1

Typical brick size is

3 5/8x 7 5/8x 2 1/4"

2

For most bricks, three courses plus mortar joints equals what height

Eight inches

3

Concrete block

Aka concrete masonry units (cmu) most common concrete block is hollow

4

Hollow concrete block is produced in many sized but commonly in

Nominal 8x8x16

5

Most common stone masonry for construction is

Granite, limestone, sandstone, slate and marble

6

Brownstone is a form of

Sandstone

7

Masonry construction can be labor intensive and mortar can deteriorate. They can be made of

Brick, terra cotta, concrete block, stone, clay tile block, gypsum block, glass

8

Masonry units have no significant tensile strength their structural application is to support what type of load

Compressive

9

Allowable compressive strength of brick masonry

250 psi

10

A chunk of brick wall 8" thick measuring 4x4 feet would weight

Appx 1,267 lbs

11

The weakest part of a masonry wall can be

Mortar joints

12

Mortar is available in five basic types with strength ranging from

75-2500 psi

13

Compressive strength of brick

2000-20,000 psi

14

Compressive strength of concrete masonry units

1500-6,000 psi

15

Mortar is mixed from

Portland cement, hydrated lime, sand, water

16

Portland cement

Most common cement chiefly using calcium and aluminum silicates. Mixed with water to form paste that hardens. Known as hydraulic cement

17

Mortar once produced without Portland cement used what as primary bonding agent

Lime

18

Most common load bearing masonry walls are made of

Brick, block, or both

19

Gypsum block and lightweight concrete block are limited to what

Non load bearing partition walls

20

Masonry walls must be thicker as they get taller because

They need to support the compressive loads of the building as well as the lateral weight of the wall itself

21

Non reinforced masonry walls are usually limited to what height

6 stories

22

Steel framed buildings are typically built with masonry veneer because

It allows cheaper construction and stability at greater bullying heights

23

Steel reinforced masonry walls can have reduced thickness. A 10 sorry building can have a wall how thick

12 inches

24

Course

Horizontal layer of individual masonry units

25

Wythe

Single vertical row of multiple rows of masonry units, typically brick

26

Header course

Course of bricks with ends facing outward

27

Multiple wythes are normally provided for strength and stability. Sometimes in conjunction with block wythes. This design is referred to as

Concrete block brick faced CBBF

28

Stretcher course of brick

Bricks placed end to end

29

Bricks placed vertically on end

Soldier course

30

Headers are used to

Provide a horizontal bond between the wythes
