Tezontle
Tezontle ( es, tezontle) is a porous, highly oxidized, volcanic rock used extensively in construction in Mexico. It is usually reddish in color due to iron oxide. Tezontle is a well-cemented, agglomeritic and scoriaceous rock. Uses Construction Tezontle can be mixed with concrete to form lightweight concrete blocks, or mixed with cement to create stucco finishes. Many colonial buildings in Mexico use the reddish cut tezontle on their facades. Tezontle is a common construction material in the Historic Center of Mexico City as the relatively light-weight stone helps impede a building from sinking into the unstable lake bed on which Mexico City was built. Other uses Non-building uses include its inclusion in flower arrangements and botanical gardens, as substrate for aquariums, and for temazcales and ovens. Tezontle is often used as the top layer of gravel on unpaved roads in Mexico. Facades Many buildings use tezontle to create an aesthetic facade. Here are some examples. * ...

Mexico City Metropolitan Cathedral
The Metropolitan Cathedral of the Assumption of the Most Blessed Virgin Mary into Heaven ( es, Catedral Metropolitana de la Asunción de la Bienaventurada Virgen María a los cielos) is the cathedral church of the Roman Catholic Archdiocese of Mexico. It is situated on top of the former Aztec sacred precinct near the Templo Mayor on the northern side of the Plaza de la Constitución (Zócalo) in the historic center of Mexico City. The cathedral was built in sections from 1573 to 1813 around the original church that was constructed soon after the Spanish conquest of Tenochtitlan, eventually replacing it entirely. Spanish architect Claudio de Arciniega planned the construction, drawing inspiration from Gothic cathedrals in Spain. Due to the long time it took to build it, just under 250 years, virtually all the main architects, painters, sculptors, gilding masters and other plastic artists of the viceroyalty worked at some point in the construction of the enclosure. The long constr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Palace (Mexico)
The National Palace ( es, Palacio Nacional) is the seat of the federal executive in Mexico. Since 2018 it has also served as the official residence for the President of Mexico. It is located on Mexico City's main square, the Plaza de la Constitución ('' El Zócalo''). This site has been a palace for the ruling class of Mexico since the Aztec Empire, and much of the current palace's building materials are from the original one that belonged to the 16th-century leader Moctezuma II. Current complex Used and classified as a government building, the National Palace, with its red tezontle facade, fills the entire east side of the Zócalo, measuring over long.

Church Of San Bernardo, Mexico City
The Church of San Bernardo ( es, link=no, Iglesia de San Bernardo) stands at the corner of Avenida 20 de Noviembre and Venustiano Carranza Street just south of the Zocalo or main plaza of Mexico City. It was part of a convent of the same name that was founded in 1636, but was closed along with all convents and monasteries during the La Reforma period in 1861. Currently, only the church remains of the convent complex. The church was built between 1685 and 1687 in Baroque style. Description The church was part of a convent of the same name which was sponsored by Juan Marquez de Orozco, a merchant who left his fortune to the Church with the stipulation that the money be used to found a convent for the Cistercian Order.

Historic Center Of Mexico City
The historic center of Mexico City ( es, Centro Histórico de la Ciudad de México), also known as the Centro or Centro Histórico, is the central neighborhood in Mexico City, Mexico, focused on Zócalo or main plaza and extending in all directions for a number of blocks, with its farthest extent being west to the Alameda Central. The Zocalo is the largest plaza in Latin America. It can hold up to nearly 100,000 people. This section of the capital lies in the municipal borough of Cuauhtémoc, has just over nine square km and occupies 668 blocks. It contains 9,000 buildings, 1,550 of which have been declared of historical importance. Most of these historic buildings were constructed between the 16th and 20th centuries. It is divided into two zones for preservation purposes. Zone A encompasses the pre-Hispanic city and its expansion from the Viceroy period until Independence. Zone B covers the areas all other constructions to the end of the 19th century that are considered indispens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nacional Monte De Piedad
The Nacional Monte de Piedad is a not-for-profit institution and pawnshop whose main office is located just off the Zócalo, or main plaza of Mexico City. It was commanded to be built between 1774 and 1777 by Don Pedro Romero de Terreros, the Count of Regla as part of a movement to provide interest-free or low-interest loans to the poor. It was recognized as a national charity in 1927 by the Mexican government. In the first decade of the 21st century, it is a fast-growing institution, with over 200 branches all over Mexico and plans to open a branch in every Mexican city. Main office The main office is located on the northwest corner of the Zocalo on the corner of Monte de Piedad and 5 de Mayo Streets. Despite having gone through considerable modifications, it once was part of the estate owned by Hernán Cortés (1485–1547). In the area were the "Old Houses" of Moctezuma II's father, Axayacatl (1453?-1483). At the time of Cortes’ arrival, Moctezuma lived in the "New Houses" a ...

Lake Texcoco
Lake Texcoco ( es, Lago de Texcoco) was a natural lake within the "Anahuac" or Valley of Mexico. Lake Texcoco is best known as where the Aztecs built the city of Tenochtitlan, which was located on an island within the lake. After the Spanish conquest of the Aztec Empire, efforts to control flooding by the Spanish led to most of the lake being drained. The entire lake basin is now almost completely occupied by Mexico City, the capital of the present-day nation of Mexico. Drainage of the lake has led to serious ecological and human consequences: the local climate and water availability have changed considerably, contributing to water scarcity in the area; subsequent groundwater extraction leads to land subsidence under much of the city; and native species endemic to the lake region have become severely endangered or extinct due to ecosystem change, such as the axolotl. After the cancellation of the Mexico City Texcoco Airport, the government initiated a major restoration project ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House Of Count De La Torre De Cossio
A house is a single-unit residential building. It may range in complexity from a rudimentary hut to a complex structure of wood, masonry, concrete or other material, outfitted with plumbing, electrical, and heating, ventilation, and air conditioning systems.Schoenauer, Norbert (2000).

Temazcal
A temazcal is a type of sweat lodge, which originated with pre-Hispanic indigenous peoples in Mesoamerica. The term ''temazcal'' comes from the Nahuatl language, either from the words (to bathe) and (house), or from the word (house of heat). Overview In ancient Mesoamerica it was used as part of a curative ceremony thought to purify the body after exertion such as after a battle or a ceremonial ball game. It was also used for healing the sick, improving health, and for women to give birth. It continues to be used today in Indigenous cultures of Mexico and Central America that were part of the ancient Mesoamerican region for spiritual healing and health enrichment reasons. The temazcal is usually a permanent structure, unlike sweat lodges of other regions. It has various construction styles differing by region; from volcanic rock and cement adobe mud bricks even wood mud and cloth can be utilized. It may be a circular dome made to represent the uterus, although rectangular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Substrate (aquarium)
The substrate of an aquarium refers to the material used on the tank bottom. It can affect water chemistry, filtration, and the well-being of the aquarium's inhabitants, and is also an important part of the aquarium's aesthetic appeal. The appropriate substrate depends on the type of aquarium; the most important parameter is whether the aquarium contains fresh water or saltwater. Functions and considerations Substrates are added to most aquaria principally for the increase in beneficial bacteria this provides. However, substrates can also have a variety of direct effects on water quality by releasing substances into the water, absorbing substances from the water, or reacting chemically with substances from other sources. Substrates can also have indirect effects on a system's health; dark-colored substrates, for example, are considered by some to be better for fish, as the fish display more colorfully by comparison, and are less likely to behave timidly. Apart from all other consid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porosity
Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam). There are many ways to test porosity in a substance or part, such as industrial CT scanning. The term porosity is used in multiple fields including pharmaceutics, ceramics, metallurgy, materials, manufacturing, petrophysics, hydrology, earth sciences, soil mechanics, and engineering. Void fraction in two-phase flow In gas-liquid two-phase flow, the void fraction is defined as the fraction of the flow-channel volume that is occupied by the gas phase or, alternatively, as the fraction of the cross-sectional area of the channel that is occupied by the gas phase. Void fraction usually varies from location to location in the flow ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stucco
Stucco or render is a construction material made of aggregates, a binder, and water. Stucco is applied wet and hardens to a very dense solid. It is used as a decorative coating for walls and ceilings, exterior walls, and as a sculptural and artistic material in architecture. Stucco can be applied on construction materials such as metal, expanded metal lath, concrete, cinder block, or clay brick and adobe for decorative and structural purposes. In English, "stucco" sometimes refers to a coating for the outside of a building and "plaster" to a coating for interiors; as described below, however, the materials themselves often have little to no differences. Other European languages, notably Italian, do not have the same distinction; ''stucco'' means ''plaster'' in Italian and serves for both. Composition The basic composition of stucco is cement, water, and sand. The difference in nomenclature between stucco, plaster, and mortar is based more on use than composition. Until ...
