HABITAT 67, or simply Habitat, is a housing complex at Cit du Havre, on the Saint Lawrence River, Montreal, Quebec, Canada, designed by Israeli-Canadian architect Moshe Safdie.It originated in his master's thesis at the School of Architecture at McGill University and then an amended version was built for Expo 67, a World's Fair held from April to October 1967. Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.Ground-granulated blast furnace slag is a latent hydraulic binder forming calcium silicate hydrates (C-S-H) after The aggregates used for Concrete Products Ready Mixed Concrete Sand & Gravel Double tees are manufactured from prestressed concrete using pretensioning beds of about 200-foot (61 m) to 500-foot (150 m) long. The world's longest span in concrete has been the Brotonne Bridge over the Seine in France, which is a cable-stayed structure with a prestressed concrete deck and a main span of 1050 ft (320 m).The longest span concrete arch bridge is the Gladesville Bridge in Australia, completed in 1964, which has a span of 1000 ft (305 m) and a rise of 134 ft (40.8 m). A railroad tie, crosstie (American English), railway tie (Canadian English) or railway sleeper (Australian and British English) is a rectangular support for the rails in railroad tracks.Generally laid perpendicular to the rails, ties transfer loads to the track ballast and subgrade, hold the rails upright and keep them spaced to the correct gauge.

Significant stress may exist even when deformation is negligible or non-existent (a common assumption when modeling the flow of water). Many depend on circumstances. The floor systems are mostly built from pre-topped double tees. Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during production, in a manner that strengthens it against tensile forces which will exist when in service.
