A set of barrels can be used with a mono-strand stressed tendon as an alternative to an anchor block. block See anchor block. bond The adhesion of concrete or grout to prestressing strands, wires or bars, or to unstressed reinforcement, either through friction or mechanical interlock. [1]: 9 bond strength
A large number of Indian Standard (IS) codes are available that are meant for virtually every aspect of civil engineering one can think of. During one's professional life one normally uses only a handful of them depending on the nature of work they are involved in. Civil engineers engaged in construction activities of large projects usually have to refer to a good number of IS codes as such ...
SOD1 binds copper and zinc ions and is one of three superoxide dismutases responsible for destroying free superoxide radicals in the body. The encoded isozyme is a soluble cytoplasmic and mitochondrial intermembrane space protein, acting as a homodimer to convert naturally occurring, but harmful, superoxide radicals to molecular oxygen and hydrogen peroxide.
Post-tensioned concrete is a variant of prestressed concrete where the tendons are tensioned after the surrounding concrete structure has been cast. [ 1 ] : 25 The tendons are not placed in direct contact with the concrete, but are encapsulated within a protective sleeve or duct which is either cast into the concrete structure or placed ...
Surface processing techniques (e.g., washed concrete surfaces, photo concrete, acidified surfaces) can also be used to create the aesthetic of béton brut. Particularly high-quality poured concrete, achieved by leaving enough room between the formwork and the reinforcing bars for the concrete to flow freely, is called Sichtbeton in German and ...
TU/e Built Environment's Rohaco 3D Concrete Printer being extensively used for Concrete Printing Research. 3D concrete printing, or simply concrete printing, refers to digital fabrication processes for cementitious materials based on one of several different 3D printing technologies. 3D-printed concrete eliminates the need for formwork, reducing material waste and allowing for greater ...
A tetrapod is a form of wave-dissipating concrete block used to prevent erosion caused by weather and longshore drift, primarily to enforce coastal structures such as seawalls and breakwaters. Tetrapods are made of concrete , and use a tetrahedral shape to dissipate the force of incoming waves by allowing water to flow around rather than ...
Other manufacturers were thus compelled to use other terminology to describe the process such as shotcrete, pneumatic concrete, guncrete, etc. Shotcrete is an all-inclusive term for spraying concrete or mortar with either a dry or wet mix process. However, shotcrete may also sometimes be used to distinguish wet-mix from the dry-mix method.
