Recruit factory directors and craftsmen of aerated brick factory

The difference between lightweight brick concrete and aerated concrete is the object of investigation by many customers. Now, the difference is explained as follows:

1. Detailed structural features: Foamed cement is a product with thermal insulation, sound insulation and thermal insulation, which is connected by countless closed holes. However, aerated concrete is honeycomb-shaped, because gas is emitted from the inside, and its holes are communication holes. Therefore, from the detailed structure, aerated concrete block does not have the excellent performance of sound insulation, heat insulation and moisture resistance of light brick concrete block.

2. Smaller density can be achieved: According to the survey, the density of aerated blocks on the market at present is above 500kg/m3, while the density of lightweight brick concrete blocks can be less than 500kg.

3. Foaming method is more flexible: traditional aerated concrete only adopts chemical foaming, while lightweight brick concrete adopts more flexible foaming method. In addition to foaming with foaming machine and foaming agent, it can also be inflated with high-pressure air pump. As long as the purpose of forming closed pores in concrete can be achieved, the foaming method is not limited.

4. More diversified curing technology: due to the variety of lightweight brick concrete, the diversity of oxidation technology is needed, and natural curing, steam curing or other curing methods can be adopted according to different cementing materials.

5. There are many kinds of molds: in order to reduce investment, increase product types and increase the added value of lightweight brick concrete, small molds, combined molds and artistic molds made of various materials can be used. It can also be poured directly on site without mold.

6. Production investment cost: The investment of aerated concrete with an annual output of 50,000 cubic meters is 3 to 5 times that of foamed concrete. The investment scale of lightweight brick concrete can be large or small, from several million to less than100000.

The quantity of clay sintered brick (240× 1 15×53mm) is generally 75 to 100. However, the baking-free block brick is designed strictly according to the standard above 100, and its strength completely reaches the national standard, and the highest compressive strength can reach 18Mpa. Due to the reaction between fly ash and pozzolan of other materials, calcium silicate hydrate and calcium aluminate gel are generated to fill the pores, enhance the cohesive force, promote the long-term growth of strength, and have good durability, corrosion resistance and stability. Both theory and practice have proved that its later strength is increasing and its service life is longer than that of clay brick QQ:253944736.
