What is Aerated Concrete?

Autoclaved Aerated Concrete (AAC) is a building material with outstanding thermal insulation,high loadbaring capacity at low weight and good workability.
Aerated Concrete is a well-proven material for almost 80 years and this in all climatic zones.Aerated Concrete is a high tech Calcium-Silicate-Hydrate produced out of Cao (contained in quicklime and cement),out of SiO2(contained in sand or PFA=Pulverized Fuel Ash ),anhydrite(gypsum),water and a trace of aluminium power(as aeration agent).
The raw materials are precisely dosed,mixed,poured into large moulds to form a "cake". The cake is pre-cured in climatized pre-curing chambers,cut to blocks or panels,steam cured in autoclaves at a temperature of 190°C(374°F).During the autoclaving process calcium silicate hydrate is formed.Finally the AAC is palletized.

Autoclaved Aerated Concrete Brick Machine-Autoclave

Description:

The length of the kettle body, the gauge size inside the kettle and the opening form of the kettle door can be manufactured according to the requirements of users.

USES and Features:

Autoclave is one of the indispensable equipment in the production line of aerated concrete block. Large container equipment is used for autoclaved curing of construction products such as lime sand brick, fly ash brick, aerated concrete block, new lightweight wall material, concrete pipe pile, etc. After steam raising, the products can obtain high strength.

Application:
The cut concrete blocks must be placed into the concrete curing autoclave for autoclaving in order to ensure the AAC blocks achieve a certain hardness.

Concrete curing autoclaves are used for autoclave curing of concrete blocks, and thus allowing the concrete block to complete hydrothermal synthesis and obtain different mechanical properties. The working pressure of the concrete curing autoclave is 1.3MPa～1.6MPa, and the working temperature of concrete curing autoclave is 191℃～201 ℃.

Autoclaving Time:
The concrete blocks need to go through several stages for complete autoclaving. This includes:

Before Autoclaving: 30min

Vacuum Pumping: 30min

Temperature Rise and Pressure Rise: 90min

Constant Temperature and Constant Pressure: 480min

Temperature Reduction and Pressure Reduction: 90min

After Autoclaving: 30min

Parts:
With a durable structure and reliable safety, the concrete curing autoclave is composed of the autoclave body, autoclave lid, orbit, pressure gauge and safety valve.

Formerly known as Wuxi SANKON Automation Equipment Co., Ltd., Jiangsu SANKON Building Materials Technology Co. is an enterprise specializing in the research and development and production of a complete range of autoclaved aerated concrete (AAC) machines and AAC production lines. Since 2007, we have introduced a number of new types of building materials equipment. We have been actively analyzing cutting-edge technology from all over the world and have formed a professional technology team focused on the development of new and exciting processing equipment.

In July, 2014, Jiangsu SANKON Building Materials Technology Co., Ltd. was officially founded in Chuanjiang Town, Xinbei District, Changzhou City, Jiangsu Province, with a factory covering 44700 square meters. Today, we have more than 200 employees. The AAC machines manufactured by SANKON has been exported to a wide range of countries, like Russia, India, Iran, Saudi Arabia, Malaysia, Indonesia, Thailand, Vietnam, the United Arab Emirates, and more.

Professionalism
SANKON has always focused on the design and production of high efficiency AAC machines, resulting in the accumulation of valuable experience and engineering techniques.

Our technical team is made up of experts with more than 20 years of experience in the AAC industry. They are professionals with expertise in project design, production processes, and detail control. Some of them worked for the China AAC Institute before they came to SANKON, then they focused all of their efforts into the AAC industry.

With this excellent technical team, we are able to offer clients solutions and equipment that meets all relevant production quality requirements, as well as help building materials manufacturers maximize their economic returns.

Autonomous Production
With an annual production capacity of more than 9 thousand tons of equipment and workshops covering about 25 thousand square meters, SANKON is able to autonomously complete machining, painting, assembling, and testing processes. Parts like metal bodies, hydraulic pressure stations, electric control cabinets and so on are all produced by SANKON.

We are able to offer complete sets of equipment for AAC production line. SANKON is also able to precisely control the function and quality of each piece of equipment to meet customer needs.

Continuous Innovation
Based on German technology, we developed the AAC production lines with additional specifications. At the same time, we have been consistently improving our equipment offerings to meet the various needs of customers.

For instance, the blade used in the pouring mixer was updated from a conventional single blade to a cross blade and flow diversion blade, and now the high speed double blade design results in higher stirring efficiency. The driving method is updated from belt drive to variable frequency drive as it is now directly connected. Besides, each connecting piece is fine finished by us.

Currently, SANKON has obtained 19 patents for components applied in our AAC cutter, mold, transfer cart for AAC block pre-curing and batching automatic control system.

Market Prospect
For many years, SANKON has been focusing on the research and development of AAC machines, as well as collaborating with AAC product manufacturers and providing AAC production line solutions to these AAC product manufacturers. We have served hundreds of clients in the building materials industry and have achieved wide praise.

In recent years, we have developed quickly and achieved production value of tens of millions of dollars.
