What is CHB in Construction?
Concrete Hollow Blocks or most commonly known as CHB are the main components for concrete wall laying which is a standard dimension (0.4*0.4*0.2) rectangular block used in building construction.
What is the Standard Size of CHB?
And 8′ hollow blocks, 6′ hollow bricks, 5′ hollow blocks, and 4-inch hollow blocks are the standard sizes too. Different molds can be fitted to a set of brick machines, and different molds can produce concrete bricks of various size
A concrete brick-making machine primarily produces it. The basic components are first combined in a specific ratio. The raw materials are delivered to the brick machine’s mold, vibrated by the vibrating platform, and then produced in the mold by pressing down on the upper mold.
By using a concrete brick producing machine, hollow bricks may be produced in huge quantities while using less labor and raw resources. The hollow block that is formed also has a high strength and precise dimensions.
To create concrete hollow bricks, we can use a variety of brick-making equipment depending on the output.
They are made from cast concrete (e.g. Portland cement and aggregate, usually sand and fine gravel, for high-density blocks). But can be other material such as industrial waste, biodegradable waste and so on and so forth.
The use of blockwork allows structures and different buildings to be built in the traditional masonry style with layers of staggered blocks or the unconventional way which is straight line with more reinforcement bars in between each layers.
What is the Advantage of CHB?
Concrete hollow blocks provide a number of advantages, including being lightweight, fireproof, soundproof, heat-preserving, impermeable, earthquake-resistant, durable, pollution-free, and energy- and resource-efficient.
In the modern day, green and ecologically friendly building materials are simply necessary.
A significant component of today’s new wall materials, concrete hollow bricks have a wide development window and promising future.
In non-load-bearing areas, hollow bricks are frequently employed. The porosity percentage is equivalent to or higher than 35%. Bricks are referred to as hollow if they have numerous huge empty areas between them.
In the construction business, hollow brick is the primary type of wall material employed.
It has emerged as the first product the national construction agency recommends due to its advantages of light weight and low raw material consumption.
