Block construction involves the use of concrete or masonry blocks to build various structures, including walls, partitions, and even entire buildings. These blocks are typically made from materials such as concrete, clay, or lightweight aggregates and come in various shapes and sizes, offering versatility in design and construction. The process begins with the selection of suitable blocks based on factors like strength, durability, and thermal properties. Blocks are then laid in courses using mortar to bond them together, with techniques such as stack bond, running bond, or stretcher bond commonly employed. Block construction is known for its speed and efficiency, as blocks are uniform in size and can be easily stacked and secured. It's widely used in both residential and commercial construction due to its durability, fire resistance, and structural integrity. Additionally, block construction can incorporate insulation materials within the blocks or as external insulation to enhance thermal performance and energy efficiency. Overall, block construction offers a practical and durable solution for a wide range of building projects.
