Flashcards in Chapter 8: Brick Masonry Deck (34):
1

_____ and _____ masonry are the strongest and most durable of pre-industrial building materials.

Stone; brick

2

Seals joints; minimizes air and water flow; resistance to lateral forces from wind, such as earthquakes; contributes to wall's appearance

Mortar

3

Made up of portland cement, aggregate, hydrated lime, and water; very fine particle size of 0.0004-0.0006 in diameter

Portland cement-lime mortar

4

May include natural sand or manufactured sand

Aggregate

5

Sand provided the basic structural body of this mixture; cement binds the sand particles

Mortar mixture

6

Added ingredients to improve performance

Admixtures

7

Increasing the proportion of _____ to _____ in the mix makes a _____ compressive strength.

Cement; lime; higher

8

What are the types of mortar?

(In decreasing order of strength)

M
S (most common)
N (most common)
O
K (least common)

9

Higher-strength mortar is more _____ and have _____ workability characteristics in comparison to lower-strength mortars.

Expensive; poorer

10

Describe how bricks are formed for brick masonry.

Natural clays are excavated from the earth and screened to control particle size. Water is added to achieve a plastic consistency ready for molding into ricks.

11

Formed bricks are dried and then kiln-fired

Brick firing

12

Up to 60% void

Hollow brick

13

Appearance for exposed applications

Facing brick

14

Concealed so appearance is not important

Building brick

15

Durability, compressive strength, and water resistance

Brick grade

16

What are the 3 types of brick weathering?

Grade SW: "severe weathering" (most face brick), for any weathering
Grade MW: "moderate weathering", above grade only
Grade NW: "negligible weathering", interior and concealed

17

One horizontal row of bricks

Course

18

Horizontal joint between courses

Bedjoint

19

Vertical joint between courses

Head joint

20

One vertical stack of bricks

Wythe

21

Vertical joint between wythes

Collar joint

22

Rowlock

23

Brick laid flat, face visible

Stretcher

24

Brick laid flat, end visible

Header

25

Brick laid on end, face visible (tallways)

Soldier

26

Like soldier (tallways), broader side visible

Sailor

27

All stretchers (brick laid flat, face visible)

Running bond

28

Stretcher (brick laid flat, face visible) courses, header (brick laid flat, end visible) every 5 or 6 courses

Common bond

29

Alternating stretcher (flat, face visible) and header (flat, end visible) courses

English bond

30

Alternating stretchers (flat, face visible) and headers (flat, end visible) within each course

Flemish bond

31

When wall dimensions conform to the brick module, the need to cut the bricks is minimized.

Dimensioning

32

In brick laying, _____ (level guides) are constructed ahead of the rest of the wall; levels and string lines keep them straight.

Leads

33

Compacts joint surface, making it durable and water-resistant and neatening its appearance.

Joint tooling

34

Steel reinforcing and grouting are added to the masonry wall to increase its strength.
