Many people still have a vague concept of aerated bricks, as we are not in this industry, so we are relatively unfamiliar with them. In fact, the so-called aerated brick is a new type of environmentally friendly and energy-saving building material. Aerated bricks can be divided into non autoclaved aerated bricks and autoclaved aerated bricks due to their different production processes and required materials. Next, let's familiarize ourselves with the advantages and differences between non steamed aerated bricks and autoclaved aerated bricks?

Advantages of One Non Steaming Aerated Brick

1. Small bulk density reduces the weight of the building. The bulk density is generally between 300 and 300; 800kg/m3, able to float on the water surface, only 1/4 of solid clay bricks and 1/2 of hollow blocks, can reduce wall load by 50-60%, reduce building weight by 20-30%, and have fast construction speed, greatly reducing labor intensity and construction cost for workers.

2. Significant thermal insulation performance greatly reduces building energy consumption. Its thermal conductivity is 0.168w/(m.k), and its insulation effect is 4 times that of clay bricks and 3 times that of hollow blocks. It is warm in winter and cool in summer, greatly reducing air conditioning operation time and saving 30-50% of electricity consumption. It is the preferred wall material for achieving building energy efficiency.

3. Excellent sound absorption and insulation performance. The porous structure of the steam free aerated brick gives it good sound absorption and insulation performance. The sound insulation of the 240mm thick wall is 58dB, which can fully meet the sound insulation requirements of shared walls and households.

4. Good seismic resistance. Due to its lightweight, non steam aerated bricks greatly reduce the weight of the building and increase its seismic resistance by two levels compared to clay brick buildings.

5. High strength, good processability, and diverse specifications and sizes. Its strength is the same as that of autoclaved aerated blocks; Production does not require coarse aggregates, so it can be sawed, planed, glued, nailed, and processed as needed for easy decoration; There are various specifications and sizes of steam free aerated bricks that can meet various masonry needs.

Advantages of autoclaved aerated bricks

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

2. Lightweight; Autoclaved aerated bricks can reduce the weight of buildings, decrease the cross-sectional dimensions of structural components, lower the cost of foundations, and reduce the difficulty of constructing weak foundations.

3. Sound absorption and insulation; The interior of autoclaved aerated bricks is filled with small pores, which have good sound insulation effect. Different thicknesses can reduce noise by 30-50 decibels.

4. Insulation and heat preservation; Has good thermal insulation performance. Its thermal insulation is six times that of glass, seven times that of clay bricks, and ten times that of ordinary concrete blocks.

5. Fire resistant and flame-retardant; Autoclaved aerated bricks are inorganic substances that will never burn and will not produce harmful gases even at high temperatures. At the same time, the thermal conductivity of aerated concrete blocks is very low, which makes heat conduction slow, effectively resisting fires and protecting their structures from the impact of fires.

The difference between three types of autoclaved aerated bricks and autoclaved aerated bricks

1. Differences in raw materials; The raw materials for steam free aerated bricks are widely available, such as cement, fly ash, slag, slag, river sand, stone powder, etc. Any one of them can be used. Autoclaved aerated bricks require a power plant as a prerequisite, followed by the utilization of power plant fly ash and favorable conditions.

2 process differences; Non steaming blocks only need to be mixed, foamed, blended, and poured in one go, and can be naturally cured. The production process of autoclaved aerated bricks is complex, and the equipment investment is huge. It requires ball mills, large steel molds for pouring foam and static curing, large cutting machines for overall cutting, boiler steam curing rooms and operating equipment, which consume a lot of energy and require a large investment.

3 performance differences; The aperture of non steam aerated bricks is closed and independent, and does not absorb water. The pore size of autoclaved aerated bricks is open and has strong water absorption, so their insulation, heat insulation, and sound insulation are inferior to those of non autoclaved bricks.

In the mandatory clause 3.1.4 of the national standard GB 50574-2010 "Technical Code for Application of Wall Materials", it is clearly stipulated that "; Non autoclaved aerated concrete products should not be used for walls;.

Due to the lack of necessary curing processes, non autoclaved aerated concrete products have poor durability of the final product, which will pose hidden dangers to wall applications. Therefore, caution should be exercised when dealing with such products.

The above is an introduction to the advantages and differences between non steamed aerated bricks and autoclaved aerated bricks. We hope the above text can help you understand aerated bricks.
