Concrete Block:
A concrete block is a block made of concrete. To raise the quality of the blocks you need to apply vibration and force to make the mortar as compressed as possible. A concrete block is a general name and includes different types of blocks. Below you can see some examples of concrete blocks.
* Hollow concrete blocks with different shapes and sizes.
* Solid concrete blocks with different shapes and sizes.
* Paving blocks with different shapes, sizes, and colors.
* Hollow floor blocks

In all the items you can see concrete included but and you may ask what concrete is. Concrete is formed with aggregates, water, and Portland cement which is usually in the form of powder. There are different standards for the mixture ratio of the 3 items. Also, admixtures are available to add extra features to the concrete.

Note that there is a difference between additive and admixture. Additives are added to cement during manufacturing to get new properties for cement but admixtures are added to concrete while mixing to get new features. Depending on your country you can use different aggregates as well, most common aggregates are limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.

Concrete Block Manufacturing Process:
The concrete block manufacturing process has different steps based on the system you are producing them. The concrete block manufacturing process can be manual, semiautomatic, automatic, and full-automatic depending on your demand, country, and budget. Below you can find about Fully Automatic Block Manufacturing Process, because we’re using this method for our manufacturing.

Full-automatic concrete block manufacturing process:
The difference between automatic and full-automatic methods is that in the automatic method you need an operator to operate the machine but in a Full-automatic concrete block machine, the machine operates automatically. This design is suitable for developed countries where labor cost is high and the land is also expensive.

Concrete Block Machine:
These machines are also called “interlocking brick machines”. There are different types of concrete block machines available in the market. Some of them are mobile and some of them are stationary. In this project, we’re using mobile machine, named “Lorev – BL1020A-Lunga” (Made in Italy)..

Batching Plant Mixer:
In this project, we’re using Chines made Batching plant HZ35, having mixer JS750 with three Hoopers and Cement Silo. It will be used to mix the aggregates (Sand, Cement, Water & Crescent). It will include one control room where the operator can mix aggregate as per requirement from Control Room.

How To Produce Concrete Blocks:
To produce concrete blocks, we need to provide the plant with raw materials like aggregate, water, and port land cement. Then we need to mix them together to have a homogenous creamy mixture with JS750 Mixer. There are different mixture ratios available based on country standards and aggregate availability. Also based on the machine choice, we’re doing it automatically.

After we prepare the mortar it is time to feed it to the machine. Usually, it is done by conveyor belts. Then the machine takes care of the rest. the mortar is first poured into the machine aggregate hopper. After mortar is prepared, we’re using a Fork lifter with Concrete bucket, to be filled by mixer. And then we’ll put this mortar to Mobile machine mold.

When the mold is filled with mortar it is time for the hydraulic press to do the compressing. The vibration also helps the hydraulic system to compress it in the best possible way.

After the concrete blocks are shaped over the surface, the machine leads the pallet toward the output of the machine. After completing one cycle of block making, the machine automatically move from its position and then start a new cycle.

Vehicles To be Used for Production:
* Wheel Loader
* Fork Lifter (having Concrete bucket)
* Fork Lifter (having Block Clamp)
* Tipper (for bring Raw Material)
* Block Crane (for delivery of Blocks)

Concrete Block Manufacturing Daily Capacity and Annualy:
Each day consists of three shifts and each shift is eight hours. It is easier to discuss the capacity in each shift so there won't be any confusion. Initially we’re going to start with single shift of 8 hours. Depending on the concrete block you are producing, the capacity of your concrete block manufacturing plant is different. For the hollow blocks and solid blocks, the capacity is described in numbers. The concrete block machines offered by Lorev can produce 1400-1800 pieces of standard blocks (19 cm width x 39 cm length x 19 cm height) in each hour. And as per day capacity, one shift will generate minimum 11,200 pieces and maximum 14,400 pieces.

Area will be 1850 sqm and also there will be 10 production lines 70 meter long and annually we can produce 51,84000 blocks in only one shift.
