1. AAC introduction:
AAC (Autoclave Aerated Concrete) is a new type building material where the raw materials are siliceous materials (fly-ash, sand, slag), calcareous materials (lime, cement and gypsum) and Aluminium powder.
AAC product has been widely used in industrial and civil construction. AAC product can be divided into AAC block and AAC plate.
AAC Block is short for Autoclaved Aerated Concrete Block. which is also called ALC Block. It is lightweight and loadbearing and made from silica sand, cement, lime and gypsum.
The block may be well used as both external wall (exterior wall) and internal wall (interior wall). It has been widely used for various buildings, such as villas, apartments, schools, factories, shopping mall, hospitals, etc... We have been exporting the blocks to many foreign countrie for some years with good reputation.
Properties of Tongde AAC Block:
- Lightweight
- High Strength
- Sound Insultion
- Heat Insulation
-Thermal insulation
- Anti-vibration
- Fireproofing
- Load-bearing
- No radioactivity

3. Process flow
(1) raw materials: sand, cement, fly ash, slag, gypsum, shale, most of industrial waste can be used as block raw materials, which improves a lot on environment.
(2), Measuring, batching and casting section
Slurry, cement agents, gypsum and aluminum go into high-speed stirring mixer after automatic measuring respectively, and then bubbles inside green body will be sorted out by vibration rods. The whole system is full-automatically controlled by PLC to guarantee the high efficiency and precision of procedure running.
(3)Static curing and Cutting
Stable and still curing can avoid damage to internal structure when the gas is and expanding inside the green block. High efficient and fluent cutting machine and table tilt machine are the key parts to the hexahedral cutting.
(4) Autoclaving and Final Product Process
Green body gets final strength and performance via autoclaving. our newly developed separating and packing system can not only promote qualification rate but also solve the difficulty in separating blocks and wall panels at the same time.4. AAC BLOCK PARAMETERS:
1. Light Weight: 300~800kg/m3
2. High Intensity: 3.5~10.0Mpa
3. Good Thermal Insulation Property: 0.1~0.20W/(m · k)
4. Keeping Temperature, Heat Resistant, Fireproof
5. Good Sound Insulation
6. Earthquake Proof

Professional in Construction machinery, our main products are brick machine and concrete pump, as well as building materials AAC block; We have exported our products to many countries from Africa, Asia, Oceania, South America. We have SGS certificate; Our superiority is good quality machine with very resonable price, and best service as we can.
Basically, we introduce our main products as following:
Brick making machine: We can provide small mobile blcok machine, e semi-automatic, fully automatic brick, paver brick, curbstone making machines.
Concrete pump: Electrcial and diesel engine types are the two main types, comptetive price and nice solution are our advantanges.
AAC block: This is new popular products, it is widely USD in high buildings, but because of small product cost, the mainly marekt is China nearby countries, which needs a small ship cost.
Raytone aims to provide customer an acceptable and cost effective project solution as one-stop buying service. We are highly appraised by client because of patient service and nice machine quality.
Raytone plan to make a group of various building machine and building materials, under the convienice of logistic city and all kinds of big markets in our city, we make our own warehouse, packing and logo, we do customized delivery; We aim to meet the clients who want to buy different buidling materials like door, window, tiles.
