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.
An ecology block, also known as an eco-block or ecoblock, is a type of recycled concrete block used to make retaining walls. 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 ...
Palette stacked autoclaved aerated concrete blocks. Autoclaved aerated concrete (AAC) is a lightweight, prefabricated concrete building material. Developed initially in the mid-1920s, it has expanded into widespread use. [citation needed] It is most suitable for producing a lightweight or most cost-effective alternative to traditional concrete ...
Strengths might exceed the ASTM standard for concrete blocks (1,900 pounds per square inch (13,000 kPa)) in some instances. In India, the observed compressive strength and flexural strength of CSEB at 28 days of aging with 9% cement stabilization has been observed to be 3.2 MPa (464 psi) and 1 MPa (145 psi) respectively.

A standard 8-inch CMU block is exactly equal to three courses of brick. [3] A bond (or bonding) pattern) is the arrangement of several courses of brickwork. [2] The corners of a masonry wall are built first, then the spaces between them are filled by the remaining courses. [4]
Panel khrushchevka in Tomsk. Khrushchevkas (Russian: хрущёвка, romanized: khrushchyovka, IPA: [xrʊˈɕːɵfkə]) are a type of low-cost, concrete-paneled or brick three- to five-storied apartment buildings (and apartments in these buildings) which were designed and constructed in the Soviet Union since the early 1960s (when their namesake, Nikita Khrushchev, was leader of the Soviet ...
ICF walls are constructed one row at a time, usually starting at the corners and working toward the middle of the walls. End blocks are then cut to fit so as to waste the least material possible. As the wall rises, blocks are staggered to avoid long vertical seams that can weaken the polystyrene formwork. [16]
A further benefit is that nails can be driven through the cement into the subfloor without it chipping. [8] The cost of gypsum concrete is comparable to regular concrete, ranging from $1.75 per square foot to $6.00 per square foot. [12] Regular concrete ranges from $2.50 to $4.50 per square foot. [13]
