Masonry
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 (masonry), 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, rock (geology), rocks such as marble, granite, and limestone, cast stone, concrete masonry unit, concrete blocks, glass brick, 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 worker, construction trades. History Masonry is one of the oldest building crafts in the world. The constructio ... [...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 ...

Concrete Masonry Unit
A concrete block, also known as a cinder block in North American English, breeze block in British English, or concrete masonry unit (CMU), or by various other terms, is a standard-size rectangular block used in building construction. The use of blockwork allows structures to be built in the traditional masonry style with layers (or courses) of staggered blocks. Concrete blocks may be produced with hollow centers (cores) to reduce weight, improve insulation and provide an interconnected void into which concrete can be poured to solidify the entire wall after it is built. Concrete blocks are some of the most versatile building products available because of the wide variety of appearances that can be achieved using them. Naming Those that use cinders (fly ash or bottom ash) as an aggregate material are called ''cinder blocks'' in the United States. They are also known as ''breeze blocks'', a term derived from ''breeze'', referring to the small cinders and cinder-dust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ashlar
Ashlar () is a cut and dressed rock (geology), stone, worked using a chisel to achieve a specific form, typically rectangular in shape. The term can also refer to a structure built from such stones. Ashlar is the finest stone masonry unit, and is generally rectangular (cuboid). It was described by Vitruvius as ''opus isodomum'' or trapezoidal. Precisely cut "on all faces adjacent to those of other stones", ashlar is capable of requiring only very thin joints between blocks, and the visible face of the stone may be Quarry-faced stone, quarry-faced or feature a variety of treatments: tooled, smoothly polished or rendered with another material for decorative effect. One such decorative treatment consists of small grooves achieved by the application of a metal comb. Generally used only on softer stone ashlar, this decoration is known as "mason's drag". Ashlar is in contrast to rubble masonry, which employs irregularly shaped stones, sometimes minimally worked or selected for simi ...

Brick
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 ...

Rubble Masonry
Rubble masonry or rubble stone is rough, uneven building stone not laid in regular courses. It may fill the core of a wall which is faced with unit masonry such as brick or ashlar. Some medieval cathedral walls have outer shells of ashlar with an inner backfill of mortarless rubble and dirt. Square rubble masonry Square rubble masonry consists of stones that are dressed (squared on all joints and beds) before laying, set in mortar, and make up the outer surface of a wall. History Irregular rubble, or sack, masonry evolved from embankments covered with boards, stones or bricks. That outer surface was used to give the embankment greater strength and make it more difficult for enemies to climb. The Sadd el-Khafara dam, in Wadi Al-Garawi near Helwan in Egypt, which is 14 meters high and built in rubble masonry, dates back to 2900–2600 BC The Greeks called the construction technique emplekton and made particular use of it in the construction of the defensive walls of ...

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] |
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] |
