Opus Africanum
''Opus africanum'' is a form of ashlar masonry used in Carthaginian and ancient Roman architecture, characterized by pillars of vertical blocks of stone alternating with horizontal blocks, filled in with smaller blocks in between. Its name derives from the Roman province of Africa, and is common in North Africa, but also found in Sicily and Southern Italy.

Ashlar
Ashlar () is finely dressed (cut, worked) stone, either an individual stone that has been worked until squared, or a structure built from such stones. Ashlar is the finest stone masonry unit, generally rectangular cuboid, mentioned by Vitruvius as opus isodomum, or less frequently trapezoidal. Precisely cut "on all faces adjacent to those of other stones", ashlar is capable of very thin joints between blocks, and the visible face of the stone may be 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 similar size, or both. Ashlar is related but distinct from other stone masonry that i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Masonry
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 bricks, building stone 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. Applications Masonry is commonly used for walls and buildings. Brick and concrete block are the most common types of masonry in use in industrialized nations and may be either load-bearing or non-load-bearing. Concrete blocks, especially those with hollow cores, offer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roman Architecture
Ancient Roman architecture adopted the external language of classical Greek architecture for the purposes of the ancient Romans In modern historiography, ancient Rome refers to Roman civilisation from the founding of the city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 ..., but was different from Greek buildings, becoming a new architecture, architectural style. The two styles are often considered one body of classical architecture. Roman architecture flourished in the Roman Republic and to even a greater extent under the Roman Empire, Empire, when the great majority of surviving buildings were constructed. It used new materials, particularly Roman concrete, and newer technologies such as the arch and the dome to make buildings that were typically strong and well-engineered. Large numbers remain in some form across the former empire, sometimes complete and still in use to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa Province
Africa Proconsularis was a Roman province on the northern African coast that was established in 146 BC following the defeat of Carthage in the Third Punic War. It roughly comprised the territory of present-day Tunisia, the northeast of Algeria, and the coast of western Libya along the Gulf of Sirte. The territory was originally inhabited by Berber people, known in Latin as ''Mauri'' indigenous to all of North Africa west of Egypt; in the 9th century BC, Phoenicians built settlements along the Mediterranean Sea to facilitate shipping, of which Carthage rose to dominance in the 8th century BC until its conquest by the Roman Republic. It was one of the wealthiest provinces in the western part of the Roman Empire, second only to Italy. Apart from the city of Carthage, other large settlements in the province were Hadrumetum (modern Sousse, Tunisia), capital of Byzacena, and Hippo Regius (modern Annaba, Algeria).

North Africa
North Africa, or Northern Africa is a region encompassing the northern portion of the African continent. There is no singularly accepted scope for the region, and it is sometimes defined as stretching from the Atlantic shores of Mauritania in the west, to Egypt's Suez Canal. Varying sources limit it to the countries of Algeria, Libya, Morocco, and Tunisia, a region that was known by the French during colonial times as "''Afrique du Nord''" and is known by Arabs as the Maghreb ("West", ''The western part of Arab World''). The United Nations definition includes Morocco, Algeria, Tunisia, Libya, Egypt, Sudan, and the Western Sahara, the territory disputed between Morocco and the Sahrawi Republic. The African Union definition includes the Western Sahara and Mauritania but not Sudan. When used in the term Middle East and North Africa (MENA), it often refers only to the countries of the Maghreb. North Africa includes the Spanish cities of Ceuta and Melilla, and plazas de so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Roman Concrete
Roman concrete, also called , is a material that was used in construction in ancient Rome. Roman concrete was based on a hydraulic-setting cement. It is durable due to its incorporation of pozzolanic ash, which prevents cracks from spreading. By the middle of the 1st century the material was used frequently, often brick-faced, although variations in aggregate allowed different arrangements of materials. Further innovative developments in the material, called the concrete revolution, contributed to structurally complicated forms, such as the Pantheon dome, the world's largest and oldest unreinforced concrete dome. Roman concrete was normally faced with stone or brick, and interiors might be further decorated by stucco, fresco paintings, or thin slabs of fancy colored marbles. Made up of aggregate and a two-part cementitious system it differs significantly from modern concrete. The aggregates were typically far larger than in modern concrete as well, often amounting to rubble, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dougga
Dougga or Thugga or TBGG was a Berber, Punic and Roman settlement near present-day Téboursouk in northern Tunisia. The current archaeological site covers . UNESCO qualified Dougga as a World Heritage Site in 1997, believing that it represents "the best-preserved Roman small town in North Africa". The site, which lies in the middle of the countryside, has been protected from the encroachment of modern urbanization, in contrast, for example, to Carthage, which has been pillaged and rebuilt on numerous occasions. Dougga's size, its well-preserved monuments and its rich Numidian-Berber, Punic, ancient Roman and Byzantine history make it exceptional. Amongst the most famous monuments at the site are a Libyco-Punic Mausoleum, the Capitol, the Roman theatre, and the temples of Saturn and of Juno Caelestis. Names The Numidian name of the settlement was recorded in the Libyco-Berber alphabet as TBGG. The Punic name of the settlement is recorded as () and (). The Root B GG in Phoeni ...

Bricks
A brick is a type of block used to build walls, pavements and other elements in masonry construction. Properly, the term ''brick'' denotes a block composed of dried clay, but is now also used informally to denote other chemically cured construction blocks. Bricks can be joined using mortar, adhesives or by interlocking them. Bricks are usually produced at brickworks in numerous classes, types, materials, and sizes which vary with region and time period, and are produced in bulk quantities. ''Block'' is a similar term referring to a rectangular building unit composed of similar materials, 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 circa 4000 BC. Air-dried bricks, also known as mud-bricks, have a history older than fired bricks, and have an additi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients.
