Concrete buildings

Type I (Normal). This is the general purpose Pordand cement used for all appHcations where special properties are not needed. Common appHcations include concretes for paving, building doors, roof decks, reinforced concrete buildings, pipes, tanks, bridges, and other precast concrete products. In 1989 Type I and Type II accounted for over 92% of the Pordand cement produced in U.S. plants. Exact data are not available that separate Type I and Type II Pordand cement, but it can be assumed that Type I production was much greater than Type II. 

Fabricating - Steel sections are cut, welded and otherwise prepared to form the steel frame of a building. Rods and bars are similarly cut and shaped to form the steel reinforcement for concrete buildings.

Is fire fighting and safety equipment properly located and maintained Yes. This system is on a concrete building roof. Because there are no flammable materials involved in this system, if a fne occurs, there will be no special effort by fire fighting crews to concentrate on the roof area. 

The primary failure mechanisms encountered in reinforced concrete buildings arc flexure, diagonal tension, and direct shear. Of these three mechanisms,. flexure is preferred under blast loading because an extended plastic response is provider prior to failure. To assure a ductile response, sections are designed so that the flexural capacity is less than the capacity of non-ductile mechanisms.

An Igloo is a concrete building of semi-cylindrical shape with the axis on the ground and with earth covering the arched roof and piled up against the sides. This earth acts as a barricade and also serves to conceal the Igloo as much as possible from view... 

A concrete building procedure in three dimensions of the Wigner-Seitz cell can be achieved by representing lines from a lattice point to others in the lattice and then drawing planes that cut in half each of the represented lines, and finally taking the minimum polyhedron enclosing the lattice point surrounded by the constructed planes. 

Values for brick buildings and 3.5-fold exchange of air per hour. In concrete buildings without exchange of air the values are higher by a factor of 4-7.

It is essential that people and the surrounding countryside be adequately shielded from possible exposure to radioactive nuclides. The entire reactor is enclosed in a steel containment vessel. This is housed in a thick-walled concrete building. The operating personnel are further protected by a so-called biological shield, a thick layer of organic material made of compressed wood fibers. This absorbs the neutrons and beta and gamma rays that would otherwise be absorbed in the human body.

The cells are operated in a metal and concrete building, not sprinkler-protected and free of water or steam pipes. Operating personnel wear head shields, goggles, face masks, asbestos gloves, duck aprons, and loose-fitting coveralls. If metal is spilled on the skin, personnel are instructed to flood the area with oil, then report promptly for medical examination. 

To avoid deterioration of the bags by moisture and of the hydrated lime by re-carbonation, bagged hydrate should be stored under cover. The ideal store is a brick or concrete building constructed to minimise draughts. It should have a low roof to minimise internal air space and be unheated. Under such conditions, bagged hydrate can be stored for a year without significant deterioration [21.1].
