Leca Block and Leca Block Making Machine

Leca block or light weight block is a combination of fine aggregates, cement and water. In order to keep the lightness of the block, the fine grained material is removed from the concrete to produce a higher porosity than the semi-light concrete.

wetpress

The difference between wet press and vibrating press concrete machine

The wetpress machine is used to produce a variety of high density products such as curbstone, paver and related products.
The products made by a linear wet press, have unique characteristics like high compressive strength, abrasion resistance.
In addition to this, these products have quality parameters which are not possible in another process. The moulds of different types of products can be specifically developed according to the specific requirements of the customer.
The vacuum system attached to the top of the machine, has created an option for removable filters, which ensures the output of water (without cement) through the product during the pressing function.
Other advantages:
Small products with high endurance
The best level to finish the production
Practical for a small amount
The disadvantages of wet press curbstones:
1. Over time and in freezing situation, Cracks are appeared because of using wet material.
The disadvantages of wet press concrete machines:
1. It is not economical based on number of production
2. Low productivity
A) The maximum number of curbstones are 400 in single station and 800 in three stations.
3. High water consumption
4. The specialist can do the repairs and maintenance of the wet press system.
Vibrating press concrete machine:
The vibrating press machine is used for production of all kinds of concrete curbstone, street paver, block (Leca-cement), and flower box. Diversity in the production of concrete products is one of the tip points of this system in relation to manufactured systems, which is the result of high production and cost apportionment. These will cause profitability and timely fulfillment of obligations and the high quality of manufactured products. It is the ever-leading movement in machine industry. All German companies have focused on this product, they have extensive studies on this kind of machinery.
Function of the machine: the density is added to the product simultaneously through vibration and press produced by the equipment of moulding.
The end of the process is formed by hydraulic pressure.
The final product is unloaded directly from the machine.
The outlet and transportation of the final product is done on a pallet.
Advantages
1. Quick compression by vibration and additional hydraulic pressure
2. The water-to-cement ratio is low so the strength of most concrete productions is high.
3. Short circulation time and fast compression and direct unloading process
4. Various shaping equipment for small and large products with the capacity to produce more than 1300 concrete products.
5. Effective production with all requirements up to a full-automatic production system
6.Very high production circle in a working shift
7. Compressive strength up to at least twice of the approved standard.
8. The ability to produce various types of concrete products, such as blocks (cement – leca – pumice), Different types of street curbstones (curbstone – canivo) and street pavers.
9. easy to maintain and work with the system

Heblex block or AAC

Autoclaved Aerated Concrete (AAC) or lightweight concrete block is also called porous concrete. The components of this block are silica, lime, cement, aluminum powder and water.

The production process

In the production line of the AAC block, there are three silos for the storage of silica, lime and cement, which enter into the production line at certain intervals. In the first step, the materials such as silica and water (wet) and lime and cement (dry) are mixed and transferred to the mold section. After chemical interactions, molds are filled and transferred to the foundry line. Molds are coated with mazut to prevent adhesion. After controlling and testing, they are carried out to the cutting line. In order to have a smooth surface, the outer surface of the mold is removed. Depending on the consumer’s demand, first the cutting process is done on width and then it is done on length by cutting machine. After finishing this step, the molds enter to the autoclave section and cook at 200 ° C and under the pressure of 12 atmospheres.

Benefits of the heblex block:

  1. Blocks with light weight, resulting in reduction of materials cost
  2. Thermal insulation
  3. Reduce the consumption of coating materials such as plaster due to the smooth surface of the block
  4. Performing in high speed
  5. Ease of installation and operation
  6. Saving on using steel
  7. Ease of practicality

Disadvantages of the heblex block:

  1. Not economical because of using silica
  2. Insufficient strength and connection to the structure
  3. Used only for non-load-bearing walls
  4. Creates crack by changing seasons
  5. Water absorption, resulting in cracks and heavy structure
  6. Product decomposition in confronting with moisture
  7. Reduced product resistance in confronting with water
  8. Not suitable for wet weather conditions
  9. High energy consumption, resulting in damage to the environment
concrete flower block

Flower box

Flower box or concrete planter, according to the materials, has many applications in various areas, including residential areas, offices, commercial complexes, cafes and restaurants, airports, and other areas. Concrete boxes are made of cement and have special molds. These boxes are designed and manufactured in industrial and semi-industrial ways in various designs and they are heavier than blocks.Some of the concrete flower boxes are made of concrete because of elaborating and using the net in their chassis, they are not heavy. This is why they are more expensive than ordinary concrete boxes in terms of price. The important thing about concrete flower boxes is that, despite their high weight, they are resistant to environmental factors. The more they expose to water, the higher their durability will be.

Machinery of Parsian Machine Sazan Tabriz are capable of producing various types of concrete flower box or concrete vase for using in sloped areas with ability to plant. Suitable molds for flower boxes are produced by Parsian, in small to very large dimensions. thus the use of concrete block flower boxes are possible in all areas.

block machine history

The brief history of the concrete block machine and concrete curbstone machine

Before concrete block machine and concrete curbstone machine become widespread, concrete molds were manually filled with concrete, and then these molds were pressed with force.
