Many people are still very vague about the concept of aerated brick. After all, we are not engaged in this industry, so we are all strangers. In fact, the so-called aerated brick is a new building material with environmental protection and energy saving. Aerated bricks can be divided into non-steaming aerated bricks and autoclaved aerated bricks because of their different manufacturing processes and required materials. Let's get familiar with the advantages and differences between non-steaming aerated brick and autoclaved aerated brick.

一  Advantages of a steam-free aerated brick

1, The bulk density is small, reducing the building weight. The bulk density is generally 300— 800kg/m3 can float on the water, which is only 1/4 of that of solid clay brick and 1/2 of that of hollow block. It can reduce the wall load by 50-60%, the weight of the building by 20-30%, the construction speed is fast, and the labor intensity of workers and the construction cost are greatly reduced.

2, Significant thermal insulation performance, greatly reducing building energy consumption. Its thermal conductivity is 0.168w/(m.k), and its thermal insulation effect is four times that of clay brick and three times that of hollow block. It is warm in winter and cool in summer, which greatly reduces the running time of air conditioning and saves 30-50% power consumption, and is the first choice for building energy saving.

3, Excellent sound absorption and sound insulation performance. The porous structure of non-steaming aerated brick makes it have good sound absorption and sound insulation performance, and the sound insulation capacity of 240mm thick wall is 58dB, which can completely meet the sound insulation requirements of households with common walls.

4. Good earthquake resistance. Due to the light weight of autoclaved aerated brick, the self-weight of the building is greatly reduced, which is two seismic levels higher than that of clay brick building.

5. High strength, good machinability and various specifications and sizes. Its strength is the same as that of autoclaved aerated block; Coarse aggregate is not used in production, so it can be sawed, planed, glued and nailed, and processed at will as needed, which is convenient for decoration; Non-steaming aerated brick has a variety of specifications and sizes, which can meet various masonry needs.

二  Advantages of autoclaved aerated brick

1. Machinable; Like wood, aerated concrete products can be sawed, drilled, nailed and ground easily.

2. Lightweight; Autoclaved aerated brick can reduce the weight of buildings, reduce the cross-sectional size of structural members, reduce the cost of foundation and reduce the construction difficulty of soft foundation.

3. Sound absorption and sound insulation; The autoclaved aerated brick is filled with tiny pores, which has good sound insulation effect, and the noise can be reduced by 30~50 decibels depending on its thickness.

4, Heat preservation, heat insulation; It has good thermal insulation performance. Its thermal insulation is six times that of glass, seven times that of clay brick and ten times that of ordinary concrete block.

5, Fire resistance, flame retardant; Autoclaved aerated brick is an inorganic substance, which will never burn and will not produce harmful gas even at high temperature. At the same time, the thermal conductivity of aerated concrete block is very small, which makes the thermal conductivity slow, which can effectively resist the fire and protect its structure from the fire.

三 Third, the difference between non-autoclaved aerated brick and autoclaved aerated brick

1 Raw material difference; Non-steaming aerated brick has a wide range of raw materials, such as cement, fly ash, slag, slag, river sand, stone powder and so on. Autoclaved aerated brick should have a power plant as a prerequisite, and then use the fly ash and favorable conditions of power plant.

2 Process differences; Steam-free blocks only need to be stirred, foamed, mixed and poured at one time and naturally cured. The production process of autoclaved aerated brick is complex, and the equipment investment is huge, which requires ball mill, large steel mold pouring and foaming for rest, large cutting machine for overall cutting, boiler steam curing room and operating equipment, which consumes a lot of energy and investment.

3 Performance difference; The pore size of non-steaming aerated brick is closed and independent and does not absorb water. Autoclaved aerated brick has an open pore size and strong water absorption, so its thermal insulation and sound insulation are not as good as those of non-steaming block.

Article 3.1.4 of the national standard GB 50574-2010 "Application System of Wall Materials-Technical Specification" clearly stipulates “ Non-autoclaved aerated concrete products should not be used for walls ” .

Due to the lack of necessary curing technology, the durability of the final product of non-autoclaved aerated concrete products is poor, which will bring hidden dangers to wall application. Therefore, we should be cautious about such products.

The above is the introduction of the advantages and differences between non-steaming aerated brick and autoclaved aerated brick. I hope the above words can make you know something about aerated brick.
