Aerated brick: that is, autoclaved aerated concrete block, is a lightweight and porous wall material, due to its light weight, large volume, due to the internal porous structure and has good sound insulation, thermal insulation function, widely used in the wall material of frame structure. It is an ideal self-insulating wall material.
The disadvantage is that the load-bearing performance is not as good as that of other wall materials. However, most of the private houses in rural areas are brick-concrete structures, so aerated bricks are not suitable for rural areas.
Steam-free aerated bricks: Listen to this name should be the same as aerated bricks, in the form of physical gas, which belongs to the manufacturer's marketing gimmick, because the investment threshold of aerated bricks is very high, it is produced. It is estimated that the investment threshold for this material will be lower than that of aerated bricks.
How well it performs is unknown.
Unburned bricks: aggregate + cement + sand.
Solid pressed concrete bricks, in terms of investment cost, energy conservation and environmental protection are still relatively good, but after all, the products produced are bricks, in the unburned bricks I saw, it really can't be called bricks, the quality is heavy, and the durability is not enough. This is also the reason why the state has not been able to ban the rural areas for so many years, and it is not advisable to ignore product quality for the sake of energy conservation and environmental protection.

After many users saw the promotion information of autoclav-free aerated block equipment and autoclaved aerated concrete equipment on the Internet, they found that the autoclave-free ** was much lower than the autoclaved one.
Autoclaved aerated block introduction: autoclaved aerated block is mainly made of fly ash and sand as the main raw materials, river sand, lime, cement as ingredients, aluminum paste as the gassing agent (the use of chemical reaction foaming), through raw material grinding, ingredient stirring, pouring gas, static stop cutting, autoclaved curing into a new type of green self-insulating wall material. This kind of wall material has the characteristics of light weight, high strength, durability, thermal insulation, sound insulation, fire prevention, impermeability, and good anchoring performance, and is widely used in construction as the filling and thermal insulation material of the envelope structure, and has been widely valued by all countries in the world, and has become the preferred building material for the promotion and development of many countries.
Introduction of autoclav-free aerated block: the autoclave-free aerated block is also mainly based on cement, fly ash, slag, sand, stone powder with low soil content and tailings sand, etc. as the main raw materials, using gas making agent and reinforcing agent to polymerize cement, fly ash, sand and other materials, through physical aeration, the use of special equipment and mold forming, no need for autoclaving curing. Autoclav-free aerated block has a high cost, high waste rate and low cost, and the brick products produced can be used as non-load-bearing bricks for high-rise frames, and can also be used as lightweight concrete cast-in-situ for roofing, walls, walls, floor heating and other thermal insulation fields.
Because it is produced by the natural curing of cement, it does not need to be heated and autoclaved, so it is called autoclaving-free aerated block.
The difference between autoclaved aerated block and autoclav-free aerated block: the biggest difference between the two types of equipment is that the autoclave aerated block production line is complex, with autoclave and boiler heavy-duty autoclave equipment, while the autoclave-free aerated block production line does not; The cost of autoclaved aerated block is lower than that of autoclav-free aerated block (the amount of cement is larger, and the cost is higher); The performance of the finished product of the autoclaved aerated block is different from that of the autoclaved aerated block: the freeze-thaw and compressive strength of the lightweight brick produced by the autoclave-free aerated block equipment can not meet the national standard requirements for lightweight bricks at the same time, under normal circumstances, the freeze-thaw property needs to be 9 times to reach the standard, and the freeze-thaw performance of the autoclaved aerated block is good, if the freeze-thaw does not meet the standard, the wall will fall off.
In addition, in terms of compressive strength, the state regards the compressive strength of wall materials as the standard, and the compressive strength of the autoclaved aerated block can reach, and the compressive strength of the autoclaving-free compressive strength is around. It is recommended that users invest in autoclaved aerated block equipment.

1) Advantages of autoclaving curing process.
In the autoclaved state, water vapor can quickly penetrate into the inside of the ceramsite and the inside of the raw material particles with the help of pressure, and the silica and aluminum oxide in the raw materials are dissolved quickly. The reaction between these leachables and calcium hydroxide is also carried out quickly, and the hydration reaction is carried out more thoroughly, and the silicate and aluminate crystals are generated more and coarse, so that the strength of the ceramsite is improved and the performance is improved. Compared with various curing processes, the ceramsite produced by autoclaving curing has the best performance and quality under the same formula and raw materials, and if the same strength and performance as other processes are maintained, the cement used in autoclaving curing can be reduced by 20% to 30%.
Therefore, autoclaved curing ceramsite has a quality advantage, which is incomparable with other curing processes.
High production efficiency, short curing time due to the autoclaved curing reaction is carried out quickly, can greatly shorten the curing time, the general curing of 8 12L can be, at the same time the product out of the kettle is the product, no need to do other treatment. A set of autoclave can be produced continuously in three shifts, so the efficiency of autoclave curing is the highest, and the product leaves the factory the fastest.
Occupy a small site, because the autoclave curing is only carried out in the autoclave, the curing site only needs a few hundred square meters, which is equivalent to one-tenth of the natural curing, and the finished ceramsite of autoclave curing does not need to be stacked in the factory, and the autoclave can be sold, so the finished product pile occupies a relatively small site area. Autoclaved curing has the smallest footprint among all kinds of curing, so it is especially suitable for enterprises with small areas.
The cost of curing is not high, although there is some energy consumption for autoclaved curing, but because it can use less cement or no cement, the cost of ceramsite is not very high, only slightly higher than natural curing, and lower than calcined products. Therefore, it still has a big advantage in terms of cost. This is of great significance for improving the efficiency of enterprises.
2) Disadvantages of autoclaving process.
The investment in equipment is large, and the biggest disadvantage of autoclaving maintenance is that the equipment investment is large. Generally, more than three autoclaves are needed, each autoclave is 150,000 250,000 yuan, plus hundreds of thousands of yuan for boilers, tens of thousands of yuan for steaming and maintenance vehicles, and nearly 1 million yuan for equipment investment.
There is a certain amount of energy consumption, which does not conform to the principle of energy conservation Autoclaved ceramsite must have a certain amount of energy consumption, mainly because the coal burning of the boiler is large. It is obviously more energy-intensive than natural conservation.
There is a certain amount of air pollution, and coal-fired boilers are used for autoclaved maintenance, and a certain amount of carbon dioxide is released when coal is burned.
High-pressure operation has certain safety problemsCompared with other processes, the autoclave process is operated under high pressure, which is prone to safety problems. If the management is not good or the operation is improper, it will cause potential safety hazards, so autoclave maintenance has high requirements for safe operation and safety management.
