Raw Materials:
- Cement: The main binding agent in concrete blocks.
- Aggregates: Fine and coarse materials such as sand, gravel, or crushed stone.
- Sands: The sands filling in all the gap of the blocks to make it stronger.
- Additives (optional): Chemicals used to enhance certain properties of the blocks.
- Water: Provides hydration for the cement.
-
Mixing:
- All the raw materials(Aggregates, cement and sands) are combined in the appropriate proportions.
- Water is added gradually while mixing to achieve the desired consistency.
- Mixing can be done with our JS or JQ concrete mixer.
-
Molding:
- The mixed concrete is poured into molds, which have done heat treatment.
- The molds are available in various shapes and sizes, depending on the desired block dimensions.
- Vibrators may be used to remove air bubbles and ensure uniformity.
- Usually for bigger machine like QT6-15 full automatic block making machine, it will be 4 motors for vibration to make the blocks stronger.
-
-
Blocks removing:
- Once the blocks have sufficiently cured and gained strength, they are removed from the pallets.(about 24hours)
- Care should be taken to prevent any damage to the blocks during removing.
-
Curing:
- The blocks need to be cured to gain strength and durability.
- The curing process typically involves keeping the blocks in a controlled environment with adequate moisture and temperature.
- Curing can be done by sprinkling water, covering with plastic sheets, or using a curing house.
-
Drying and Stacking:
- The demolded blocks are left to dry further in a well-ventilated area.
- Once completely dry, the blocks are stacked for storage or transportation.
-
Quality Control:
- Random samples of the produced blocks are tested for strength, dimensions, and other quality parameters.
- Any blocks that do not meet the required standards are rejected.
It's important to note that the specific details of the process may vary depending on factors such as the type of concrete block, production scale, and equipment used.
