Bricks come in various types, including common, facing, engineering, and technical bricks. Each has unique characteristics and uses. Common bricks are low quality and used for internal masonry, while facing bricks are high quality and used for aesthetic purposes. Engineering bricks are extremely hard and durable, while technical bricks are resistant to frost and moisture.
Bricks can be used in a variety of ways and there are many types of bricks to meet the requirements of the construction industry. They can provide structural integrity or have decorative value. Bricks come in many forms, such as hollow bricks, solid bricks, and cored bricks. While different types of bricks may look similar, they vary greatly in their composition and possess unique characteristics. Some of the most important types of bricks are common bricks, facing bricks and technical bricks.
Common bricks are also called hard bricks or building bricks and are made of clay. These bricks are typically of lower quality than the other types of bricks and are not suitable for underground construction. They are mainly used for internal masonry and have low compressive strength. The color and surface texture of common bricks can vary greatly as no attention is paid to these aspects when fired in a kiln.
Facing bricks are bricks made from a mixture of water, clay, and sand. They are mostly used for aesthetic purposes to give buildings an attractive exterior look. These bricks are of much higher quality than common bricks and possess greater strength and durability. They are specifically fired for use in exposed wall surfaces and are able to withstand all types of weather and environmental conditions.
There are many colors, styles and sizes of facing bricks and they are designed to be visible. In general, facing bricks cannot be used freestanding due to their inability to withstand enormous weight or stress and require support in some way. They possess the greatest degree of uniformity, however, of all other types of bricks. Facing bricks are used for highly detailed architectural work.
Engineering bricks are made to be extremely hard. They go through a complex process to achieve a high degree of compressive strength. The clay is carefully selected, fired and shaped to give the resulting bricks greater strength and durability. These bricks are stronger than other types of bricks and can withstand a lot of wear and tear. They have a low water absorption rate and are extremely resistant to moisture.
Of all the types of bricks, technical bricks are the most resistant to frost and are mainly used for construction in wet and frozen environments. As well as being used extensively to build walls below ground level, they are also used on sites where it is important for the bricks to be extra strong or moisture resistant. They are classified as Class A or B bricks, depending on their compressive strength and water absorption capacity.
