It
545-426: A brick wall with windows, while the northern facade has two arches. The western facade contains fourteen bays and is a simpler version of its counterpart on the east. The recreation center was intended to double as a bathhouse and an enclosed play area. The ground-floor lobby of the recreation center contains a glass ticket booth between the two main doorways, where visitors originally purchased tickets for admission to
654-419: A comparatively small doorway, and faded letters reading colonial park and play center . The six bays on either side contain narrower arches separated by small full-height buttresses. Inside the narrower arches are various windows and doors, arranged according to the interior use. The ends of the bathhouse contain large cylindrical buttresses similar to those flanking the main entrance. The southern facade has
763-972: A dry, small aggregate concrete which is formed in steel moulds by vibration and compaction in either an "egglayer" or static machine. The finished blocks are cured, rather than fired, using low-pressure steam. Concrete bricks and blocks are manufactured in a wide range of shapes, sizes and face treatments – a number of which simulate the appearance of clay bricks. Concrete bricks are available in many colours and as an engineering brick made with sulfate-resisting Portland cement or equivalent. When made with adequate amount of cement they are suitable for harsh environments such as wet conditions and retaining walls. They are made to standards BS 6073, EN 771-3 or ASTM C55. Concrete bricks contract or shrink so they need movement joints every 5 to 6 metres, but are similar to other bricks of similar density in thermal and sound resistance and fire resistance. Compressed earth blocks are made mostly from slightly moistened local soils compressed with
872-635: A federal agency created as part of the New Deal to combat the Depression's negative effects. Eleven of these pools were to be designed concurrently and open in 1936. Moses, along with architects Aymar Embury II and Gilmore David Clarke , created a common design for these aquatic centers. Each location was to have distinct pools for diving, swimming, and wading; bleachers and viewing areas; and bathhouses with locker rooms that could be used as gymnasiums. The pools were to have several common features, such as

Bricks are laid in courses and numerous patterns known as bonds , collectively known as brickwork , and may be laid in various kinds of mortar to hold the bricks together to make a durable structure. The earliest bricks were dried mudbricks , meaning that they were formed from clay-bearing earth or mud and dried (usually in
1090-457: A kiln which makes them durable. Modern, fired, clay bricks are formed in one of three processes – soft mud, dry press, or extruded. Depending on the country, either the extruded or soft mud method is the most common, since they are the most economical. Clay and shale are the raw ingredients in the recipe for a fired brick. They are the product of thousands of years of decomposition and erosion of rocks, such as pegmatite and granite , leading to

1635-552: A project to restore the pools in several parks in 1977, including at Jackie Robinson Park, for whose restoration the agency set aside an estimated $ 2.6 million. The pool closed for renovation in 1978, and the park was renamed after Jackie Robinson the same year. The pool reopened in July 1980 after a $ 2.6 million renovation funded partially by the United States federal government. NYC Parks continued to face financial shortfalls in
1744-483: A relatively low embodied energy and carbon footprint . The ingredients are first harvested and added together, with clay content ranging from 30% to 70%. The mixture is broken up with hoes or adzes , and stirred with water to form a homogenous blend. Next, the tempers and binding agents are added in a ratio, roughly one part straw to five parts earth to reduce weight and reinforce the brick by helping reduce shrinkage. However, additional clay could be added to reduce

In 2019, the highest concentrations of felony assaults in Hamilton Heights were near the intersection of 135th Street and Broadway , where there were 10 felony assaults, and near
5123-405: The brick pile. Historically, a stack of unfired bricks covered for protection from the weather was called a "hack". Cooled finished bricks are removed from the other end for transport to their destinations. In the middle, the brick workers create a firing zone by dropping fuel (coal, wood, oil, debris, etc.) through access holes in the roof above the trench. The constant source of fuel maybe grown on
5232-465: The bricks are fired as they move slowly through the kiln on conveyors , rails, or kiln cars, which achieves a more consistent brick product. The bricks often have lime , ash, and organic matter added, which accelerates the burning process. The other major kiln type is the Bull's Trench Kiln (BTK), based on a design developed by British engineer W. Bull in the late 19th century. An oval or circular trench

9919-476: The sun for three days on both sides. After the six days, the bricks continue drying until required for use. Typically, longer drying times are preferred, but the average is eight to nine days spanning from initial stages to its application in structures. Unfired bricks could be made in the spring months and left to dry over the summer for use in the autumn. Mudbricks are commonly employed in arid environments to allow for adequate air drying. Fired bricks are baked in
10028-494: The sun) until they were strong enough for use. The oldest discovered bricks, originally made from shaped mud and dating before 7500 BC, were found at Tell Aswad , in the upper Tigris region and in southeast Anatolia close to Diyarbakir . Mudbrick construction was used at Çatalhöyük , from c. 7,400 BC. Mudbrick structures, dating to c. 7,200 BC have been located in Jericho , Jordan Valley. These structures were made up of
10137-437: The temperature inside the kiln stayed at a level that caused the clay to shimmer with the colour of molten gold or silver. He also had to know when to quench the kiln with water so as to produce the surface glaze. To anonymous labourers fell the less skilled stages of brick production: mixing clay and water, driving oxen over the mixture to trample it into a thick paste, scooping the paste into standardised wooden frames (to produce
10246-414: The term brick denotes a unit primarily composed of clay , but is now also used informally to denote units made of other materials or other chemically cured construction blocks. Bricks can be joined using 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. Block
10355-560: The third century BC, when baked bricks of regular shape began to be employed for vaulting underground tombs. Hollow brick tomb chambers rose in popularity as builders were forced to adapt due to a lack of readily available wood or stone. The oldest extant brick building above ground is possibly Songyue Pagoda , dated to 523 AD. By the end of the third century BC in China, both hollow and small bricks were available for use in building walls and ceilings. Fired bricks were first mass-produced during
10464-466: The time he was in office, several hundred such projects were underway across the city. Moses was especially interested in creating new pools and other bathing facilities, such as those in Jacob Riis Park , Jones Beach , and Orchard Beach . He devised a list of 23 pools around the city, including one in Harlem. The pools would be built using funds from the Works Progress Administration (WPA),
10573-500: The transition to Baroque architecture . In Lübeck , for example, Brick Renaissance is clearly recognisable in buildings equipped with terracotta reliefs by the artist Statius von Düren, who was also active at Schwerin ( Schwerin Castle ) and Wismar (Fürstenhof). Long-distance bulk transport of bricks and other construction equipment remained prohibitively expensive until the development of modern transportation infrastructure, with
10682-625: The trench. The colour of fired clay bricks is influenced by the chemical and mineral content of the raw materials, the firing temperature, and the atmosphere in the kiln. For example, pink bricks are the result of a high iron content, white or yellow bricks have a higher lime content. Most bricks burn to various red hues; as the temperature is increased the colour moves through dark red, purple, and then to brown or grey at around 1,300 °C (2,370 °F). The names of bricks may reflect their origin and colour, such as London stock brick and Cambridgeshire White. Brick tinting may be performed to change
10791-642: The turn of the 20th century led to a much greater use of cast and wrought iron , and later, steel and concrete . The use of brick for skyscraper construction severely limited the size of the building – the Monadnock Building , built in 1896 in Chicago, required exceptionally thick walls to maintain the structural integrity of its 17 storeys. Following pioneering work in the 1950s at the Swiss Federal Institute of Technology and
10900-437: The turn of the century, crimes such as sexual assaults had decreased in parks citywide due to increased security. Volunteers had also started planting greenery within Jackie Robinson Park by the end of the 1990s.

Proper brick construction, for erecting walls and vaults , finally emerges in
11118-562: The west and Bradhurst Avenue to the east. A group of three commissioners was appointed to oversee land acquisition. Due to various legal disputes, the land acquisition was not completed until 1899. The land acquisition was estimated to cost $ 1.5 million for 192 parcels, although the New York City government initially opposed the appropriations, stating that some plots were valued at much higher prices than they were actually worth. Colonial Park, and later Colonial Pool, were so named because several American Revolutionary War battles had taken place in

11336-518: Was a uniformity to the brick sizes throughout the Indus Valley region, conforming to the 1:2:4, thickness, width, and length ratio. As the Indus civilization began its decline at the start of the second millennium BC, Harappans migrated east, spreading their knowledge of brickmaking technology. This led to the rise of cities like Pataliputra , Kausambi , and Ujjain , where there was an enormous demand for kiln-made bricks. By 604 BC, bricks were
11445-750: Was hot, filthy work. Early civilisations around the Mediterranean , including the Ancient Greeks and Romans , adopted the use of fired bricks. By the early first century CE, standardised fired bricks were being heavily produced in Rome. The Roman legions operated mobile kilns , and built large brick structures throughout the Roman Empire , stamping the bricks with the seal of the legion. The Romans used brick for walls, arches, forts, aqueducts, etc. Notable mentions of Roman brick structures are
11554-517: Was only starting in the ninth century CE when buildings were entirely constructed using fired bricks. The carpenter's manual Yingzao Fashi , published in 1103 at the time of the Song dynasty described the brick making process and glazing techniques then in use. Using the 17th-century encyclopaedic text Tiangong Kaiwu , historian Timothy Brook outlined the brick production process of Ming dynasty China: ...the kilnmaster had to make sure that
11663-686: Was patented in 1853. Bradley & Craven went on to be a dominant manufacturer of brickmaking machinery. Henry Clayton, employed at the Atlas Works in Middlesex , England, in 1855, patented a brick-making machine that was capable of producing up to 25,000 bricks daily with minimal supervision. His mechanical apparatus soon achieved widespread attention after it was adopted for use by the South Eastern Railway Company for brick-making at their factory near Folkestone . At
11772-417: Was the tenth of these pools to open, although, at the time, the bathhouse was only partially completed. The pool opened on August 8, 1936, with performances by Bojangles Robinson and the 369th Regiment Band ; the ceremony was attended by over 25,000 people. Additional ballfields and courts were opened in October 1936, without any formal ceremony. The bandshell and dance terrace opened in July 1937, followed by
11881-481: Was used mostly by white residents of Italian Harlem . Embury filed construction plans for the bathhouse in October 1935, and a temporary bandshell was built the same year. The first improvement to be completed at Colonial Park was the playground at 152nd Street, which opened in April 1936. By mid-1936, ten of the eleven WPA-funded pools were completed and were being opened at a rate of one per week. The Colonial Park Pool
