WOOD CONSERVATION Flashcards
(13 cards)
1
Q
Purpose of Conservation
A
- Enable wood to continue to function as load-bearing structural member
- Enable the wooden object to carry its own weight (possible with some support)
2
Q
Wood Defects
A
- Knots, Warps, and Cracks
- Termite, Fungal, and Pest Infestation
- Decay of Wooden Elements
- Misalignment and Sagging of Wood Supports
3
Q
Causes of Knots, Warps, and Cracks
A
- Abnormal growth of tree
- Shrinking due to loss of moisture
- Wood imperfections
4
Q
Consequences of Knots, Warps, and Cracks
A
- Unsightly appearance
- Weakening of wood
- Visual flaws
5
Q
Causes of Termite, Fungal, and Pest Infestation
A
- Softening wood due to water leaks
6
Q
Consequences of Termite, Fungal, and Pest Infestation
A
- Softening (leads to possible collapse of wood support)
- Unsteady structure
7
Q
Causes of Decay of Wooden Elements
A
- Collection of water in motise joints
- Water leaks
- Rot
- Insect manifestation
8
Q
Consequences of Decay of Wooden Elements
A
- Falling out of the bottom of the post
- Collapse of members
- Shaky support (weak wood members)
9
Q
Causes of Misalignment and Sagging of Wood Supports
A
- Poorly maintained roofing
- Leaking roofs and plumbing pipes
- Past earthquake damages
- Wood boring insects
- Termites
10
Q
Consequences of Misalignment and Sagging of Wood Supports
A
- Falling out of wood pegs
- Appearance of cracks on the wood
11
Q
(3) Primary Reasons to Conduct Wood Assessment
A
1) Concerns about moisture and its effects
2) Deterioration physical, biological
3) A need to know material properties (strength)
12
Q
Deterioration of Wood can be a result of:
A
- Physical processes (weathering, failure—overload, shrinkage)
- Biological processes (decay, insect attack)
13
Q
(3) Tools for Basic Wood Inspection
A
- Visual Inspection (High Subjective)
- Sharp Probe
- Moisture Meter
