German brick making machine manufacturers tell you the formula of retaining bricks!

Regarding German brick making machines, what materials can be used to make bricks? The formula of unburned retaining bricks is given to you!

The raw materials of unburned retaining bricks range widely, including sand, gravel, stone powder, cement, fly ash, slag, steel slag, coal gangue, ceramsite, perlite, construction waste, etc. At present, sand, gravel, stone powder and cement are generally used as raw materials. Fly ash, slag, slag, ceramsite, perlite, solid waste and other raw materials can also be used to make bricks, but soil or materials with high mud content cannot be used to make bricks. Buyers provide the formula themselves or purchase the manufacturer's brick machine. German brick making machine manufacturer Zenith provides the formula. Unburned brick formula 1. Fly ash brick: 30% fly ash, 30% slag, 30% saltpeter, 8-10% cement, 0.2% rock sand.

Can the German brick making machine make permeable bricks and hollow bricks?

Yes. German brick making machine manufacturer Quangong Zenit will design the required brick type for customers according to customer needs. Finally, as long as the corresponding mold is replaced on the retaining brick machine, various brick types can be produced.

How to solve the problem of the white surface of the newly made pavement bricks?

You can add a little water reducer or alkali inhibitor. It is mainly caused by the high alkali content in the raw materials (cement, mixing water, or sand). The silicate cement must be used with a higher grade. If you don’t want to add the above additives, you can consider adding a small amount of very fine fly ash.

Characteristics of German brick making equipment,

1. Sintered bricks destroy arable land, and the combustion of coal in production causes serious pollution to the atmospheric environment. German fully automatic retaining brick machines are energy-saving and environmentally friendly, which is the market development trend. 2. As long as you have 1-2 of fly ash, slag, coal gangue, slag, sand, stone powder, and construction waste in your local area, you can make bricks, and the raw materials are relatively cheap locally. 3. The strength of the bricks made exceeds the national standard, and has good durability, corrosion resistance and stability.
