  2. Hollow-core slab - Wikipedia

    en.wikipedia.org/wiki/Hollow-core_slab

    Hollow-core slabs and wall elements without prestressed steel wire can be formed by extruders. The size of these elements will typically range in width from 600 to 2400 mm, in thickness from 150 to 500 mm, and can be delivered in lengths of up to 24 m. [1] The voids of the hollow core can be used as conduit for installations.

    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. Sandcrete - Wikipedia

    en.wikipedia.org/wiki/Sandcrete

    Soil cement and landcrete are similar materials but use other types of soil [1] and hydraform blocks which are compressed, stabilized, earth blocks. Sandcrete is usually used as hollow rectangular blocks similar to concrete masonry units, often 45 centimetres (18 in) wide, 15 centimetres (5.9 in) thick, and 30 centimetres (12 in) with hollows ...

  7. 3D concrete printing - Wikipedia

    en.wikipedia.org/wiki/3D_concrete_printing

    Particle sizes that are too large may block the nozzle of the 3D printer, while aggregates that are too small decrease the strength of the mix and can cause cracking. [8] A rule of thumb for mix design is that the maximum aggregate particle size should be less than 1/10 of the nozzle diameter to ensure smooth extrusion. [8]

  8. Hollow structural section - Wikipedia

    en.wikipedia.org/wiki/Hollow_structural_section

    A hollow structural section (HSS) is a type of metal profile with a hollow cross section. The term is used predominantly in the United States, or other countries which follow US construction or engineering terminology. HSS members can be circular, square, or rectangular sections, although other shapes such as elliptical are also available.

  9. Ecology block - Wikipedia

    en.wikipedia.org/wiki/Ecology_block

    Ecology blocks are manufactured using concrete left over from other construction processes. A cross-section of an eco-block typically measures 2 feet (61 cm) square, with block lengths ranging from 3 feet (91 cm) to 6 feet (180 cm). One block weighs between 1,800 pounds (820 kg) and 4,000 pounds (1,800 kg). [1]
