A hold-down may also refer to clamping device used to anchor a pipe to a structural steel element or concrete floor or allow movement of the pipe in an axial direction. [1] At the bottom, the hold down is connected to the concrete foundation or structural slab by an embedded or epoxied anchor bolt. At the top, the hold down is connected to a ...
Creep and shrinkage of concrete are two physical properties of concrete. The creep of concrete, which originates from the calcium silicate hydrates (C-S-H) in the hardened Portland cement paste (which is the binder of mineral aggregates), is fundamentally different from the creep of metals and polymers.
The initiation time is related to the rate at which carbonation propagates in the concrete cover thickness.Once that carbonation reaches the steel surface, altering the local pH value of the environment, the protective thin film of oxides on the steel surface becomes instable, and corrosion initiates involving an extended portion of the steel surface.
Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]
The Alcatel mandatory standstill period is a period of at least ten calendar days following the notification of an award decision in a contract tendered via the Official Journal of the European Union, before the contract is signed with the successful supplier(s). Its purpose is to allow unsuccessful bidders to challenge the decision before the ...
Floor plans use standard symbols to indicate features such as doors. This symbol shows the location of the door in a wall and which way the door opens. A floor plan is not a top view or bird's-eye view; it is a measured drawing to scale of the layout of a floor in a building.
Concrete floors were found in the royal palace of Tiryns, Greece, which dates roughly to 1400 to 1200 BC. [11] [12] Lime mortars were used in Greece, such as in Crete and Cyprus, in 800 BC. The Assyrian Jerwan Aqueduct (688 BC) made use of waterproof concrete. [13] Concrete was used for construction in many ancient structures. [14]
The test is carried out using a metal mould in the shape of a conical frustum known as a slump cone or Abrams cone, that is open at both ends and has attached handles.The tool typically has an internal diameter of 100 millimetres (3.9 in) at the top and of 200 millimetres (7.9 in) at the bottom with a height of 305 millimetres (12.0 in).The cone is placed on a hard non-absorbent surface.
