WHAT IS AAC

Autoclaved aerated concrete is made of siliceous materials (sand, fly ash or tailings, etc.) and calcareous materials (lime and cement) with aluminum powder paste and other materials, through the production process of raw material preparation, batching and pouring, reinforcement section (for panel production), pre-curing and aerating, demoulding and cutting, grouping before autoclaving, high-pressure steam autoclaving and packing.

AAC ADVANTAGES

Structural Performance

AAC is extremely strong and durable despite its lightweight. Its excellent mechanical properties make it the construction material of choice for earthquake zones.

Technical Performance

AAC is classified as a non-combustible building material. It is both resistant to fire up to 1200°C and, unlike other construction materials, heatresistant.

Environmental Production

No raw materials and water/steam are wasted during production, less energy consumption than for all other masonry products, thereby reducing emissions of CO2. No toxic gases are created in the production process.

High Resource Efficiency

AAC demands relatively small amounts of raw materials per m3 of product, and up to a fifth as much as other construction products. Industrial by-products can be used for producing AAC.

AAC APPLICATION CASE

HISTORY OF AAC INDUSTRY

Origin of Autoclaved Aerated Concrete

· AAC was first developed in Sweden in 1920s, when an architect Axel Eriksson first combined the conventional concrete mixture of cement, lime, water, and sand with a small amount of aluminum powder.

· In 1929, the world's first AAC plant was built in Sweden, then "Ytong" & "Siporex" two production process systems were gradually formed in northern Europe and several highend equipment suppliers appeared, and then AAC was gradually developed to the whole Europe and even all over the world.
AAC Initial Trial Production Period in China

· In 1958-1962, the Chinese Academy of Building Sciences organized experts to study and trial produce AAC.
· In 1965, the first AAC plant in China was built with Siporex technology, then China AAC industry entered a slow development period.

· In 1992, the State Council issued the notice on accelerating the innovation of wall materials and promoting energy-saving buildings, China entered the new wall materials era, then AAC block gradually replaced solid clay brick to be the main wall material.
AAC Industry Emerging Period in China

· In 1995, Nanjing JT imported the second-hand equipment of Wehrhahn. Mr. Xu Shunwu, who was the engineer of Wuhan Building Materials Research Institute, upgraded the equipment to produce AAC smoothly.
· In 1996, China Xujian imported second-hand cutting machines of Siporex plant from Japan. Mr. Xu Shunwu was responsible for the overall design of auxiliary machines.

· In 2003, Yinghai Industrial Group imported the second-hand equipment of Wehrhahn from South Korea, and Mr. Xu Shunwu upgraded the automation level of the plant.
AAC Localized Production Period in China

· In 2004, Mr. Xu Shunwu established Wuhan New Suremaker Building Material Technology Development Co., Ltd. in Wuhan.
· In 2006, Wuhan Suremaker provided the auxiliary machines for Changxing Ytong Co., Ltd. established by Xella group in Zhejiang province.

· In 2008, Wuhu Suremaker Industrial Co., Ltd. was established in Anhui, and provided the auxiliary machines for Xella Tianjin AAC plant.
AAC Localized Production Period in China

· In 2011, Wuhu Suremaker built China's first fully-automatic AAC panel plant in Shandong province. In the same year, Suremaker production lines was exported to Indonesia and other foreign countries.
· In 2012, KEDA cooperated with SUREMAKER to build the KEDA SUREMAKER brand, then the company changed from an equipment manufacturer to a holistic AAC plant solution supplier.
AAC Rapid Development Period in China

· Attended the 6th & 7th International conference on AAC to give speech on behalf of China AAC industry and joined European AAC Association.
· Up to now, the AAC plants supplied by KEDA SUREMAKER have been installed all over 30 provinces in China and exported to Asia, Middle East, Europe, South America & other area of the world.
