German technology Lightweight Sand Fly Ash ALC Panels AAC Block Production Line AAC Plant from Hongfa manufacturer
Autoclaved Aerated concrete AAC has been used all over the world .Firstly produced in terms of industrial means in sweden in 1923.It is a unique building concept , available in today's market with innumerable building advantages.
AAC (autoclaved aerated concrete ) blocks main raw materials are siliceous materials (sand ,fly ash and silicon tailings) and calcium materials (lime and cement)mixed with foaming agent ( aluminum powder).It is the product of light porous silicate though the following processes :raw materials batching,slurry processing ,powder preparation and storage,mixing and pouring ,hardening curing ,cutting and grouping , autoclaving, packaging ect. Because of large amount of well-distributed tiny pores after foaming,it is named autoclaved aerated concrete.
AAC type:in general ,it can be classified according to the types of raw materials ,based on the shape of aac products ,it can be divided into:AAC blocks and AAC panels ,ALC panels . It is a revolutionary material offering an unique combination of high durability and strength , low weight ,ecellent heat insulation,fire resistant , noise absorption,unprecedented build ability and superior ecological gree features.In china, AAC is one of the light wall materials which was popularized and applied at the earliest and most widely.
AAC block and ALC panel application
AAC is light weight concrete that is produced under special circumstances ,by adding aluminum paste which creates a porous shape into the mixture of cement,fly ash,water and limestone .AAC is very firm and the most durable construction materials that provides heat insulation by its porous texture,security against earthquakes through its lightweight structure , and safety sgainst fire by its non-flammable quality .AAC building products can be used for all applications including every type of masonry walls ,roofs and floors .AAC is preferred especially in many developed countries such as all EU countries ,USA, Japan <Russia,Australia,and all Gulf countries and kingdom of saudi arabia ,and most developing countries .
Advantages of the AAC blockS1. Sound proof
AAC wall has an excellent sound Transmission class (STC) ,rating of 44. Result: Virtually Soundproof Interiors
2. Thermal Insulation
It has highest thermal rating in the industry….R30! Thus provides well insulated interiors, keeping out warm air in summer and cold air in winters. AAC reduces Air conditioning cost by 30%.
3. Earthquake Resistant
Earthquake forces on structure are proportional to the weight of the building, hence AAC shows excellent resistant to earthquake forces. Regions of high seismic activity like Japan exclusively use AAC. It has been proven to withstand wind loads of category 5
4. Floor Space Area
Use of thinner blocks (6" instead of 9" exterior walls) because of its excellent water barrier & insulation properties leads to an increase in floor space area between 3-5%.
5. Cost saving
Being lightweight AAC drastically reduces the dead weight of building, resulting into reduction in steel (up to 27%) and cement (up to 20%) structural cost saving. Being 8 times the size of a clay brick, AAC wall construction involves 1/3 the joints, thus an overall mortar saving up to 66%.Its automatic manufacturing process gives AAC an exceptional dimensional accuracy & smooth surfaces, eliminating need of three-coat plaster walls and allows for a final 6 mm skim coat (putty/POP).
6. Fire Resistant
Best in class fire rating of 4 hours. The melting point of AAC is over 1600 ºc, more than twice the typical temperature in a
building fire of 650 ºc.
7. Pest Resistant Termites hate AAC!
Being made of inorganic minerals, it does not promote growth of molds.
8. Water Barrier
Its structure does not allow for capillary action making it impervious to water. Its water barrier properties are further enhanced by adding silicone based additives.Strength to weight ratio, higher than even M150 concrete and far exceeds the Indian Building code requirements.
9. Energy Efficient
AAC is 100% Green Building Material & is a walling material of choice in LEED certified buildings (ITC centre, the highest rated Green Building has been built using AAC).AAC is most energy & resource efficient in the sense that it uses least amount of energy & material per m³ of product. Unlike brick manufacturing process which uses previous top layer agricultural soil, AAC uses Fly Ash (65% of its weight), thus provides the most constructive solution to the nation's fly ash utilization pr
Equipment of Lightweight Sand Fly Ash ALC Panels AAC Block Production Line AAC Plant Blocks Making Machine Manufacturer from HongfaThe advantages from Hongfa Lightweight Sand Fly Ash ALC Panels AAC Block Production Line AAC Plant process:1. It can realize the mixed grinding to prepare the cementitious material and effectively improve the pouring stability; the flow-tube type pouring stirring can shorten the stirring time and greatly improve the uniformity of stirring.
2. Raw material processing can realize the hydrothermal ball milling process and improve the stability of fly ash and mortar.
3. Staggered batching process. The batching building is divided into two and staggered. It simplifies the layout of equipment and building structure, and meets the requirements of staff space and equipment layout.
4. Integrated layout technology, which arranges the batching, pouring, pre-cultivation, cutting, bottom removal, marshalling and other processes in the same workshop. Uses hydraulic lifting and conveying equipment to separate the walking guide from the main body of the workshop and reduce the height of the workshop. Layout, avoiding dead corners in the building, shortening the return path of waste water and waste slurry, reducing the moving space of operators and improving work efficiency.
Hongfa AAC production line includes:raw material preparation → mixing & pouring → molding → curing & cutting → steam generating
system → autoclaving → finished products upload & packing,
