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.

About block and brick building 
admin , 17:09 , Concrete blocks and bricks , Comments(4) , Trackbacks(0) , Reads(602) , Via Original
Traditional brick and block houses remain the most popular form of self building with around 70% of self builders choosing this traditional build method.
A wet brick and block build is constructed with a block built internal skin and cavity followed by a brick external facing, remain the preferred building method of self-builders. According to the Traditional Housing Bureau (THB), an organisation that promotes brick and block building techniques, around 70 per cent choose this method to construct their property.
Heated discussions over the speed of brick and block construction will be around for years to come - it is often argued that the speed of construction is close between traditional methods and timber frames. This may well be the case if you've started trying to build and not yet ordered a timber frame, but timber if you plan to start once your frame is ready - as most do - a timber frame house will be water tight as much as four to six weeks sooner than a brick and block build.
Changes to thermal efficiency were introduced in April 2002, toughening up the building regulation requirements - an area where timber frame excels but this does not mean that brick and block building has had its day!
Thermal Performance
The solid mass of a brick and block self build allows the absorption of heat, which is radiated into the house. This creates a more stable temperature meaning less heat will be required at night.
Tests have shown brick and block built houses to maintain a temperature between 5°C - 8°C higher than lightweight structures.
Sound Insulation
Further to the thermal performance regulation changes, sound insulation specifications have been increased. It is widely accepted that mass stops noise in the simplest terms. Block work clearly provides a lot more mass over plasterboard and studwork partitions - when plastered the block work provides around 50 per cent greater sound insulation.
Superior sound insulation is provided by concrete floors over that offered by wooden floors, with a comparative reduction of around 47-52dB compared to 30-38dB of a timber floor.
Of course, these increased building specifications are rarely for the benefit of the self builders pocket, but brick and block has the advantage in these stakes. The cost of building either brick and block, or timber frame is now very close.
The interesting and perhaps less obvious advantage is down to the staged payments of a brick and block build. Timber frames have to be paid in full upfront whereas a self builder using brick and block can pay in several installments as and when more bricks are required. This is handy if you are relying on a mortgage that makes stage payments, rather a lump sum - though you must of course ensure your can complete each stage with the bricks you've bought!

1.Sound proof
AAC wall has an excellent sound Transmission class (STC) ,rating of 44. Result: Virtually Soundproof Interiors!
2.Thermal Insulation
It has highest thermal rating in the industry….R30! Thus provides well insulated interiors, keeping out warm air in summer and cold air in winters.AAC reduces Air conditioning cost by 30%.
3.Earthquake Resistant
Earthquake forces on structure are proportional to the weight of the building, hence AAC shows excellent resistant to earthquake forces. Regions of high seismic activity like Japan exclusively use AAC blocks. It has been proven to withstand wind loads of category 5 tropical storms.
4.Floor Space Area
Use of thinner blocks (6" instead of 9" exterior walls) because of its excellent water barrier & insulation properties leads to an increase in floor space area between 3-5%.
5.Cost saving
Being lightweight AAC drastically reduces the dead weight of building, resulting into reduction in steel (up to 27%) and cement (up to 20%) structural cost saving.Being 8 times the size of a clay brick, AAC wall construction involves 1/3 the joints, thus an overall mortar saving up to 66%.
Its automatic manufacturing process gives AAC an exceptional dimensional accuracy & smooth surfaces, eliminating need of three-coat plaster walls and allows for a final 6 mm skim coat (putty/POP).
6.Fire Resistant
Best in class fire rating of 4 hours. The melting point of AAC is over 1600 ºc, more than twice the typical temperature in a building fire of 650 ºc.
7.Pest ResistantTermites hate AAC! Being made of inorganic minerals, it does not promote growth of molds.
8.Water Barrier
Its structure does not allow for capillary action making it impervious to water. Its water barrier properties are further enhanced by adding silicone based additives.
9.High Strength
High pressure steam curing autoclaving process gives AAC unmatchable strength to weight ratio, higher than even M150 concrete and far exceeds the Indian Building code requirements.
10.Energy Efficient
AAC is 100% Green Building Material & is a walling material of choice in LEED certified buildings (ITC centre, the highest rated Green Building has been built using AAC).AAC is most energy & resource efficient in the sense that it uses least amount of energy & material per m³ of product.Unlike brick manufacturing process which uses previous toplayer agricultural soil, AAC uses FlyAsh (65% of its weight), thus provides the most constructive solution to the nation’s flyash utilization problem.
