Masonry Flashcards
the average size of a brick and weight
102, 215,65 mm
2-4 kg
Why are the bricks used?
fits in the hand of a bricklayer leaves a 10mm gap between each brick easy to transport cheap accessible
Engineering brick
looks a specific properties
- compressive strength
- water absorption
used to support heavy loads and/or minimise water absorption
2 classes A and B
Common brick
no visual finish
used in unseen finised work
Facing brick
attractive finish
visual brickwork
Earliest Bricks
mud and clay
Catal Huyauk
- Hand-molded and then sunbaked
How are bricks made now?
formed by extrusion and baked in a kiln
What is the gap left between bricks
10 mm
Maunfacturing bricks process
extraction forming drying (100%) firing packaging and distribution
What does placinf vertical joints over each other do?
redcues the strength, vertical joint should be half way over the next brick
Advantages of masonry
exonomical - raw material durbale healthy spatial climate reusable and recyle fire-resiatnt low-maintance cost
Weakness of masonry
time-consuming production
not suitable for high seismic zones
efflorescence = due to rainwater leakage
Spalling = aborbs water than freezes
Colour could change to sunlight exposure
limited high of buildings = lack of internal strength
brick manufacture is a high energy process
