Context: Stucco or render is a material made of aggregates, a binder, and water. Stucco is applied wet and hardens to a very dense solid. It is used as decorative coating for walls and ceilings and as a sculptural and artistic material in architecture. Stucco may be used to cover less visually appealing construction materials such as metal, concrete, cinder block, or clay brick and adobe., Road surface or pavement is the durable surface material laid down on an area intended to sustain vehicular or foot traffic, such as a road or walkway. In the past, gravel road surfaces, cobblestone and granite setts were extensively used, but these surfaces have mostly been replaced by asphalt or concrete laid on a compacted base course. Road surfaces are frequently marked to guide traffic. Today, permeable paving methods are beginning to be used for low-impact roadways and walkways., In geometry, an octagon (from the Greek  "oktágnon", "eight angles") is an eight-sided polygon or 8-gon., A cement is a binder, a substance used in construction that sets and hardens and can bind other materials together. The most important types of cement are used as a component in the production of mortar in masonry, and of concrete, which is a combination of cement and an aggregate to form a strong building material., A chamfer is a transitional edge between two faces of an object. It can also be known as a bevel but connotes more often cutting and is more often 45° with respect to the two adjoining faces. If the un-chamfered intersection of the adjoining faces would otherwise form a right angle, 90° as is most common, the chamfer will typically be uniform and pitched at 45° . A fully chamfered square interior would thus be octagonal. (By contrast, a fillet is the rounding-off of an interior corner, and a rounding of an exterior corner is called a "round" or a "radius"), A bevelled edge (UK) or beveled edge (US) refers to an edge of a structure that is not perpendicular to the faces of the piece. The words bevel and chamfer overlap in usage; in general usage they are often interchanged, while in technical usage they may sometimes be differentiated as shown in the image at right. A bevel is typically used to soften the edge of a piece for the sake of safety, wear resistance, or aesthetics; or to facilitate mating with another piece., Screed has three meanings in building construction. 1) a flat board (screed board, floating screed) or a purpose-made aluminium tool used to smooth and true materials like concrete, stucco and plaster after it has been placed on a surface or to assist in flattening; 2) a strip of plaster or wood applied to a surface to act as a guide for a screed tool (screed rail, screed strip, screed batten); 3) the material itself which has been flattened with a screed (screed coat). In the UK, "screed" has also come to describe a thin, top layer of material (traditionally sand and cement), poured in site on top of the structural concrete or insulation, on top of which other finishing materials can be applied, or it can be left bare to achieve a raw effect. It is becoming more common to use "self-leveling" poured screeds which use materials other than cement as their binder., Aluminium or aluminum (in North American English) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile metal. Aluminium is the third most abundant element in the Earth's crust (after oxygen and silicon) and its most abundant metal. Aluminium makes up about 8% of the crust by mass, though it is less common in the mantle below. Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals. The chief ore of aluminium is bauxite., Batten has multiple meanings in construction and shipbuilding but is generally a strip of solid material, historically made from wood but can also be made from plastic, metal, or fiberglass. In a sense used in flooring a batten may be relatively large, up to thick by wide and more than long., Portland cement is the most common type of cement in general use around the world, used as a basic ingredient of concrete, mortar, stucco, and most non-speciality grout. It was developed from other types of hydraulic lime in England in the mid 19th century and usually originates from limestone. It is a fine powder produced by heating materials in a kiln to form what is called clinker, grinding the clinker, and adding small amounts of other materials. Several types of Portland cement are available, with the most common being called ordinary Portland cement (OPC) which is grey in color, but a white Portland cement is also available., Asphalt (, occasionally ), also known as bitumen is a sticky, black and highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product; it is a substance classed as a pitch. Until the 20th century, the term asphaltum was also used. The word is derived from the Ancient Greek  "ásphaltos"., A craft is a pastime or a profession that requires particular skills and knowledge of skilled work. In a historical sense, particularly as pertinent to the Middle Ages and earlier, the term is usually applied to people occupied in small-scale production of goods, or their maintenance, for example by tinkers. The traditional terms "craftsman" and "craftswoman" are nowadays often replaced by "artisan" and rarely by "craftsperson" (craftspeople)., A concrete finisher , is a tradesman who works with concrete . The job entails placing , finishing , protecting and repairing concrete in engineering and construction projects . Concrete finishers are often responsible for setting the concrete forms , ensuring they have the correct depth and pitch . Concrete finishers place the concrete either directly from the concrete wagon chute , concrete pump , concrete skip or wheelbarrow . They spread the concrete using shovels and rakes , sometimes using a straightedge back and forth across the top of the forms to `` screed , '' or level , the freshly placed concrete . After levelling the concrete , they smooth the surface using either a hand trowel ) , a long handed `` bull float '' or powered floats . After the concrete has been leveled and floated , concrete finishers press an edger between the forms and the concrete to chamfer the edges so that they are less likely to chip . Broom and stamp finishes are a couple of different finished products for outdoor concrete after the trowel - finish is complete . The broom finish is used to prevent slipping on the concrete , and the stamp finish is used for looks ., Concrete is a composite material composed of coarse aggregate bonded together with a fluid cement that hardens over time. Most concretes used are lime-based concretes such as Portland cement concrete or concretes made with other hydraulic cements, such as ciment fondu. However, asphalt concrete, which is frequently used for road surfaces, is also a type of concrete, where the cement material is bitumen, and polymer concretes are sometimes used where the cementing material is a polymer., A composite material (also called a composition material or shortened to composite, which is the common name) is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons: common examples include materials which are stronger, lighter, or less expensive when compared to traditional materials. More recently, researchers have also begun to actively include sensing, actuation, computation and communication into composites, which are known as Robotic Materials., A tradesman, tradesperson or skilled tradesman refers to a worker that specializes in a particular trade or craft requiring skill . , Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac or bitumen macadam in Great Britain and Ireland) is a composite material commonly used to surface roads, parking lots, and airports. It consists of mineral aggregate bound together with asphalt, laid in layers, and compacted. The process was refined and enhanced by Belgian inventor and U.S. immigrant Edward de Smedt. It is increasingly being used as the core of embankment dams., Polymer concretes are a type of concrete that use polymers to replace lime-type cements as a binder. In some cases the polymer is used in addition to portland cement to form Polymer Cement Concrete (PCC) or Polymer Modified Concrete (PMC). Polymers in concrete have been overseen by Committee 548 of the American Concrete Institute since 1971., Subject: concrete finisher, Relation: instance_of, Options: (A) angle (B) architecture (C) area (D) asphalt (E) binder (F) chemical (G) chemical element (H) combination (I) committee (J) common name (K) communication (L) component (M) composite material (N) concrete (O) construction (P) craft (Q) eight (R) england (S) fluid (T) group (U) ingredient (V) liquid (W) masonry (X) mass (Y) material (Z) may ([) metal (\) mineral (]) mortar (^) object (_) pavement (`) polygon (a) polymer (b) production (c) profession (d) road (e) sense (f) shipbuilding (g) skill (h) structure (i) symbol (j) three (k) time (l) tool (m) trade (n) two (o) water (p) will
