2. 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.

3. Masonry - Wikipedia

   en.wikipedia.org/wiki/Masonry

   Masonry walls have an endothermic effect of its hydrates, as in chemically bound water, unbound moisture from the concrete block, and the poured concrete if the hollow cores inside the blocks are filled. Masonry can withstand temperatures up to 1,000 °F (538 °C) and it can withstand direct exposure to fire for up to 4 hours.

4. Properties of concrete - Wikipedia

   en.wikipedia.org/wiki/Properties_of_concrete

   Wired.com reported on 13 April 2007 that a team from the University of Tehran, competing in a contest sponsored by the American Concrete Institute, demonstrated several blocks of concretes with abnormally high compressive strengths between 340 and 410 MPa (49,000 and 59,000 psi) at 28 days. [3] The blocks appeared to use an aggregate of steel ...

5. 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]

6. Precast concrete - Wikipedia

   en.wikipedia.org/wiki/Precast_concrete

   Precast concrete molds can be made of timber, steel, plastic, rubber, fiberglass, or other synthetic materials, with each giving a unique finish. [3] In addition, many surface finishes for the four precast wall panel types – sandwich, plastered sandwich, inner layer and cladding panels – are available, including those creating the looks of ...

7. Lunarcrete - Wikipedia

   en.wikipedia.org/wiki/Lunarcrete

   Two solutions to this problem have been proposed: premixing the aggregate and the cement and then using a steam injection process to add the water, or the use of a pressurized concrete fabrication plant that produces pre-cast concrete blocks. [2] [9] Lunarcrete shares the same lack of tensile strength as terrestrial concrete.

9. 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, eco-friendly, [1] suitable for producing concrete-like blocks. It is composed of quartz sand, calcined gypsum, lime, portland cement, water and aluminium powder. [2] [3] AAC products are cured ...
