Facing bricks are used on the outside of buildings, which means they have to be durable enough to endure rain, storms, and other unfavourable weather conditions.
Backing bricks, however, are placed behind facing bricks. So, while facing bricks must be at least mildly pleasant to look at, no one cares what backing bricks look like.
Clay is used to filling various joints brick masonry work.
Mortar joint thickness is 12 mm.
Employed for the construction of walls with a maximum height of 4 meters.
A mudbrick or mud-brick is an air-dried brick, made of a mixture of loam, mud, sand and water mixed with a binding material such as rice husks or straw.
Mudbricks are known from 9000 BCE, though since 4000 BC, bricks have also been fired, to increase their strength and durability.
This type of brick is construction done by laying bricks in cement mortar instead of masonry clay used in brickwork in clay.
There are three major classes of brickwork in cement which are summarized in the table.
Quantity of cement, Sand or Mortar Required for Brickwork1:n ratio of cementmortar is usually used for brickwork.
After adding water to the mortar mix, it bulks and reduces the volume by 33% during the wet condition. In order to calculate the dry volume of cement& sand or Brick mortar add 33% of extra volume to it.
Burnt Clay Bricks: Burnt clay bricks are also known as common bricks because they are the most abundant brick type in modern construction. These bricks are used in columns, walls, foundations, and more with a wide variety of purposes.
Sun-Dried Clay Bricks: Some DIYers might prefer to make these simple sun-dried clay bricks, which have been used as far back as 7,000 BC in southern Turkey and around the city of Jericho in modern-day Palestine.
Concrete Bricks: Typically used in internal brickwork or to make facades and fences, these bricks are made from solid concrete. The concrete is poured into custom molds, allowing manufacturers to create a variety of sizes and shapes.
Engineering Bricks: As the name suggests, engineering bricks are a favorite of structural engineers because of their high compressive strength and density, ideal qualities for use as load-bearing materials.
Sand Lime Bricks: Made using a mixture of sand, lime, and possibly a color pigment to alter the final appearance of the brick, sand lime bricks have a high compressive strength, so they are a common option for load-bearing walls in houses and multi-storied buildings.
Fly Ash Bricks: Fly ash is a byproduct produced by coal-fired power plants that can contain toxic metals like mercury, arsenic, antinomy, and chromium.
Firebricks: If the goal of the masonry project is to create a structure, wall, or framework that is highly resistant to heat and fire, then firebricks are the best material.
