Bricks can be composed of clay-bearing soil, sand, and lime, or concrete materials. It has been used as a building material for at least 5,000 years. A brick will be produced in numerous classes, types, materials, and sizes and are also produced in bulk quantities. They are a building material used to make walls, pavements and other elements in masonry construction. Since they are fire resistant it means that they are also perfect for building houses and other structures. As well as this, they are aesthetically pleasing.
What are bricks made of?
In order to make the main body of the brick, natural clay minerals are used. To produce different shades of brick, little amounts of barium, manganese and other products are mixed with the clay. To improve a brick and its chemical resistance to the elements, barium carbonate is used. During a chemical-transforming process in the kiln, the minerals in the clay fuse together and become brick.
Bricks tend to be four inches wide and twice as long. Since each brick is small it’s a perfect material for structures in small spaces. A benefit of using this material is that they have minimal upkeep and that brick buildings tend to last a long time.
Different methods of manufacture:
A mud brick is an unfired type of brick. This type of brick is made from a wet, clay-containing soil mixed with straw of similar binders. The brick is then air dried until ready for use.
A fired brick is durable as it is burned in a kiln. Modern, fired, clay brick is formed in one of three processes: soft mud, dry press or extruded. The extruded or soft mud method is the most popular depending on the country. This is due to the fact that they are the most economical.
A Chemically Set Brick
This type of brick is not fired but may have the curing process accelerated by the application of heat and pressure in an autoclave.
