Concrete blocks are the fundamental components of the construction industry. Concrete is the most prominent raw material used for making concrete blocks along with powdered Portland cement, water, sand, and gravel. The mixture of all these materials produces a light gray colored block with fine surface texture.
The production process of concrete blogs
The manufacturing process of concrete blocks consist of four steps mixing, molding, curing and cubing. Some concrete block production line suppliers only manufacture concrete blocks. While normally, production lines produce a wide variety of precast concrete products, including bricks, flat paver stones, and decorative landscaping pieces etc. Almost all concrete blocks manufacturing process involves this four stages.
Mixing
Sand and gravel and cement are mixed well by mechanical means and three of the contents of blocks pour into a stationary mixer where they are blended for several minutes. After these material is mixed properly small amount of water is then added to the mixture and incase the plants is located in extreme places then water is passed through the heater and chillers to regulate the temperature and color pigments are also added at the same time. After all this, the main content concrete is included into the mixture.
Molding
The mixture of concrete block is poured into the molds and compacted by the weight of upper molds. The compaction may be assisted by hydraulic pressure cylinders acting on the mold head. The compacted blocks are pulled out of mold onto the conveyor and pass under a rotating brush to remove the excess material.
Curing
The whole curing cycle takes about 24 hours and it the process of sending molded blocks to steam kiln for the solidification process.
Cubing
Further, these blocks are passed through cube which aligns the blocks and then stacks them into different sizes of cubes. After that the concrete blocks are sent to storage.
