(13 cards)
Most common considerations in deciding construction materials
- Climate
- Economics
This construction material usually comes from a major part of the trunk and branches of a tree. It is characterized by its hard and fibrous surface. Commonly used as doors, frames, windows, partition walls, roof trusses, ceilings and formworks.
Wood
used to bind coarse and fine particles together to produce concrete
cement and concrete, cement
a viscous material derived from the refining of petroleum products
bitumen
primary ingredient for making bricks
clay
used to supplement the strength afforded to the structure by concrete
metals
Properties of Engineering Materials
Physical, Chemical, Mechanical
properties that can be observed or tested without changing the chemical composition or structure of the material.
physical properties
some examples of physical properties
density
bulk density
specific gravity
weight
porosity
void ratio
water absorption
properties are usually observed during a chemical reaction, during hydration of cement
chemical properties
properties demonstrate the material’s failure mechanism
mechanical properties
some examples of mechanical properties
strength
hardness
elasticity
rupture
plasticity
Selection of Materials
strength
serviceability
aesthetics
cost
environmental effect
