We talk of the fuel irradiation as so many Megawatt.days/tonne, and that is a limiting factor on how much energy you will get from a tonne of fuel. However pile irradiation must represent the total Megawatt.days achieved from a particular reactor. In the early days of reactor experiments reactors were often referred to as piles, as they were literally piles of graphite bricks arranged with holes for fuel rods and control rods.
In hot rolling mills the steel bar is passed through a high pressure water quenching system whereby only the peripheral temperature is drastically reduced while the core remains largely unaffected. On leaving the specially designed quenching system, the core heat tempers the peripheral martensite that was formed during quenching. This results in a rebar with a soft core and a uniform hardened tempered martensite periphery - a rebar with high yield strength but with extremely good ductility. Such rebars are ideal for use in high hazard seismic areas.
These bars are produced in bar rolling mills by use of the globally proven and accepted THERMEX Quenching System and Technology of M/s HSE Germany.
In the Indian Region comprising India, Nepal, Bhutan, Bangladesh, Myanmar, Pakistan and Sri Lanka, M/s H&K Rolling Mill Engineers Pvt. Ltd., Mumbai (H&K India) have been given perpetual exclusive rights by HSE Germany to Licence, sell, market, install and commission the unique THERMEX Quenching Systems. As on 1 April 2013, H&K India has received orders for nearly 200 Thermex Systems to be set up in rolling mills - of which about 29 were under excecution. The installed capacity of Thermex QST rebars in India alone is over 14 million tonnes (65% market share). Each Thermex Licensee in Indian Region is subject to strict quarterly audit. Qualified QST engineers visit each Licensee to ensure that the rebar properties are as per the strict standards laid down by HSE Germany and H&K India besides meeting the Standrards of the country.
The Thermex 500 QST rebar meets most global standards and codes and is widely accepted by leading users of rebars because of the uniform properties obtained from the various Thermex Licensees.
In India, the registered trade mark/name THERMEX is owned by H&K India as per permission given by HSE Germany.
Unfortunately, in India, these QST rebars are incorrectly referred to as 'TMT' bars. 'TMT' is an acronym for Thermo-Mechanically Treatment even though no mechanical treatment is involved in the process. This has lead to a number of improper 'TMT' rebars being sold in India with non-uniform tempered martensite periphery at the rebar cross-section - encouraged by this non-uniformity "not being a ground for rejection" as per latest rebar code IS:1786-2008!

Fine aggregates are the aggregates whose size is less than 4.75 mm.
Example: Sand is used as fine aggregate in the preparation of concrete and cement mortar.
Workability refers to the ease of which the soil can be physically controlled for the purpose of cultivation. For example, if tilling or digging the soil produces cloddy or plate like clumps, the workability is low. From what I already know, clay soils aren't the best in terms of workability because it clumps together and is difficult to break up, whilst sandy soils usually have a much better workability but tend to be poor for cultivation because of other reasons.
The compressive stress allowed is 25N/mm2. However, the strength of a concrete element depends on the arrangement of loads. For compression, the element might buckle before it reaches its compressive stress.

this stirrups can be used in wide beams more than 25 cm 4-legged that mean the number of steel bar vertical are 4 or two stirrups intersection longitudinal
pad footing is the base of a column that transfers the load to the foundation.
Free carbon in cast iron refers to carbon that exists in its elemental form within the iron matrix. It appears as graphite flakes or nodules, contributing to the material's unique properties, such as high fluidity during casting and improved machinability. This free carbon distinguishes cast iron from other metals.
The minimum water requirement for initiating the chemical reaction between water and cement is known as the consistency of cement. This particular test is conducted to determine the minimum amount of water needed to form a cement paste.
The city of Pittsburgh, PA has 446 bridges. Some of its major bridges are the Fort Pitt Bridge, the Panhandle Bridge, the Smithfield Street Bridge, and the Liberty Bridge.
Two causeways, twenty-three miles in length, cross the lake and form the longest bridge in the world.
The type of bridges are:
-arch bridge (truss arch bridge)
-suspension bridge (suspension truss bridge)
Strength--Steel is very strong Flexibility--Ability to flex in the wind Cost--Inexpensive and fast to build; prefab construction Concrete, a possible alternative, has less compressive strength than steel. The bottom support structure of the empire state building would consist of a large percentage of solid concrete simply to support the weight of the building.
The largest stone bridge is located on Uzunkopru, Edirne, Turkey. The bridge has been built on the 15th century and 1.392 metres long as well as 6.80 metres wide.
Humber Bridge was created in 1981.
It's a late nineteenth century Bascule - twin leaf at that. It is a sort of prefabricated Suspension bridge with the bascule machinery in the towers for the two folding leaves.
This is a description of Tower Bridge - not London Bridge.
It's also not a suspension bridge. A suspension bridge has a deck suspended from cables, and cannot be opened. The rest of the technical description is correct.
Tension and compression are the two forces that act upon a bridge.
