AAC as a building material has been industrially produced since the beginning of the 20th century. We are hoping to be able to produce more innovative and creative. AAC has been produced for more than 70 years, however, some disadvantages were found when it was introduced in the UK (where cavity wall with clay brick two-skin construction has been the norm). It is an ideal Class A fireproof construction material. A standard 8-by-8-by-24 inch unit weighs about 33 pounds; U-shaped bond beam or lintel blocks are available in thicknesses of 8, 10, and 12 inches. Because of its low density, our products not only feature low raw material consumption, but also reduce carbon emissions during transportation and installation process. Autoclaved Aerated Concrete blocks (AAC Blocks), which are also commonly known as Aerated Lightweight Concrete blocks (ALC Blocks) are common masonry blocks used in construction of a wall. Company Introduction: Ecotrend (Cambodia) New Building Material Development Co., Ltd. Is a Chinese-invested enterprise established in the Kingdom of Cambodia, specializing in the development, manufacture, and export of eco-friendly, energy-efficient new building materials --- autoclaved aerated concrete (autoclaved lightweight concrete) products (known as AAC or ALC products). ALC panels can be used with reinforcing bar according to the design to meet a variety of load-bearing requirements. During this steam pressure hardening process, when the temperature reaches 190C (374F) and the pressure reaches 800 to 1,200kPa (8.0 to 12.0bar; 120 to 170psi), quartz sand reacts with calcium hydroxide to form calcium silicate hydrate, which gives AAC its high strength and other unique properties. Due to its lower density, high-rise buildings constructed using AAC require less steel and concrete for structural members. This creates an eco-friendly building, with a calming, quiet interior. Long lasting: The life of this material is extended because it is not affected by harsh climates or extreme weather changes. There is no need to use structural post, beam and other auxiliary components so that wall loading is decreased and building cost is reduced as well. Web Designed by, Sound Insulation: STC Test (Sound Transmission Class). Also known as autoclaved cellular concrete(ACC) blocks,autoclaved lightweight concrete(ALC) blocks,gasbeton, gas concrete, and cellular concrete, Autoclaved aerated concrete (AAC) blocks is a lightweight, precasted foam concrete block produced by combining various raw materials such as cement, sand, fly ash and other chemicals heated in high temperature and compressed using pressure autoclave processes to provide superior structural strength, insulation, fire resistance and mold resistance for both internal and external construction usage.

As if the security and weather resistance werent enough reason to select AAC for his own home, the developer anticipates saving 35 percent on his utility bills and 65 percent on his insurance premiums. Depending on its density, up to 80% of the volume of an AAC block is air. An expansion agent like aluminum powder is added and the fluid mixture is cast into a large billet. It is a porous silicate plate made for high performance. The practical need for AAC. Your delivery dates are very fast, much faster than we expected, and you are very good at communicating. Upon the introduction of aluminum as en expansion agent, air bubbles are introduced throughout the material, generating a low-density lightweight . Resource efficiency gives it lower environmental impact in all phases of its life cycle, from the processing of raw materials to the disposal of waste. He didnt want to attach a siding product, preferring instead direct-applied finishes: gypsum plaster for the interior and stucco for the exterior. It not only reduces the construction difficultly, but also is conducive to the quality of the project and shortens project period. AAC is a concrete-based material used for both interior and exterior construction. USED. It is due to the small thermal conductivity, heat is migrated slowly. AAC floor systems bear directly on top of AAC walls. There is a decrease of 50% of greenhouse gas emissions. It was first used in a project based in Shanghai more than 70 years ago and remains intact until now. Special, large diameter. Lighter, more fire-resistant, and a better insulator, autoclaved aerated concrete caught on in the rest of the world ages ago. For structural needs, grouted, reinforced cells and beams are placed within the wall section. Low Basic Investment ACI Committee 213R-03 [27] has recommended an equation to obtain thermal conductivity ( ) of structural LWC related with its dry unit weight ( w) as follows: (1) = 0.0864 e 0.00125 w. With more than 29 years experience and being the biggest manufacturer in China at present.All . Furring strips should be employed if back ventilation of the siding material is desirable. ALC internal panels are the thinnest among those with the same capacity in sound insulation and fire protection. 2022 Portland Cement Association. Some years ago, when architect Alice Dodson selected AAC to build her own home, it was partly for health and environmental reasons. Autoclaved aerated concrete (AAC) is a lightweight, precast, foam concrete building material suitable for producing concrete masonry unit (CMU) like blocks. FortisLite Panel is a durable aut Read More The brand Autoclaved aerated concrete (AAC) is concrete that has been manufactured to contain closed air pockets. Lightweight concrete Lightweight concretes can either be lightweight aggregate concrete, foamed concrete or autoclaved aerated concrete (AAC). Autoclaved Lightweight Concrete (ALC) Blocks Market Forecast by regions, type and application, with sales and revenue, from 2022 to 2028. SMBKZ has positioned autoclaved lightweight concrete (ALC) panels as a key material in catering to wide-ranging demand in the construction industry, and is responding to various construction requirements based on the networks and credit creditworthiness of Mitsui & Co., Ltd., Sumitomo Corporation, and Marubeni Corporation. So developers turned to a concrete system to help meet their needs for delivering a quality projectin this case, a strong, quiet, four-story structure near a heavily traveled highway. As the slurry reacts with the expansion agent to generate air bubbles, the mixture expands. Porous structure gives superior fire resistance. From "Yxhults nghrdade Gasbetong" later became the first registered building materials brand in the world: Ytong. After production, the panels also need to be tested through sampling to review whether the structure performance meets the load requirements. One of its advantages is quick and easy installation, because the material can be routed, sanded, or cut to size on-site using standard power tools with carbon steel cutters. After the autoclaving process, the material is ready for immediate use on the construction site. Autoclaved aerated concrete (AAC) is a lightweight, precast, foam concrete building material suitable for producing concrete masonry unit (CMU) like blocks. It can be categorized into external wall panels, partition panels (internal panels), roof panels and floor panels according to the usage. A long-time sustainability advocate, she was also already following Bau-biologie. Non autoclaved lightweight aerated concrete recipe you can find here http://www.pioner-group.com/concrete/ Foamed concrete, also called cellular light weight. [3][4], Other names for the product include autoclaved cellular concrete (ACC), autoclaved concrete, cellular concrete, porous concrete, Aircrete, Thermalite, Hebel Block, Aercon,[5] Starken, Gasbeton, Airbeton, Siporex, and Ytong. Because of the relatively low temperature used, AAC blocks are not considered to be a fired brick but a lightweight concrete masonry unit. A continuous bond beam is created at the top, either with plywood and AAC material or with bond beam block. The porous AAC structure comes from being "leavened" with aluminum. The air bubbles are uniformly distributed and are retained in the matrix on setting, hardening, and . The simplicity of AAC, he says, allows him, in one step, to construct a structural wall that is insulated, resistant to termites, and ready for finishing. ALC Panels are lightweight and easy-processed, which may ease labour intensity. Panels are set into a layer of thin-bed mortar and vertical rebar is attached to dowels extending up from the floor before the adjacent panel is placed. Due to less weight the blocks can be handled easily. Autoclaved aerated concrete (AAC) is a type of precast concrete with an expansion agent that rises the mixture, similar to yeast in bread dough. As with other concrete products, the carbon footprint of manufacturing and transporting can be high, and should be considered when comparing to other building products. [1][2], AAC products may be used for both interior and exterior construction, and may be painted or coated with a stucco or plaster compound to guard against the elements, or covered with siding materials such as veneer brick or vinyl siding. Tongue and groove blocks are available from some manufacturers, and these connect to adjacent units without mortar at vertical edges. [citation needed]. [10] Production of aerated concrete requires less energy than for all other masonry products, thereby reducing the use of fossil fuels and associated carbon dioxide (CO2) emissions. New production plants are being built in Australia, Bahrain, China, Eastern Europe, India and the United States. Autoclaved aerated concrete (AAC), a form of cellular concrete, is a low-density cementitious product of calcium silicate hydrates in which the low density is obtained by the formation of macroscopic air bubbles, mainly by chemical reactions within the mass during the liquid or plastic phase. Invented in the mid-1920s, AAC simultaneously provides structure, insulation, and fire- and mold-resistance. Openings and odd angles are cut with a handsaw or bandsaw. If it has to be shipped, its light weight is advantageous. In consistently cold climates, the savings may be somewhat less because this material has lower thermal mass than other types of concrete. What is autoclaved aerated concrete blocks? Originally Ytong autoclaved aerated concrete in Sweden was produced with alum shale, whose combustible carbon content was beneficial in the production process. Autoclaved aerated concrete (AAC) is a lightweight, precast, foam concrete building material suitable for the production of concrete masonry unit (CMU) blocks composed of quartz sand, calcined gypsum, lime, cement, water, and aluminum powder, AAC products are cured under heat and pressure in an autoclave. AAC is a lightweight material composed of silica sand, gypsum, lime and cement. AAC was perfected in the mid-1920s by the Swedish architect and inventor Dr. Johan Axel Eriksson,[6][7] working with Professor Henrik Kreger at the Royal Institute of Technology.
