Molded and Cut Wall Excellent Integrity Precast Concrete Wall Construction Concrete AAC Panel

Ecotrend manufactures autoclaved aerated concrete (AAC) or aerated lightweight concrete (ALC) block and panel, it is a composite of cement, lime, and silica sand. Besides, ALC panel uses bidirectional welded steel mesh (reinforcing bar) ,which has been treated with a superior rust preventive liquid and cured with high-temperature, high-pressure steam. A porous silicate board is manufactured for high performance of anti-permeability and sound insulation. It can be divided into external wall panels, partition panels (internal wall panels), floor panels and roof slabs according to the purpose.

AAC blocks and ALC panels are widely used in various projects,such as commercial, factory, and residential buildings etc. The product has the characteristics of convenient installation, wide application range, and high construction accuracy; meanwhile, it can greatly improve the usage performance of the building, and reduce the cost of construction. 

Autoclaved aerated concrete (shorted as AAC) is a kind of lightweight precast concrete, it was invented in the mid-1920s and has developed for around 100 years. Since 1980, the production of AAC Blocks continues to increase globally and it is increasingly used by developers, architects, builders around the world, especially for prefabricated building, this is in line with the development trend of the construction industry.

Ecotrend (Cambodia) New Building Materials 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). 

Ecotrend was founded in June 2019, which is located at Sihanouk Ville Special Economic Zone, Cambodia. The company occupies land area of about 25000 square meters; and total investment of more than 14 million dollars. 

Ecotrend has introduced world's advanced aerated concrete production line to produce AAC blocks and ALC panels (ALC panel belongs to prefabricated building materials). The company has annual production capacity of 400,000 cubic meters, which is the largest and only ALC panel manufacturing enterprise with green prefabricated building material in Cambodia. Since it only about 20-minutes driving from Sihanouk Ville Port, thus, Ecotrend is endowed with unique geographical advantage for exporting. 

• What is Autoclaved Aerated Concrete?

  Autoclaved Aerated Concrete (AAC) is a lightweight concrete that is formed into blocks and panels for a wide range of loadbearing and non-loadbearing construction applications. It is manufactured from silica sand, cement, recycled material, lime, gypsum, aluminium paste and aerating agents. It is moulded, cut and steam pressure cured in an autoclave before being packed, ready for transport.

• Is Autoclaved Aerated Concrete a new building material?

  Aerated Concrete Autoclaved (AAC) is an amazingly innovative building material that has been used in Europe for more than 80 years and in the US for more than 15 years.  

• Where has Autoclaved Aerated Concrete been used?

  It can be used ranging from low rise industrial/commercial developments to high rise offices or medium density residential buildings. 

• Is Autoclaved Aerated Concrete a load bearing material?

  The intensity of pressure for cube is more than 4mpa. The load bearing capacity for one point is more than 1200N. The rebars within AAC panels are made according to computer calculating force. As a non-loadbearing cladding, AAC panels can be used under circumstances of pressure.

• What are the benefits of Autoclaved Aerated Concrete over other building materials?

  a. Cost effective - lightweight panels allow for reduced structural components and smaller lifting equipment.

  b. Excellent thermal resistance performance.

  c. Acoustic performance - effective sound transmission barrier between external and internal environments of the building.

  d. Excellent fire rating properties.

  e. No wet trades - less mess and a cleaner, safer work area.

  f. Less wastage - significantly reduced waste as panels can be custom-made to length requirements.

  g. Fewer waste bins and less crane movements.h. Design flexibility - panels can be easily cut and routed to suit design requirements.

  i. Panel lengths up to 6 metres. 

  j. Strong, secure and durable with corrosion protected steel-reinforced panels.
