Can anyone tell us about hollow bricks and clay bricks?

First, the raw materials are different.

1. Hollow bricks: The raw materials for manufacturing are clay and cinder ash, and the specifications are 390 190 190mm.

2. Small concrete hollow blocks: they are made of ordinary concrete materials such as cement, sand, and stone.

Second, the characteristics are different.

1. Hollow brick: light weight, high strength, good heat preservation, sound insulation and noise reduction. Environmentally friendly and pollution-free, it is an ideal filling material for frame structure buildings. The quality indicators of the brick are in line with the national standards after inspection.

2. Small concrete hollow block: light weight, good thermal performance, good seismic performance, convenient masonry, good wall flatness, high construction efficiency, etc. Not only can they be used for non-load-bearing walls, but also for load-bearing walls of multi-storey buildings with blocks of higher strength grades.

It has good social and economic benefits to reduce the production cost of blocks and reduce environmental pollution.

Third, the scope of use is different.

1. Hollow brick: It is the main wall material commonly used in the construction industry.

2. Concrete small hollow block row cover annihilation: suitable for block houses in industrial and civil buildings, especially for load-bearing walls and frame structure filling walls of multi-storey buildings.

Judging from the name of cement hollow bricks, we can know what kind of bricks cement hollow bricks are. According to the classification of the main raw materials for the production of hollow bricks, hollow bricks are mainly divided into clay hollow bricks, shale hollow bricks and cement hollow bricks. Among them, cement hollow brick is a hollow brick made of cement as the main raw material, after raw material treatment, molding, sintering and other feeding processes.

Generally, the total area of holes in cement hollow bricks accounts for more than 15% of the brick area.

Cement hollow bricks have been very popular after appearing in the construction market, but in 2011, after a ** incident in Yunnan, whether cement hollow bricks can be used in construction began to be widely questioned. The reason is that in the grade ** that occurred in Yunnan, many people were killed by the collapse of houses built of cement hollow bricks. After the earthquake, Yunnan first banned the use of hollow bricks because of the potential safety hazards in the construction of cement hollow bricks, and Qingdao, Shandong Province, also banned the use of hollow bricks in building construction.

Since then, cement hollow bricks have been banned from being used in various places, what is the reason for this? Should the use of cement hollow bricks be banned? Let's take a look at the characteristics of cement hollow bricks.

The reason why cement hollow bricks have been widely used after entering the market. The reason is that cement hollow bricks have the advantages of light weight, high strength, good thermal insulation, good sound insulation and noise reduction. Due to the light weight and high strength of hollow bricks, their use in construction will not cause heavy pressure on the building wall, thus greatly reducing the probability of the wallboard being cracked by heavy pressure.

In addition, the use of cement hollow bricks in the construction can reduce the pressure of the wall on the ground, so that the air pressure in the wall is the same as the air pressure outside, and then reduce the probability of building cracking to a certain extent. In addition, due to the holes in the brick body of the hollow brick, the sound insulation effect is better than that of the solid brick, which reduces the noise impact to a certain extent. Another point is that cement hollow bricks are relatively solid bricks, which have the advantages of environmental protection and pollution-free, and are ideal filling materials for frame structure buildings.

However, hollow bricks have a fatal shortcoming, which is also the reason why cement hollow bricks have been stopped in various places - that is, the poor seismic performance of hollow bricks.

So can we use hollow bricks in our buildings? Construction experts said that in the construction process of residential buildings and other buildings, the main load-bearing wall should be poured with cement or solid bricks; Hollow bricks can be used for other non-load-bearing walls; Non-residential buildings such as fences can use Sorachifan grinding bricks.

Hello, I'm glad to answer for you: can soil make hollow bricks A, pro: No, fly ash, shale, etc. are the main raw materials.

Clay cannot be used in the production of hollow bricks, and the raw materials need to be processed and molded, and finally sintered. Hollow bricks are mainly made of fly ash and shale as the main materials, and the hole area of hollow bricks is more than 15%, compared with solid bricks, raw materials can be saved and weight is reduced, and the intensity of construction will also be reduced during construction, the weight of the overall building will be light, the number of floors of the building can be heightened, and the project cost can be reduced. Hollow brick is a common building material, as long as the construction method is scientific and reasonable, there will be no danger, and the scientific requirements for use are very high, and the quality will have limited standards.
