  2. SOD1 - Wikipedia

    en.wikipedia.org/wiki/SOD1

    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.

    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

  4. Voided biaxial slab - Wikipedia

    en.wikipedia.org/wiki/Voided_biaxial_slab

    The overall mass of concrete can be reduced by 35–50% depending on the design, [1] as a consequence of reduced slab mass, as well as lower requirements for vertical structure and foundations. Biaxial slabs commonly span up to 20 metres at a thickness of around 500 mm. [ citation needed ] The added strength also reduces the acoustic ...

  5. Tetrapod (structure) - Wikipedia

    en.wikipedia.org/wiki/Tetrapod_(structure)

    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 ...

  6. Lift slab construction - Wikipedia

    en.wikipedia.org/wiki/Lift_slab_construction

    Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...

  7. 3D concrete printing - Wikipedia

    en.wikipedia.org/wiki/3D_concrete_printing

    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 ...

  8. Self-consolidating concrete - Wikipedia

    en.wikipedia.org/wiki/Self-consolidating_concrete

    Self-consolidating concrete or self-compacting concrete (SCC) [1] is a concrete mix which has a low yield stress, high deformability, good segregation resistance (prevents separation of particles in the mix), and moderate viscosity (necessary to ensure uniform suspension of solid particles during transportation, placement (without external compaction), and thereafter until the concrete sets).

  9. Rebar spacer - Wikipedia

    en.wikipedia.org/wiki/Rebar_spacer

    A concrete spacer with a plastic clip in use Concrete spacers in a precast element Diaphragm wall block on rebar for a Diaphragm wall. A rebar spacer is a short, rod-like device used to secure reinforcing steel bars, or rebar, within cast assemblies for reinforced concrete structures. The rebar spacers are fixed before the concrete is poured ...
