Today, many clay bricks are made in purpose-built molds. Properties: Bricks are highly refractory, not commonly used because of high shrinkage at high temperature Chromite Fire Bricks: neutral class of refractories. Whichever molding method you use, aim to produce clay bricks of the same size and shape. Its history traces back thousand years (almost 7500 BCE). Clay bricks and Concrete blocks are the most popular building construction materials. Redbrick is a building unit, made up of clay, sand, lime, and other ingredients in proportion. 2.Fire clay brick has advantages of fireproof and heat insulation. They also form a very important class of Basic Refractories. Their other plus points are that they’re low maintenance and long lasting. Traditionally, clay bricks were molded by hand or with wooden tools. Brick Defined . If we pay attention to the strength and durability, brick proves to be back here as compare to stone masonry. ix) Unlike clay bricks, they do not require soaking in water before usage.
