The type of wood typically used in construction.
What is softwood?
100
In steel production, coal, limestone, and iron ore are reduced to this material.
What is pig iron?
100
Elements added to aluminum (in general) giving the material up to 15-times the strength of pure aluminum.
What are alloys?
100
Natural petroleum-based polymer that is typically heated and mixed with aggregate to provide pavement for roadways.
What is asphalt?
200
The specified length plus the thickness of the mortar joint.
What is the nominal length?
200
Inner layer of wood that provides strength and is resistant to decay.
What is heartwood?
200
Increasing this alloy, increases the strength and hardness of steel while decreasing the ductility and melting point.
What is carbon?
200
The metallic, atomic structure of pure aluminum.
What is face-centered-cubic (FCC)?
200
Asphalt is an example of this type of polymer.
What is thermoplastic?
300
The most commonly used classification of concrete masonry units (CMU's).
What are light-weight units?
300
Moisture content below which shrinkage occurs.
What is the Fiber Saturation Point (FSP)?
300
The process of heat treating steel by heating the metal and then cooling rapidly using cold water.
What is hardening?
300
This is the impure aluminum containing material that is extracted from the earth.
What is Bauxite?
300
A category of polymer that does not soften upon heating.
What are thermosets?
400
CMU required to support 1700 psi per individual unit.
What is a load-bearing CMU?
400
A wood defect in which an opening between annual rings contains free resin.
What is a pitch pocket?
400
The chemical process by which steel, water and oxygen combine to create corrosion or rust.
What is oxidation?
400
Corrosion that occurs when aluminum is in contact with another metal in the presence of water.
What is galvanic corrosion?
400
An atom or molecule replacing a hydrogen atom in a carbon-hydrogen polymer chain.
