CHB stands for "Concrete Hollow Block." It is a commonly used construction material made of cement, aggregates, sand, and water which are molded into a rectangular shape with hollow cavities inside. CHBs are widely employed in the building industry for various structural applications, providing strength, durability, and ease of construction.
The use of CHBs offers several advantages. Firstly, their hollow design reduces the weight of the blocks, making them lighter and easier to handle during construction. This feature also allows for improved thermal insulation and better soundproofing properties. Moreover, the cavities inside the blocks can be filled with reinforcing materials like steel bars to enhance strength and enhance overall structural integrity.
CHBs come in different sizes to suit specific construction requirements. The most common dimensions are typically 390mm (length) x 190 mm (height) x 90 mm or 190 mm (width). These blocks can be laid using mortar or adhesive in various patterns such as stack bond, running bond, or herringbone.
Due to their cost-effectiveness, CHBs are extensively used in both residential and commercial construction projects. They are often employed for external and internal walls, retaining walls, partitions, fences, and other load-bearing structures. The utilization of CHBs contributes to sustainable construction practices as they are made from readily available materials and are recyclable.
In conclusion, CHB refers to a type of construction block made of concrete with hollow cavities. They are versatile, durable, and cost-effective, making them a popular choice in the building industry for various structural applications.
