Dry Dock
A dry dock (sometimes drydock or dry-dock) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft. History Greco-Roman world The Greek author Athenaeus of Naucratis (V 204c-d) reports something that may have been a dry dock in Ptolemaic Egypt in the reign of Ptolemy IV Philopator (221-204 BC) on the occasion of the launch of the enormous ''Tessarakonteres'' rowing ship. It has been calculated that a dock for a vessel of such a size might have had a volume of 750,000 gallons of water. In Roman times, a shipyard at Narni, which is still studied, may have served as a dry dock. Medieval China The use of dry docks in China goes at least as far back the 10th century A.D. In 1088, Song Dynasty scientist and statesman Shen Kuo (1031–1095) wrote in his '' Dream Pool Essays'': Renais ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Simonstown Agreement
The Simonstown Agreement (sic) was a naval cooperation agreement between the United Kingdom of Great Britain and Northern Ireland and the (then-officially) Union of South Africa signed . Under the agreement, the Royal Navy (RN) gave up its naval base at Simon's Town, South Africa, and transferred command of the South African Navy (SAN) to the government of South Africa. In return, South Africa promised the use of the Simonstown base to Royal Navy ships. The agreement also permitted South Africa to buy six anti-submarine frigates, ten coastal minesweepers and four seaward defence boats from the UK valued at £18 million over the next eight years. In effect, the agreement was a mutual defence arrangement aimed at protecting sea routes between the UK and the Middle East. The agreement was controversial because of South Africa's policy of racial separation known as ''apartheid''. In the planning stages, the agreement was intended to include: * the combined use of Simon’s Tow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foundation Stone
The cornerstone (or foundation stone or setting stone) is the first stone set in the construction of a masonry foundation. All other stones will be set in reference to this stone, thus determining the position of the entire structure. Over time a cornerstone became a ceremonial masonry stone, or replica, set in a prominent location on the outside of a building, with an inscription on the stone indicating the construction dates of the building and the names of architect, builder, and other significant individuals. The rite of laying a cornerstone is an important cultural component of eastern architecture and metaphorically in sacred architecture generally. Some cornerstones include time capsules from, or engravings commemorating, the time a particular building was built. History The ceremony typically involved the placing of offerings of grain, wine and oil on or under the stone. These were symbolic of the produce and the people of the land and the means of their subsistence. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Portland Cement
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and is usually made from limestone. It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2 to 3 percent of gypsum. Several types of portland cement are available. The most common, called ordinary portland cement (OPC), is grey, but white Portland cement is also available. Its name is derived from its resemblance to Portland stone which was quarried on the Isle of Portland in Dorset, England. It was named by Joseph Aspdin who obtained a patent for it in 1824. His son William Aspdin is regarded as the inventor of "modern" portland cement due to his developments in the 1840s. The low cost and widespread availability of the limestone, shales ...

Naval Base Simon's Town
Naval Base Simon's Town is the South African Navy's largest naval base, situated at Simon's Town, near Cape Town. The base provides support functions to Fleet Command. History A small dockyard facility was first established in Simon's Town by the Dutch East India Company in 1743. This was taken over by the British Royal Navy (RN) in the 1790s, under whom the facility was further developed over the following century and a half. A pair of handsome stone storehouses dating from the 1740s stand on the seafront where they were built by the Dutch East India Company, marking the initial location of the Yard. Immediately adjacent is the earliest Royal Naval building on the site: a combined mast-house, boathouse and sail loft; dating from 1815, it now serves as the South African Naval Museum. Over the next few decades, the site was developed gradually, with steam engineering and coaling facilities being added mid-century. In 1885, the government of the Cape Colony transferred the ass ...
