What is Hollow Block?

 

Hollow Block, in General, is a Type of Concrete Block Used for building internal and external walls. Hollow concrete Block saves time in building walls due to its large dimensions. Due to the load-carrying capacıty, the Hollow Block is playing an important role in the construction industry.

Hollow blocks are one of the many options as construction materials. They are made using molds and a suitable additive depending on your location and your project. It is believed that concrete blocks are one of the most popular construction materials which are used in the construction industry almost everywhere. Especially cement is used to bond components in order to produce stronger and longer life hollow blocks.

The composition of hollow concrete block:

As an additive any of the below materials can be used:

1. Volcanic ash
2. Granite rubble
3. Sand
4. Broken glass, brick, concrete, hardened cement
5. Expanded clay
6. River gravel or crushed stone
7. Sawdust
8. Some combustion products: boiler slag, ash.

 

hollow block is considered as inexpensive material, therefore, used by builders quite often.

Regarding the properties and appearance of hollow cement block, it is presented in the following varieties:

  • solid concrete block:

solid concrete blocks are used for laying the foundation, columns, supporting structures of buildings, basements. The leading role is played by their durability.

 

Concrete hollow block with emptiness inside is used as a building material in the construction of walls and partitions of a building. They are lighter, so they do not add to the total weight of the structure too much.

 

  •  Decorative facing concrete hollow block:

Appeared on the building materials market not so long ago. Their distinctive feature is the presence of a decorative coating on one or two sides. This layer of the concrete hollow block not only duplicates various textures (stone, plaster) but also performs a protective function - makes it resistant to moisture. Due to this, there is no need for complex finishing work.

 

  • Partition concrete hollow block:

They are used in the laying of partitions and have some advantages: accurate wall geometry is observed, solution saving, low weight compared to brick, quick installation.

 

  • Colored concrete hollow block:

Used in construction on a par with conventional materials, hollow blocks are most often used in the construction of fences, gables, decorative pillars. They achieve the desired shade already at the stage of hollow block manufacturing process. To do this, crushed red brick or colored chalk is added to the mixture.

 

  • Base concrete hollow block:

Their other name is an artificial wall stone. It differs in durability and durability in use, does not shrink and does not crumble. A prerequisite for laying the foundation of concrete hollow blocks is the presence of reinforced concrete tape, which must have a layer of at least 1.5 centimeters. The walls of the foundation blocks are necessarily covered with hydro and heat insulation.

 

This building material has a decorative surface under the "ragged" and crushed concrete hollow block. It is used most often as a cladding for fences and decoration of buildings or structures.

The hollow block is also known as hollow cement block or hollow concrete block as well. It is sometimes called a concrete masonry unit as well. the shapes and sizes of most common concrete blocks have been standardized to ensure uniform building construction. So, we made a hollow block machine producing hollow blocks. The machine has this feature. It works for 24 hours. Has different Automation and capacity system. The machine is very fast and has a high production capacity. Except for product drying and curing rooms, there is no extra equipment needed in the plant area. we design different options, manual hollow block machine, Semi-Automatic concrete block machine, and fully automatic block making machine.

What is the standard size of a hollow block?

Normally the size of a standard hollow block is 20cm(width) * 40cm(length) * 20cm(height) this is a worldwide standard and the manufacturers produce their hollow blocks considering this standard.

Advantages of Using Hollow Blocks:

Hollow blocks are important masonry units in construction. here I am sharing some advantages of using the hollow block in buildings and construction:

1. Rapid Execution of Work in construction

hollow cement blocks are produced by hollow block machine also known as concrete block machine in different shapes, sizes, and weight. it is easy to deploy hollow blocks in construction works, all that is needed is to fit the right block to the right place. Using the same shape and sizes help to easily assemble them to form any particular shape that is required in the construction area.

2. Extremely durable

the hollow block produced by high pressure and vibration make the blocks very strong, resilient hardened to severe load and weight.

3. Better Insulation

As hollow blocks have holes and because of the air in the hole of the block, it does not allow heat or cold in or out of the building. Hollow blocks are insulated against heat, wetness, and sound. Hollow blocks keep the house cool in summer and warm in winter.

4. Environmentally friendly

It does not infect or have any known environment frustration it constitutes to the system.

5. Cost-Efficient

Hollow block helps in reducing construction materials used at a construction site, though reducing the cost of construction.

6. Low Maintenance

Maintenance of hollow block structures is not expensive, compared to other construction materials that are available in the market.

7. Reduce consuming Space

Construction of thin walls with hollow block is very common. So, it helps to reduce space used in construction and increases the floor area.

8. Bonding of mortar and plaster

As the surfaces of hollow blocks are rough, this provides a good bonding between mortar and plaster.

because there is nothing in the whole world that has only advantages and not one single disadvantage, let's talk about the possible disadvantages of the hollow block:

1.Appearance:

Unfortunately, many people still have the impression that a hollow block is unsightly and utilitarian, but technology has advanced significantly and now these hollow blocks can be treated with various render products and techniques, allowing you to create impressive finishes that look a lot more expensive than they actually are.

Even different colors are added to the mortar these days to produce different colors of blocks. This way you can have the exact color of the hollow concrete blocks you have in mind for the facing of your building and interior walls as well.

2.water absorption:

Another problem with the hollow block is its ability to absorb water. We are all familiar with the expansion strength of water when it freezes, so we can understand that a retaining wall, one that is in constant contact with the earth behind it, would be wet most of the time. This cannot be said for the wall of a building that is protected from the rain on the outside and is open to the air on the inside. When the temperature goes below freezing for a long period of time, it freezes the ground, it will also freeze the water in the hollow block supporting your retaining wall. Though it may take a few years, depending on the number of freezes you have each year, eventually, cracks will begin to form in both the hollow block and the mortar used to hold them together.

The manufacturing process of hollow blocks:

Maybe you wonder how a hollow block is made, it is made of cement, water and aggregate mixed together with a standard ratio, about the machine which produces hollow blocks, it is called hollow block machine or brick making machine.

this machine has different molds and each mold can produce a different shape and size of a hollow concrete block. Hollow block machine uses pressure and vibration to compress the mortar, so the produced hollow blocks have better quality. The pressing force is usually 150 Bar and vibration force is normally 36.500kg.

Producing hollow block is a very profitable business. The hollow block is very much in demand due to the advantages of it over other options. And due to the population growth, the need for housing is growing as well. There are many brick making machine manufacturers in different countries with different capacities and prices, so you have many options to choose among them.

Hollow cement block is produced on pallets first and when they are dried, they are delivered to euro pallets for international transportation.

Conclusion:

It will be best to take some time analyzing all aspects, the pros, and cons of each application, and try to think of it in the long run. If you are also interested in the costs, then the hollow concrete block is the solution for you.
