In masonry, it refers to shaping a stone to a rough square by use of an axe or hammer. [1] In Kent, rag-stone masons call this "knobbling". [1] It was similarly used to shape grindstones. In modern construction, scabbling is a mechanical process of removing a thin layer of concrete from a structure, typically achieved by compressed air powered ...
Reinforced earth with gabions supporting a multilane roadway Gabions as X-ray protection during customs inspection. A gabion (from Italian gabbione meaning "big cage"; from Italian gabbia and Latin cavea meaning "cage") is a cage, cylinder or box filled with rocks, concrete, or sometimes sand and soil for use in civil engineering, road building, military applications and landscaping.
A keystone (or capstone) is the wedge-shaped stone at the apex of a masonry arch or typically round-shaped one at the apex of a vault. In both cases it is the final piece placed during construction and locks all the stones into position, allowing the arch or vault to bear weight.
The Greeks called the construction technique emplekton [4] [5] and made particular use of it in the construction of the defensive walls of their poleis. The Romans made extensive use of rubble masonry, calling it opus caementicium , because caementicium was the name given to the filling between the two revetments .
Staff is a kind of artificial stone used for covering and ornamenting temporary buildings. Facade of the Fisheries Building, World's Columbian Exposition . Three pillared archways are constructed and finished, in front of a bare wall of wooden studding that has not yet been rendered.
Galleting is mainly used in stone masonry buildings constructed out of sandstone or flint. The technique varies depending on which of these materials is used. In sandstone buildings, the spalls are often a different type of sandstone than the one used in the wall, though sometimes they are pieces of the same stone.
Asphalt and sandbag revetment with a geotextile filter. A revetment in stream restoration, river engineering or coastal engineering is a facing of impact-resistant material (such as stone, concrete, sandbags, or wooden piles) applied to a bank or wall in order to absorb the energy of incoming water and protect it from erosion.
construction site workers loading water, sand, ballast and cement into a concrete mixer. Concrete is typically used in commercial buildings and civil engineering projects, for its strength and durability. Concrete is a mix of cement and water plus an aggregate such as sand or stone. Its compression strength means it can support heavy weights. [5]
