• Of glasses: They are the most usual model. Sometimes it is used with the holes horizontally to allow a little vision and give way to the air with the outside.
• Multicamera: The internal holes of this model are compartmentalized. These types of blocks are usually used when you want to build a wall with a single sheet.

• Load: They are usually more solid and are used for walls that have structural functions.

Finishes

In addition, here we show you a classification of the blocks according to their finish or design:

• Normal block to coat
  • Solid block
  • Column block
• Block for reinforced wall
  • Block type H
  • U-block
• Face block
  • Smooth block
  • Split block
  • Diamond Tip Block
  • Lattices
• Hydroblock
  • Multi-chamber anti-humidity blocks

Fabrication process

A common question among people is: How are concrete blocks made?

We tell you that for any of the methods of manufacturing cement blocks the stages are basically the same, below we show you a list with the steps of the process:

Mixing

1. Gravel and sand are stored outdoors and transported to the storage containers at the plant via a conveyor belt.
2. Once production begins, the required units of Portland cement, gravel, and sand are transported to a weighing feeder where the required quantities of each material are measured.

1. The dry materials are mixed for several minutes.
2. After the dry materials have been mixed, a low portion of water is added to the mixer.
3. The concrete is mixed for a time of 6 to 8 minutes.

Molding

1. Since the concrete load has been mixed, it is poured into a bucket conveyor and transported to a raised hopper.
2. From the hopper, the concrete is transferred to another hopper that is located at the top of the blocking machine . Since the material is in the block machine the concrete is pressed down to form the molds.
3. With the mix in the mold, the compaction / vibrate phase of the concrete begins to begin to form the blocks.
4. The already compacted blocks are pushed down and out of the molds onto a flat steel platform. The blocks and platforms are moved out of the block machine to a chain conveyor.

Cured

1. The block pads are transported to an automatic stacker that places them on a curing rack. When the rack is complete, they are taken to the curing oven (the most common is a low pressure steam oven).
2. In the oven, the blocks are kept for 1 to 3 hours at room temperature so that the material hardens slightly. Subsequently, steam is gradually introduced to raise the temperature to a maximum speed of 16 ° C per hour.
3. When the proper cure temperature is reached (66 to 74 ° C), the steam is shut off and the blocks are allowed to soak in the hot, humid air for a time range of 12 to 18 hours.
4. The blocks are then dried by consuming all the humid air and further raising the oven temperature. The entire curing process takes approximately 24 hours.

Storage

1. The cured block stacks are removed from the oven and the block pallets are unstacked to be placed on a chain conveyor. The blocks are then pressed out of the steel pallets and the pallets are forwarded to the blocking machine to be filled by a new group of molded blocks.
2. The removed blocks go through a bucket that aligns each block and are then carried out with a forklift and stored.

Price of concrete blocks

The cost of concrete blocks varies greatly depending on the country you are in and the design and size you choose. But to give you an idea of ​​the approximate cost, here is a list of some blocks.
