  2. Reinforced concrete - Wikipedia

    en.wikipedia.org/wiki/Reinforced_concrete

    Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of steel, polymers or alternate composite material in conjunction with rebar or not.

  3. Rebar - Wikipedia

    en.wikipedia.org/wiki/Rebar

    Rebar (short for reinforcing bar), known when massed as reinforcing steel or steel reinforcement, [ 1 ] is a tension device added to concrete to form reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension. Concrete is strong under compression, but has low tensile strength.

  4. Concrete block - Wikipedia

    en.wikipedia.org/wiki/Concrete_block

    A pallet of "8-inch" concrete blocks An interior wall of painted concrete blocks Concrete masonry blocks A building constructed with concrete masonry blocks. A concrete block, also known as a cinder block in North American English, breeze block in British English, concrete masonry unit (CMU), or by various other terms, is a standard-size rectangular block used in building construction.

  5. Concrete slab - Wikipedia

    en.wikipedia.org/wiki/Concrete_slab

    A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving (see below). [ 1 ][ 2 ] In many ...

  6. Properties of concrete - Wikipedia

    en.wikipedia.org/wiki/Properties_of_concrete

    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] Reinforced concrete is the most common form of concrete. The reinforcement is often steel rebar (mesh, spiral, bars and other forms). Structural fibers of various materials are ...

  7. Masonry - Wikipedia

    en.wikipedia.org/wiki/Masonry

    Masonry is the craft of building a structure with brick, stone, or similar material, including mortar plastering which are often laid in, bound, and pasted together by mortar. The term masonry can also refer to the building units (stone, brick, etc.) themselves. The common materials of masonry construction are bricks and building stone, rocks ...

  8. Reinforced concrete column - Wikipedia

    en.wikipedia.org/wiki/Reinforced_Concrete_Column

    Reinforced concrete column. A reinforced concrete column is a structural member designed to carry compressive loads, composed of concrete with an embedded steel frame to provide reinforcement. For design purposes, the columns are separated into two categories: short columns and slender columns.

  9. Shear wall - Wikipedia

    en.wikipedia.org/wiki/Shear_wall

    Concrete shear walls are reinforced with both horizontal and vertical reinforcement (Figure 4). A reinforcement ratio is defined as the ratio of the gross concrete area for a section taken orthogonal to the reinforcement. Construction codes of practice define maximum and minimum amounts of reinforcement as well as the detailing of steel bars.
