In surface metrology, surface roughness is a component of surface finish (surface texture). It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth.
Closeup of scabbled concrete during the process of preparing a foundation for grouting under a new equipment skid. Scabbling—also called scappling—is the process of reducing stone or concrete. 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]
Diamond grinding is a pavement preservation technique that corrects a variety of surface imperfections on both concrete and asphalt concrete pavements. Most often utilized on concrete pavement, diamond grinding is typically performed in conjunction with other concrete pavement preservation (CPP) techniques such as road slab stabilization, full- and partial-depth repair, dowel bar retrofit ...
Roughcast or pebbledash is a durable coarse plaster surface used on outside walls that consists of lime and sometimes cement mixed with sand, small gravel and often pebbles or shells. [1] The materials are mixed into a slurry and are then thrown at the working surface with a trowel or scoop.
Surface processing techniques (e.g., washed concrete surfaces, photo concrete, acidified surfaces) can also be used to create the aesthetic of béton brut. Particularly high-quality poured concrete, achieved by leaving enough room between the formwork and the reinforcing bars for the concrete to flow freely, is called Sichtbeton in German and ...
In civil engineering, concrete leveling is a procedure that attempts to correct an uneven concrete surface by altering the foundation that the surface sits upon. It is a cheaper alternative to having replacement concrete poured and is commonly performed at small businesses and private homes as well as at factories, warehouses, airports and on roads, highways and other infrastructure.
The repeated impact of these points into stone or concrete creates a rough, pockmarked texture that resembles naturally weathered rock. They can help to increase bonding effectiveness when applying new concrete to an existing concrete surface by increasing the surface area of the bonding zone. [2]
Rusticated concrete block involves a rough surface with a carved bevel detail around the edge of the face of the block. [2] The rough texture of the face is created by running the concrete across a cast-iron face plate or by using a plaster mold taken from a cut stone block. [3]
