Flashcards in Bricks, Stone & Glass Deck (20):
1

What materials can bricks be made from (4)

Clay, calcium, silicate, concrete

2

How are clay bricks produced

By firing shaped clay units to a temperature of about 1000 degrees c

3

What is an important factor when determining the frost resistance of a Clay Brick.

Size distribution and degree of inter connectivity of pores

4

What are the three types of clay bricks

Common, Facing, Engineering

5

Why should allowance within the building design be made with regards to expansion in bricks

Bricks are ale to draw in moisture from the surrounding air

6

What materials form Calcium silicate bricks

flint, sand, lime

7

What is the main advantage of using calcium silicate bricks

Highly resistant to frost damage and contain hardly any soluble salts.

8

How are Igneous stones formed

from molten magma that cools rapidly

9

what are the two main types of Igneous Stone

Basalt, Granite

10

What forms sedimentary stone

small particles of igneous rocks such as quartz with fragments of decayed animal or vegetable matter.

11

In sedimentary stone, what bonds together the quartz and decayed animal matter

silica, calcium carbonate, clay, iron oxide.

12

Sedimentary stones have natural bedding planes which mean their bonding is...

Weak

13

What are the two main types of Sedimentary Stone

Sandstone and Limestone

14

What is Metamorphic Stone

Stone which has been changed by heat or pressure thus increasing its crystallinity.

15

What are the two main types of metamorphic stone

Marble, Slate

16

How is slate formed

by introducing high pressure to clay to form shale, and then introducing heat to form slate.

17

What is inorganic glass

fusion products which have failed to crystallise on cooling to room temperature.

18

What are the three common types of glass

soda lime silicate glass (common glass), borosilicate glass (pyrex), alumino silicate glass (fibre glass)

19

What is the mechanical definition of glass

it's an elastic brittle solid which is extremely sensitive to stress concentrating effects of surface defects.

20

Windows are commonly made from what two types of glass

toughened glass, laminated glass
