BUILDING STONES Flashcards
used in construction
durable, tough and free from soft patches of weathered materials
building stones
formed by cooling and
solidification of lava.
igneous rock
3 igneous rocks
basalt
granite
serpentine
– medium to fine
grained stone
-waterproof
basalt
–coarse grained
-durable but has poor
resistance to fire
granite
– used for

- formed by metamorphosis of clays
- separated into thin tough
sheets called slates.

WHICH IT IS AVAILABLE
COMMERCIALLY
‘rubble
‘dimension (cut stone)
‘flagstone (flat slab)
‘crushed rock
- includes rough fieldstone
which merely have been broken into
suitable sizes (usually used for
filling material).
rubble
- consist of
pieces that have been cut or finished
according to a set or drawings (for
facings of walls)
