  2. Air entrainment - Wikipedia

    en.wikipedia.org/wiki/Air_entrainment

    Air entrainment in concrete is the intentional creation of tiny air bubbles in a batch by adding an air entraining agent during mixing. A form of surfactant (a surface-active substance that in the instance reduces the surface tension between water and solids) it allows bubbles of a desired size to form.

  3. 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, or concrete masonry unit (CMU), or by various other terms, is a standard-size rectangular block used in building construction.

  4. Cast-in-place concrete - Wikipedia

    en.wikipedia.org/wiki/Cast-in-place_concrete

    Cast-in-place concrete or Cast-in-situ concrete is a technology of construction of buildings where walls and slabs of the buildings are cast at the site in formwork. [1] This differs from precast concrete technology where slabs are cast elsewhere and then brought to the construction site and assembled. [ 2 ]

  5. Autoclaved aerated concrete - Wikipedia

    en.wikipedia.org/wiki/Autoclaved_aerated_concrete

    Palette stacked autoclaved aerated concrete blocks. Autoclaved aerated concrete (AAC) is a lightweight, precast, cellular concrete building material. Developed initially in the mid-1920s, it has expanded into widespread use. It is most suitable for producing concrete-like blocks [1] and as an eco-friendly alternative to such.

  6. Scoria - Wikipedia

    en.wikipedia.org/wiki/Scoria

    Another major use of cinders is in manufacture of concrete and cinder blocks. Scoria is also used in the construction of flexible, long-lasting roadbeds, due to its high strength and high angles of internal friction. Because of its good insulating properties, such roadbeds protect the ground beneath them from frost heave and heat deformation. [7]

  7. Rustproofing - Wikipedia

    en.wikipedia.org/wiki/Rustproofing

    The loss of electrons in paint is also claimed to be the cause of “paint oxidisation” and the electronic system is also supposed to protect the paint. [4] However, there is no peer reviewed scientific testing and validation supporting the use of these devices and corrosion control professionals find they do not work.

  8. Cavity wall - Wikipedia

    en.wikipedia.org/wiki/Cavity_wall

    Components on a concrete masonry unit and brick cavity wall. A cavity wall is composed of two masonry walls separated by an air space. The outer wall is made of brick and faces the outside of the building structure. [6] The inner wall may be constructed of masonry units such as concrete block, structural clay, brick or reinforced concrete. [6]

  9. 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).
