  2. Cement board - Wikipedia

    en.wikipedia.org/wiki/Cement_board

    This 516 inch (7.9 mm) thick cement board is designed as an underlayment for tile floors. These are 3-by-5-foot (91 by 152 cm) sheets. These are 3-by-5-foot (91 by 152 cm) sheets. A cement board is a combination of cement and reinforcing fibers formed into sheets, of varying thickness that are typically used as a tile backing board. [ 1 ]

  3. Precast concrete lifting anchor system - Wikipedia

    en.wikipedia.org/wiki/Precast_concrete_lifting...

    F = W x Ksl x Ks x 0.5 = 64.8 x 1.16 x 1.2 x 0.5 = 45.1 kN; Anchor capacity for initial lift F/n = 23 kN per anchor during initial lift (n = 2 lifting anchors) Transport loads in the yard and on-site Suction due to casting bed adhesion is not considered, as the calculation takes into account the lifting device dynamic coefficient.

  4. Anchorage in reinforced concrete - Wikipedia

    en.wikipedia.org/wiki/Anchorage_in_Reinforced...

    Conventionally the term concrete refers only to concrete that is reinforced with iron or steel. However, other materials are often used to reinforce concrete e.g. organic and inorganic fibres, composites in different forms. While compared to its compressive strength, concrete is weak in tension. Thus adding reinforcement increases the strength ...

  5. Anchor plate - Wikipedia

    en.wikipedia.org/wiki/Anchor_plate

    An anchor plate, floor plate [1] or wall washer is a large plate or washer connected to a tie rod or bolt. Anchor plates are used on exterior walls of masonry buildings, for structural reinforcement against lateral bowing. Anchor plates are made of cast iron, sometimes wrought iron or steel, and are often made in a decorative style. [2]

  6. Anchor bolt - Wikipedia

    en.wikipedia.org/wiki/Anchor_bolt

    Column-to-foundation connection [1] Anchor bolts are used to connect structural and non-structural elements to concrete. [2] The connection can be made by a variety of different components: anchor bolts (also named fasteners), steel plates, or stiffeners. Anchor bolts transfer different types of load: tension forces and shear forces. [3]

  7. Screw piles - Wikipedia

    en.wikipedia.org/wiki/Screw_piles

    Helical anchors consist of an extendable steel shaft with helical bearing plates. Piles or piers refer to strong base elements that withstand or transfer vertical/horizontal loads. Anchors are piles utilised only in tension applications like restraining wall tiebacks or vertical ground anchors made to resist overturning forces.

  8. Concrete block - Wikipedia

    en.wikipedia.org/wiki/Concrete_block

    The compressive strength of concrete blocks and masonry walls varies from approximately 3.4 to 34.5 MPa (500–5,000 psi) based on the type of concrete used to manufacture the unit, stacking orientation, the type of mortar used to build the wall, and whether it is a load-bearing partition or not, among other factors. [18] [19] [20] [21]

  9. Reinforced concrete - Wikipedia

    en.wikipedia.org/wiki/Reinforced_concrete

    (2) The thermal expansion coefficients of concrete and steel are so close (1.0 × 10 −5 to 1.5 × 10 −5 for concrete and 1.2 × 10 −5 for steel) that the thermal stress-induced damage to the bond between the two components can be prevented. (3) Concrete can protect the embedded steel from corrosion and high-temperature induced softening.
