The Catawba Nuclear Station, for instance, has been constructing a concrete moat around some of the plant ( other sides of the plant are bordering a lake ).

Perched on a hilltop site, with uninterrupted views across the whole of Acapulco Bay, the main living quarters are surmounted by a large open terrace with spectacular views of the beach and bay, encircled by a " sky moat " which snakes around its edge ; the terrace is itself topped by a huge, sweeping semi-circular angled awning made of cast, reinforced concrete.

Three concrete stelae, rising from a shallow moat, form the dramatic centre and enclose a space for quiet contemplation.

From the outside the chapel is a simple, windowless brick cylinder set inside a very shallow concrete moat.

In 1905 the District Works Office of the Dongjiao Embassy District covered the original moat with concrete.

It was reburied in the Vevey cemetery under 6 feet ( 1. 8 m ) of concrete.

Steel or reinforced concrete beams replace the connections to the foundations, while under these, the isolating pads, or base isolators, replace the material removed.

The Second Vatican Council did not speak of any of these concrete methods … This is a different standpoint than that taken under Pius XI some thirty years which was also maintained by his successor ... we can sense here a clear development in the Church, a development, which is also going on outside the Church.

Another form of girder is the reinforced concrete beam, in which metal rods are encased in concrete, giving it greater strength under tension.

If the hardened carrier is buried under ground, to secure cables running between buildings for example, the carrier containing the cables is encased in concrete.

" The body was buried under five feet of concrete and steel, making exhumation less likely.

Reinforced concrete may also be permanently stressed ( in compression ), so as to improve the behaviour of the final structure under working loads.

The reinforcement in a RC structure, such as a steel bar, has to undergo the same strain or deformation as the surrounding concrete in order to prevent discontinuity, slip or separation of the two materials under load.

Since the concrete is always under compression, it is less subject to cracking and failure.

The concrete then cracks either under excess loading, or due to internal effects such as early thermal shrinkage when it cures.

The Dunbar CB is nearest to Greencastle, which can be accessed via US 231 north, under the concrete railroad viaduct.

These were not designed to directly penetrate defences, though they could do this ( for example the Valentin submarine pens had ferrous concrete roofs 7 metres ( 23 ft ) thick which were penetrated by two Grand Slams on 27 March 1945 ), but rather to penetrate under the target and explode leaving a camouflet ( cavern ) which would undermine foundations of structures above, causing it to collapse, thus negating any possible hardening.

While penetrations of 20 – were sufficient for some shallow targets, both the Soviet Union and the United States were creating bunkers buried under huge volumes of soil or reinforced concrete in order to withstand the multi-megaton thermonuclear weapons developed in the 1950s and 1960s.

Like a floor on joists not on concrete, a second sheeting underlayment layer is added with staggered joints to disperse forces that would open a joint under the stress of live loads like a person walking.

Above the targeted bottom height ( coplanar with the compacted sand and gravel topping ) a separate grid of rebar or welded wire mesh is usually added to reinforce the concrete, and will be tied to the under slab ' girder ' rebar at intervals.

A young secretary named Charlotte Darehshori ran to help Boyer and Huffman only to find herself under fire from Whitman ; Darehshori crouched beneath the concrete base of a flagpole for an hour-and-a-half, shielding herself from Whitman's view.

Police and fire officials, who said that it would be highly unlikely for anyone else to have survived under the concrete, had evacuated nearby homes and businesses, where the power had been fluctuating.

This involved culverting the River Wye under concrete, and demolishing most of the old buildings in Wycombe's town centre.

In 1971 he became the chief of the Bureau of Engineering and Fortifications of the Ministry of Defense ( under Enver Hoxha when thousands of concrete casements were built as defense against states held to be hostile ).

Coal tunnel under construction using handset aluminum concrete forms.

There, he established a concrete testing laboratory under Charles E. Wuerpel which is now part of the Structures Laboratory at the Waterways Experiment Station at Vicksburg, Mississippi.

In 1995, the cause of the problem was discovered to be a slab of concrete under the stage.

It was initially built with a radiant heating system of hot water pipes under the Lower Box seats in a space between the concrete and the ground.

The primary use of asphalt is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete.

* Bad End 2-21st Century Hobbit Hole-Precast concrete in home construction

Hadrian's Pantheon, Rome | Pantheon in Rome is an example of Roman concrete construction.

Options for non-combustible construction include floors, ceilings and roofs made of cast-in-place and hollow-core precast concrete.

The amount of concrete used in the construction of the dam is estimated at 16 million cubic meters over 17 years.

The world record for concrete pumping was set on 7 August 2009 during the construction of the Parbati Hydroelectric Project, near the village of Suind, Himachal Pradesh, India, when the concrete mix was pumped through a vertical height of.

The use of concrete in construction grew rapidly from 1850 onward, and was soon the dominant use for cements.

As a construction material, concrete can be cast in almost any shape desired, and once hardened, can become a structural ( load bearing ) element.

As climbing form and table form construction method and efficient construction management are used in this project which make this reinforced concrete structure take no longer construction time than the steel structure.

Urbanization has major effects on erosion processes — first by denuding the land of vegetative cover, altering drainage patterns, and compacting the soil during construction ; and next by covering the land in an impermeable layer of asphalt or concrete that increases the amount of surface runoff and increases surface wind speeds.

Noteworthy technical achievements of Mountbatten and his staff include the construction of an underwater oil pipeline from the English coast to Normandy, an artificial harbour constructed of concrete caissons and sunken ships, and the development of amphibious tank-landing ships.

Increasingly popular alternative construction materials include insulating concrete forms ( foam forms filled with concrete ), structural insulated panels ( foam panels faced with oriented strand board or fiber cement ), and light-gauge steel framing and heavy-gauge steel framing.

Pei involved himself in the construction process at Kips Bay, even inspecting the bags of concrete to check for consistency of color.

The economy of Malmö was traditionally based on shipbuilding ( Kockums ) and construction related industries, such as concrete factories.

The common materials of masonry construction are brick, stone, marble, granite, travertine, limestone, cast stone, concrete block, glass block, stucco, and tile.

* Save for concrete, masonry construction does not lend itself well to mechanization, and requires more skilled labor than stick-framing.

Unfortunately for the kingfisher, a U. N. plan to protect the mangroves as a biological reserve was blatantly ignored by the emirate of Sharjah, which allowed the dredging of a channel that bisects the wetland and construction of an adjacent concrete walkway.

In concrete or steel construction, an exterior beam extending from column to column usually carrying an exterior wall load is known as a spandrel beam.

Some early skyscrapers have a steel frame that enables the construction of load-bearing walls taller than of those made of reinforced concrete.

* The concrete details of a given construction may be messy, but if the construction satisfies a universal property, one can forget all those details: all there is to know about the construct is already contained in the universal property.
