Actual size of brick/ nominal size of brick
Bricks are one of the oldest building materials used by humans and have been an integral part of construction for centuries. They are a staple in both residential and commercial buildings, and their size plays a crucial role in determining the strength and stability of a structure. The size of a brick is measured in two different ways – actual size and nominal size. In this essay, we will delve into the actual and nominal size of bricks and their importance in civil engineering.
The actual size of brick refers to the dimensions of the brick after it has been fired in a kiln. They are the exact measurements of the brick when it is manufactured. The actual size may vary slightly depending on the type of brick, manufacturing process, and country of origin. However, in most cases, the actual size of bricks is standardized to ensure consistency and compatibility between different manufacturers.
Typically, the standard dimension of a brick is 3 ⅝ inches (9.2 cm) in height, 2 ¼ inches (5.7 cm) in width, and 7 ⅝ inches (19.4 cm) in length. These measurements may vary slightly, with some bricks being slightly larger or smaller. Bricks used for structural purposes, such as load-bearing walls, may have larger dimensions to provide more strength and stability to the structure.
On the other hand, nominal size of brick refers to the dimensions of the brick minus the mortar joint. In other words, it is the size of the brick after taking into account the thickness of the mortar joint used to lay the bricks. The nominal size is usually ⅜ inch (9.5 mm) larger than the actual size. For example, a standard brick with an actual size of 2 ¼ inches by 3 ⅝ inches by 7 ⅝ inches would have a nominal size of 2 ⅝ inches by 4 inches by 8 inches.
The difference between actual and nominal size of bricks is crucial in civil engineering. When designing a structure, engineers use the nominal size of bricks to calculate the number of bricks needed for the project. This is because the thickness of the mortar joint must be taken into account to ensure proper spacing and alignment of the bricks. The actual size of bricks is used when determining the strength and stability of the structure, as it takes into account the dimensions of the individual bricks.
In addition to actual and nominal size, bricks also have a standard specification for compressive strength. The average compressive strength of bricks can range from 7.5 MPa to 25 MPa depending on the type of brick and its composition. This strength is crucial in determining the load-bearing capacity of a structure, and it must be considered when designing buildings that will be subjected to external forces such as wind and earthquakes.
In conclusion, the actual and nominal size of bricks play a significant role in civil engineering. The actual size provides the exact measurements of a brick, while the nominal size takes into account the thickness of the mortar joint when laying bricks. Both these sizes are important as they determine the strength and stability of a structure. As such, it is essential for engineers to carefully consider the actual and nominal size of bricks when designing a building to ensure its safety and durability.

What is called frog in brick size?
Frogs in brick size refer to the indentations found on the top and bottom surfaces of bricks. They are small semi-circular or triangular shaped recesses that are formed by pressing wet clay into a wooden mold, before it is fired in a kiln. These indentations, also known as “frog” or “kicker”, are an essential component of brick construction.
The purpose of frogs in brick size is to provide better bonding between the brick and the mortar. When bricks are laid in a wall, the mortar is placed between the joints of the bricks to hold them together. The mortar fills the spaces in the bricks, creating a strong and stable structure. The presence of frogs in the brick allows for more mortar to be applied, resulting in a larger surface area of contact between the brick and the mortar. This increases the bond strength and prevents the bricks from easily shifting or falling out of place.
Furthermore, the indentations created by frogs also allow for better ventilation and drainage within the wall. As bricks are stacked upon each other, gaps or voids are created between them. These gaps can become potential pathways for moisture to seep into the wall. The presence of frogs can reduce this risk by creating a space for air and moisture to circulate and escape through the gaps, preventing any buildup of moisture that can lead to damage or decay of the bricks.
Apart from their functional benefits, frogs in brick size also serve as a visual indicator for bricklayers during construction. They help ensure that the bricks are laid in the correct orientation and are the same height. This results in a more uniform and aesthetically pleasing finished product. In addition, the depth of the frogs also helps to determine the strength of the brick. Bricks with a deeper frog tend to be stronger and more durable.
The size and design of frogs can vary depending on the type of brick and its intended use. For example, bricks used for paving may have larger and deeper frogs to provide better traction and drainage, while bricks used for structural purposes may have smaller and shallower frogs to reduce weight and increase strength.
In conclusion, frogs in brick size serve important functional and structural purposes in brick construction. They enhance the bond between bricks and mortar, aid in ventilation and drainage, and provide visual and structural guidance during construction. The presence of frogs is a key aspect to consider when choosing the right type of brick for a specific construction project.
