Autoclaved aerated concrete blocks What are the differences from concrete bricks

The wall materials used in the construction market before were mainly red bricks (clay bricks). At present, the state restricts the use of solid clay bricks as filling materials for frame structures in urban construction, and prohibits the use of solid bricks with strength grade below MU10 in buildings with more than 5 floors. 　　

1、 Autoclave Aerated concrete block performance

1. Light weight: As a building material, it can reduce the self weight of the building and greatly reduce the comprehensive cost of the building. 　　

2. Fire prevention: most of the main raw materials are inorganic materials, so they have good fire resistance and do not emit harmful gases in case of fire. 　　

3. Sound insulation: due to its unique porous structure, it has certain sound absorption capacity. 　　

4. Thermal insulation: due to the large number of pores and micropores inside the material, it has good thermal insulation performance. 　　

10. Economy: green, environmental protection and energy saving.

2、 Autoclaved aerated concrete block is a kind of block produced by means of high-temperature autoclave equipment process. Its advantage is that closed holes can be formed inside the concrete, so that the concrete is lighter and heat insulated. In fact, concrete brick is a special kind of aerated brick. Its material performance and hole structure are similar to those of aerated brick, but there are some differences between them. As for which one is more suitable for you to buy, you should first look at the analysis. 　　

1. From the perspective of fine structure characteristics

As we all know, foamed cement is a product that is connected by countless closed holes and has the advantages of sound insulation, heat insulation and heat preservation. Autoclaved aerated concrete blocks are the products that promote the cement slurry to become honeycomb from the gas, showing the shape of connecting holes. That is to say, from the perspective of detail structure, the concrete brick is not as effective as the aerated light brick in terms of sound insulation and moisture resistance. 　　

2. From the realized density

According to the survey results, the current density of concrete bricks is basically below 500kg/m3, while autoclaved aerated concrete blocks can be lower than this density. 　　

3. From the perspective of foaming means

You should know that the traditional concrete brick is foamed by chemical means, while the autoclaved aerated concrete block is completed by more flexible means. The details are as follows: use the high-pressure air pump to inflate, as long as the closed pores formed by the concrete are met, it is qualified. It can be seen that its foaming method is slightly better.
