Foam Concrete1) heat preservation sex: coefficient of thermal conductivity 0.135 rookie - for W / (m • k), thermal resistance of concrete for ordinary about 20 to 30 times.
2) lightweight sex: dry bulk density for 200-700kg/m3, equivalent to ordinary cement concrete 1/5 ~ 10 or so, can reduce the building integrally load.
3) integrity: but the spot with the main project construction, casting, without the need to stay closely combining border every seam and breathable tube.
4) low play damping foam concrete sexual: the porous make it has low elastic modulus, allowing it to impact load has good absorption and dispersion.
5) sound insulation sex: foamed concrete contain a lot of independent air bubble, and distributes uniformly, sound-absorbing capacity is 0.09 - the predictive, is ordinary concrete 5 times, have the function of effective sound insulation.
6) resistance: the compressive strength is 0.6-5.5 Mpa.
7) water resistance: cast-in-situ foam concrete water imbibition is lesser, relatively independent closed bubbles and good integrity, make its have certain waterproof properties.
8) durability: with the main body of the project life the same.
9) construction is simple: simply use cement foam machine can realize automation assignments, which can realize the vertical height 100 meters, long-distance transmission for 80-200m3 / workload workday.
10) production processing: foamed concrete can not only in factory in various products into production, but also can field construction, direct cast-in-situ into roofing, ground and wall body, and can make saw, dig, nail, drilling of processing.
11) environmental: for the ingredients needed for foam concrete cement and foaming agent, foaming agent for neutral, not including benzene, harmful material such as formaldehyde, to avoid the environmental pollution and fire hazard.
12) economic: comprehensive cost is low.

Concrete is one of the raw materials used in the construction industry. It is also one of the most historically important inventions of all time. Is to build by the Romans the Coliseum, is a proven material that has been used for centuries. Since then he has gone through a long process of continuous improvement.
There are many types of concrete available and the estimated amount of concrete produced worldwide each year about six million cubic meters. Technological advances have quite good permeable types of concrete such as high-strength concrete, asphalt concrete, sprayed concrete, SCC, etc., known
A type of concrete that has recently seen more public exposure called foam concrete. This type of concrete is very different from traditional types of concrete where the weight is generally 1:5 1/3rd of normal concrete.
Foam concrete is usually composed of cement, water and air bubbles trapped in the mixture. The air is usually has a tight control is a special type of foam is introduced into the mixture. This foam has a consistency like shaving foam and the air bubbles are so fine that they are virtually invisible to the naked eye.
More than other types of concrete, to make special arrangements, the raw materials for the production of aerated concrete and a bad mixture, the material on a much smaller force will have a mixture. A major advantage of porous concrete compared to ordinary types of concrete is that it requires no advanced way of healing. Everything to do what you can, properly adjusted, the joint air cure of about 4 to 7 days.
Foam concrete is perhaps the only type of concrete that can be used in the permafrost as the numerous applications of this technology proved successful in Canada.The high air content can affect the material like a sponge, so little can change their shape when the frost to prevent fractures.
Aerated concrete applications are almost unlimited. On many advantageous properties such as high flow without compaction, workability, resistance to freezing and thawing. These functions are only a very good choice in applications such as: reducing the burden of soils, the different types of road under the base charge, base plates for the isolation, the production of prefabricated insulating panels and much more.

Porous concrete and porous concrete are two very different materials, which are often confused. This article will focus on the presentation of why these two products, although similar to the surface actually two completely different technologies.
AAC was also known by its shorter name AAC invented in Europe in the 1920s to meet the needs of the construction industry after the war. A lightweight, prefabricated building that could be produced in large scale proved to be ideal for those times. The material provides a support structure, insulation and fire protection in a single layer.
AAC is composed usually of quartz sand, lime, cement, water and air entraining agent. The difference between ordinary concrete and AAC is that the total size of not more than 2.0 mm. This means that the gravel is not used in their manufacture. The air entraining agent is aluminum powder generally used in amounts generally less than 0.1% by volume.
By mixing the raw materials, various chemical reactions. First, the aluminum powder reacts with calcium chloride and water. This reaction leads to the formation of hydrogen gas which acts as an air entraining agent in the mixture. Since the reaction occurs, more gas is released, thereby increasing their volume, the mixture gradually. Ultimately, the amount of its volume can have up to 5 times increased, as the amount of aluminum powder.
This phase of the manufacturing process ends with the hydrogen replaced by air, and escapes into the atmosphere.
The second reaction occurs much later in the process. After the material is mixed and reaches its maximum volume, which is hard and cut into blocks with a wire. then placed in an autoclave chamber, where the second reaction takes place. At high temperature and pressure in the chamber of calcium hydroxide reacts with silica sand hardened the hydrate form of silica has high calcium crystal structure. This process can achieve up to 12 hours in which the pressure 12 bar, when temperatures can reach 180 degrees Celsius can. After this period, the system is ready for use in the workplace.
The technology for the production of aerated concrete used is very different from that used in the production of AAC block.The only similarity between the two processes are raw materials. In the case of aerated concrete in general are cement, water and a certain type of foam. This last component is the foam, what distinguishes the cost of producing this material, in addition to the very expensive production AAC.
The particular type of foam for the production of aerated concrete is required, a liquid concentrate called foaming agents. It is usually mixed with water to 2.5% to 5% and built into a foam generator for this purpose. The rate of expansion of the middle foam around 08.01 clock, which is the optimum for this application. The resulting foam has a density of only 50 grams per liter, or, in other words, 50 kg per cubic meter. In cement, water and foam mix, the result is a very fluid mix ratio.
The main advantage of AAC is that there are large investments, requires expensive to manufacture. In fact, usually made directly on the site with relatively simple devices, whereas AAC only be performed in facilities built.
