Question 1

The interlocking of masonry Chapters to each other to distribute the weight of the wall is call a _____ .&#10;A) mortar bond&#10;B) structural bond&#10;C) pattern bond&#10;D) construction bond

Accepted Answer

The interlocking of masonry chapters to distribute the weight of the wall is called a structural bond. This is because it provides strength and stability to the wall by evenly distributing the weight and forces acting on it. A mortar bond refers to the way the mortar is applied between the bricks or blocks, while pattern bond refers to the pattern in which the bricks or blocks are laid. Construction bond is a general term that can refer to any type of bond used in construction.

Question 2

Truss-type joint reinforcement is not recommended by BIA engineers for use in cavity walls or brick veneer with masonry backing.

Accepted Answer

BIA (Brick Industry Association) engineers do not recommend truss-type joint reinforcement for use in cavity walls or brick veneer with masonry backing as it can cause cracking and mortar joint failure due to differential movement between the inner and outer wythes of the wall. Alternative reinforcement methods, such as ladder-type joint reinforcement or horizontal joint reinforcement, are recommended.

Question 3

The adhesion of mortar to the masonry Chapter, wall ties, or other means of reinforcement is known as the _____ .&#10;A) mortar bond&#10;B) structural bond&#10;C) pattern bond&#10;D) construction bond

Accepted Answer

The adhesion of mortar to masonry, wall ties, or other means of reinforcement is specifically referred to as "mortar bond." While "structural bond" and "construction bond" may also refer to the adhesion of mortar to reinforcement materials, they are broader terms that can encompass other aspects of building construction. "Pattern bond" refers to the specific arrangement and design of masonry units in a wall.

Question 4

It may be possible to secure many different patterns with the same structural bond by mixing various colors and textures.

Accepted Answer

By using a variety of colors and textures, it is possible to create different patterns while still utilizing the same structural bond.

Question 5

When using metal ties embedded in the mortar, _____ of wall surface.&#10;A) no more than one metal tie should be used for every 5 square feet&#10;B) no more than three metal ties should be used for every 5 square feet&#10;C) at least one metal tie should be used for every 4&#189; square feet&#10;D) at least five metal ties should be used for every 4&#189; square feet

Accepted Answer

Metal ties embedded in mortar are used to increase the structural integrity of masonry walls. The correct guideline is that at least one metal tie should be used for every 4½ square feet of wall surface to ensure proper support and stability.

Question 6

The _____ brick position is laid with the widest side of the brick in a horizontal position exposed on the front of the finished wall.&#10;A) shiner&#10;B) soldier&#10;C) rowlock&#10;D) sailor

Accepted Answer

The shiner brick position involves laying the brick with its widest side horizontal and exposed on the front of the finished wall, creating a broad and flat appearance.

Question 7

The stretcher is laid in a vertical position with the shortest, widest side exposed at the front of the wall.

Accepted Answer

A stretcher bond in bricklaying is laid horizontally with the longest side of the brick exposed, creating a long, continuous line.

Question 8

Mortar is the first material you use when laying any masonry Chapter.

Accepted Answer

Mortar is necessary to bond the masonry units together, so it is always the first material used in masonry construction.

Question 9

The term bond has several different meanings to the masonry student or apprentice.

Accepted Answer

Bond can refer to the pattern in which bricks or other masonry units are laid, as well as to the adhesive material used to adhere them together.

Question 10

A _____ allows the moisture to drip from the center of the tie into the cavity rather than across the cavity to the other wall.&#10;A) stretcher bond&#10;B) lapping pattern&#10;C) metal tie&#10;D) dip crimp

Accepted Answer

A dip crimp allows the moisture to drip from the center of the tie into the cavity rather than across the cavity to the other wall.
