Question 1

_____ brick is intended to support pedestrian or light vehicular traffic.

Accepted Answer

Paving brick is specifically designed to withstand the weight of pedestrians and light vehicles, while thin brick refers to cut brick that is thinner than standard building brick, facing brick is used for the exterior masonry walls of a building, and building brick is used for general structural purposes.

Question 2

Modern manufacturing processes and the use of automatic equipment _____ .

Accepted Answer

Modern manufacturing processes and the use of automatic equipment can lead to minor variations in color and texture of bricks, as these processes aim for efficiency and consistency but cannot completely eliminate natural variations in materials.

Question 3

Glazed brick, similar to that made 2000 years ago, are still made today.

Accepted Answer

Glazed brick-making techniques have been preserved over the years, and certain manufacturers still produce them using the same process as in ancient times.

Question 4

For brick making, two or more kinds of clay and shale may be mixed together to obtain a material having the proper consistency and composition.

Accepted Answer

Mixing different types of clay and shale is a common practice in brick making to achieve the desired consistency and composition.

Question 5

To keep brickmaking and bricklaying secrets confined to their own groups, early masons _____ .

Accepted Answer

Early masons banded together in organizations called guilds to keep their brickmaking and bricklaying secrets confined to their own groups. Guilds had strict codes of conduct and apprenticeship requirements, and only members were allowed to learn and practice the trade secrets.

Question 6

The recessed panel at the bottom of brick manufactured today is called a _____ .

Accepted Answer

The recessed panel at the bottom of brick manufactured today is called a frog.

Question 7

In modular design, the _____ dimension of a masonry Chapter means that the specified or manufactured dimension plus the thickness of the mortar joint being used.

Accepted Answer

The nominal dimension is the specified or manufactured dimension of the masonry unit. In modular design, this dimension includes the thickness of the mortar joint being used, which is typically around 3/8 inch. The module refers to the overall design dimension, while course refers to the horizontal layer of masonry units. The term brick is a specific type of masonry unit, not a dimension.

Question 8

_____ act as fluxes and promote fusion at lower temperatures during brickmaking.

Accepted Answer

Metallic oxides, such as calcium oxide (CaO) and sodium oxide (Na2O), act as fluxes and promote fusion at lower temperatures during brickmaking. They help to lower the melting point of the clay mixture and increase its plasticity, making it easier to manipulate and form into bricks.

Question 9

_____ are found near the surface of the earth.

Accepted Answer

Surface clays are found near the surface of the earth as the name suggests. Shales are sedimentary rocks that can be found at various depths, compressed clays are formed under high pressure and are not necessarily found near the surface of the earth, and fire clays are special types of clay that are used to create fire-resistant materials and are not always found near the surface.

Question 10

The Chaptered States Federal Trade Commission has ruled that no product made from materials other than clay or shale can be called brick with unless the name includes the material from which the Chapter is manufactured.

Accepted Answer

The statement accurately describes a ruling made by the Federal Trade Commission.

Question 11

The actual mortar joint size can be determined from the _____ coursing information and the specified Chapter size.

Accepted Answer

The answer of The actual mortar joint size can be...

Question 12

All clay and shale react in the same manner to processing methods used in brick making.

Accepted Answer

While clay and shale are both commonly used materials in brick making, they can have different properties and require different processing methods depending on their specific composition. Therefore, they do not necessarily react in the same manner to processing methods used in brick making.

Question 13

Brick from the same production run will always have uniform color and texture.

Accepted Answer

While bricks from the same production run will have similar color and texture, factors such as variations in temperature and moisture during the firing process can still lead to some differences in appearance between individual bricks.

Question 14

The acceptable industry standard for chipped brick usually is not more than _____ percent of the exposed face area of a brick wall or project.

Accepted Answer

The acceptable industry standard for chipped brick is usually not more than 5% of the exposed face area of a brick wall or project. A limit of 15% would be too high and result in a poor-quality appearance, while a limit of 1% would be too restrictive and impractical to achieve. Therefore, the best choice is C - 5%.

Question 15

Cored brick are those that _____ .

Accepted Answer

Cored bricks are characterized by having holes through their width, which can reduce the weight of the brick and improve its insulating properties. These holes are typically perpendicular to the bed of the brick, not necessarily at the bottom, and are part of the manufacturing process.
