2.4 in) in diameter with particles of uranium-235 and thorium-232 fuel embedded in a graphite matrix. The pressure vessel that contained the pebbles was prestressed concrete.
The chemical industry in Germany is one of the most well-established in the world, and a world leader; a quarter of the chemicals made in the EU, are made in Germany. Currently the German industry, turning over 160 billion euros [ 1 ] is the European leader, and the third-biggest in the world.

A pressure washer is used to remove old paint from a boat. Patio flagstones being pressure washed using a rotary nozzle. Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces.
The Leuna works (German: Leunawerke) in Leuna, Saxony-Anhalt, is one of the biggest chemical industrial complexes in Germany. [1] [2] The site, now owned jointly by companies such as TotalEnergies, BASF, Linde plc, and DOMO Group, covers 13 km 2 and produces a very wide range of chemicals and plastics.

Robotic Hydrodemolition in Folkestone, UK. 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.
