Question 1

Cutting of concrete block should be kept to a minimum.

Accepted Answer

Cutting of concrete block should be kept to a minimum to maintain the integrity and strength of the structure. Excessive cutting can weaken the block and compromise the overall structure.

Question 2

_____ is a term meaning that the mortar has adhered to the masonry Chapter.&#10;A) Dry&#10;B) Set&#10;C) Bond&#10;D) Seal

Accepted Answer

Set refers to the process where the mortar has hardened and adhered to the masonry units.

Question 3

When masonry Chapters are laid or stacked directly over one another with the head joints in plumb vertical position, it is called _____ .&#10;A) stack-over-stack&#10;B) stack design&#10;C) jack work&#10;D) jack-over-jack

Accepted Answer

When masonry chapters are laid or stacked directly over one another with the head joints in a plumb vertical position, it is referred to as "jack-over-jack." This method aligns the vertical joints from one course to the next, creating a continuous vertical seam.

Question 4

In high-quality masonry work, every head joint must be kept exactly plumb with those on alternating courses below.

Accepted Answer

This is correct. Maintaining plumb head joints in masonry work helps ensure structural integrity and aesthetic appeal.

Question 5

A concrete block wall built in the stack bond must be full stretchers.

Accepted Answer

In a stack bond, the blocks are stacked directly over each other with the joints aligned vertically. This method does not necessarily require the blocks to be full stretchers; it focuses on the alignment of the joints rather than the length of the blocks.

Question 6

Creating a _____ means that every head joint is kept exactly plumb with those on alternating courses below.&#10;A) straight course&#10;B) uniform distribution&#10;C) plumb bond&#10;D) alternating bond

Accepted Answer

Plumb bond refers to a masonry bond where the vertical joints are aligned to make sure the wall is straight and even. This is achieved by keeping every head joint aligned exactly plumb with those on alternating courses below. A straight course is a bond pattern where all the bricks or blocks are aligned horizontally in the same direction. Uniform distribution relates to the even spreading of materials or objects in a specific area. An alternating bond is a type of masonry bond where header courses are placed after every few stretcher courses.

Question 7

Concrete blocks of _____ are the only blocks that lap perfectly over each other without the necessity of cutting the corner block.&#10;A) 6&#34;&#10;B) 7.5&#34;&#10;C) 8&#34;&#10;D) 10&#34;

Accepted Answer

Concrete blocks with a size of 8" are the only blocks that lap perfectly over each other without the need to cut the corner block. The other sizes mentioned (6", 7.5", and 10") will require cutting to achieve a smooth lap.

Question 8

_____ concrete blocks are made with projected vertical ribs on the face of the block for a rustic appearance.&#10;A) Fluted&#10;B) Projected&#10;C) Piped&#10;D) Ribbed

Accepted Answer

The answer of _____ concrete blocks are made with projected...

Question 9

Bonding brick and concrete block together is known as composite masonry wall.

Accepted Answer

This statement is true. Composite masonry walls are created by bonding bricks and concrete blocks together to form a single structural unit.

Question 10

The procedure for establishing a running bond in block is the same as that described for brickwork.

Accepted Answer

The statement is true. The procedure for establishing a running bond is the same for both brick and blockwork.
