The first step in the brick manufacturing process is gathering the raw materials. The primary raw materials used in brick manufacturing are clay and shale. These materials are often found in abundance near the manufacturing site, making them easily accessible. Once the raw materials are gathered, they are transported to the manufacturing facility for further processing.
Once the raw materials are gathered, they undergo a series of processes to prepare the clay for brick production. The clay is first crushed and then mixed with water to achieve the desired consistency. This mixture is then refined to remove any impurities and air bubbles, resulting in a smooth and workable clay mixture that is ready for shaping.
There are different methods of shaping bricks, with the most common being the soft-mud and stiff-mud processes. In the soft-mud process, the clay mixture is extruded into a rectangular shape and then cut into individual bricks. In the stiff-mud process, the clay mixture is forced through a die to form a continuous column of clay, which is then cut into individual bricks. Once shaped, the bricks are left to dry before moving on to the next step in the manufacturing process.
When it comes to construction and engineering, one of the most important aspects to consider is the protection of the structure from the elements.
