Masonry Dams
Masonry is the craft of building a structure with brick, stone, or similar material, including mortar plastering which are often laid in, bound, and pasted together by mortar. The term ''masonry'' can also refer to the building units (stone, brick, etc.) themselves. The common materials of masonry construction are bricks and building stone, rocks such as marble, granite, and limestone, cast stone, concrete blocks, glass blocks, and adobe. 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 substantially affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer. These are both classified as construction trades. History Masonry is one of the oldest building crafts in the world. The construction of Egyptian pyramids, Roman aqueducts, and medieval cathedrals are all examples of m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freemasonry
Freemasonry (sometimes spelled Free-Masonry) consists of fraternal groups that trace their origins to the medieval guilds of stonemasons. Freemasonry is the oldest secular fraternity in the world and among the oldest still-existing organizations in history. Modern Freemasonry broadly consists of three main traditions: *Anglo-American Freemasonry, Anglo-American style Freemasonry, which insists that a "volume of sacred law", such as the Bible, Quran, or other religious text be open in a working Masonic lodge, lodge, that every member professes belief in a God, supreme being, that only men be admitted, and discussion of religion or politics does not take place within the lodge. *Continental Freemasonry or Liberal Freemasonry which has continued to evolve beyond these restrictions, particularly regarding religious belief and political discussion. *Co-Freemasonry, Women Freemasonry or Co-Freemasonry, which includes organizations that either admit women exclusively (such as the Ord ...

Rebar
Rebar (short for reinforcement bar or reinforcing bar), known when massed as reinforcing steel or steel reinforcement, is a tension device added to concrete to form ''reinforced concrete'' and reinforced masonry structures to strengthen and aid the concrete under tension. Concrete is strong under compression, but has low tensile strength. Rebar usually consists of steel bars which significantly increase the tensile strength of the structure. Rebar surfaces feature a continuous series of ribs, lugs or indentations to promote a better bond with the concrete and reduce the risk of slippage. The most common type of rebar is carbon steel, typically consisting of hot-rolled round bars with deformation patterns embossed into its surface. Steel and concrete have similar coefficients of thermal expansion, so a concrete structural member reinforced with steel will experience minimal differential stress as the temperature changes. Other readily available types of rebar are manufacture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flemish Bond
Flemish bond is a pattern of brickwork that is a common feature in Georgian architecture. The pattern features bricks laid lengthwise (''stretchers'') alternating with bricks laid with their shorter ends exposed (''headers'') within the same courses. This decorative pattern can be accented by glazing or burning the exposed ends of the headers so that they possess a dark, glassy surface that contrasts with the stretchers. Despite the bond's name, the pattern did not originate in Flanders and can be found in European architecture dating to the late Middle Ages. The pattern became popular among prestigious architectural projects in 17th-century England before spreading to British colonies in North America where it became closely associated with colonial Georgian architecture, especially in Virginia and Pennsylvania. With the early 20th-century restoration project at Colonial Williamsburg, the pattern experienced renewed popularity in the United States. Name Despite being called " ...

Wythe
A wythe is a continuous vertical section of masonry one unit in thickness. A wythe may be independent of, or interlocked with, the adjoining wythe(s). A single wythe of brick that is not structural in nature is referred to as a masonry veneer. A multiple-wythe masonry wall may be composed of a single type of masonry unit layered to increase its thickness and structural strength, or different masonry units chosen by function, such as an economical concrete block serving a structural purpose and a more expensive brick chosen for its appearance. In the Eurocodes The Eurocodes are the ten European standards (EN; harmonised technical rules) specifying how Structural engineering, structural design should be conducted within the European Union (EU). These were developed by the European Committee for Standar ..., the continuous vertical section is referred to as a ''leaf''. A single-leaf wall is a wall without a cavity or continuous vertical joint in its plane. A double-leaf wall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brick Work 2015-02-8 278
A brick is a type of construction material used to build walls, pavements and other elements in masonry construction. Properly, the term ''brick'' denotes a unit primarily composed of clay. But is now also used informally to denote building units made of other materials or other chemically cured construction blocks. Bricks can be joined using Mortar (masonry), mortar, adhesives or by interlocking. Bricks are usually produced at brickworks in numerous classes, types, materials, and sizes which vary with region, and are produced in bulk quantities. Concrete masonry unit, ''Block'' is a similar term referring to a rectangular building unit composed of clay or concrete, but is usually larger than a brick. Lightweight bricks (also called lightweight blocks) are made from expanded clay aggregate. Fired bricks are one of the longest-lasting and strongest building materials, sometimes referred to as artificial stone, and have been used since . Air-dried bricks, also known as mudbricks ...
