Context: 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., Frontage is the boundary between a plot of land or a building and the road onto which the plot or building fronts. Frontage may also refer to the full length of this boundary. This length is considered especially important for certain types of commercial and retail real estate, in applying zoning bylaws and property tax. In the case of contiguous buildings individual frontages are usually measured to the middle of any party wall. , A building or edifice is a structure with a roof and walls standing more or less permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, to land prices, ground conditions, specific uses and aesthetic reasons. To better understand the term "building" compare the list of nonbuilding structures., Masonry is the building of structures from individual units, which are often laid in and bound together by mortar; the term "masonry" can also refer to the units themselves. The common materials of masonry construction are brick, building stone such as marble, granite, travertine, and limestone, cast stone, concrete block, glass block, and cob. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can significantly affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer., A façade is generally one exterior side of a building, usually, but not always, the front. It is a foreign loan word from the French façade, which means "frontage" or "face"., Fibre cement is a composite building and construction material , used mainly in roofing and facade products because of its strength and durability ., The face is a central organ of sense and is also very central in the expression of emotion among humans and among numerous other species. The face is normally found on the anterior ("frontal", "rostral") surface of the head of animals or humans, although not all animals have faces. The face is crucial for human identity, and damage such as scarring or developmental deformities have effects stretching beyond those of solely physical inconvenience., 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., Subject: fibre cement, Relation: subclass_of, Options: (A) bitumen (B) boundary (C) brick (D) building (E) building stone (F) cement (G) composite material (H) concrete (I) construction (J) damage (K) edifice (L) emotion (M) estate (N) factory (O) granite (P) house (Q) length (R) limestone (S) marble (T) masonry (U) material (V) mortar (W) organ (X) pattern (Y) person (Z) plot ([) polymer (\) real estate (]) road (^) sense (_) standing (`) stone (a) surface (b) tax (c) term (d) word (e) zoning
