Complete Solutions
T/F Concrete shrinks during curing and drying - ANSWER True
T/F Phased construction can introduce additional risks if elements built early
come into conflict with later design decisions - ANSWER True
T/F Piles are made of wood, steel, or brick - ANSWER False
T/F The proper curing of concrete requires sufficient quantities of water and air -
ANSWER False
T/F Fly ash is a naturally occurring volcanic ash found in the western US -
ANSWER False
T/F Zoning ordinances control how much land can be covered by buildings,
building codes with safety and health relative to the quality of construction -
ANSWER True
T/F Sandy soils typically have a lower bearing capacity than silts or clays -
ANSWER False
T/F Caissons are a slope support system for deep excavations - ANSWER False
T/F Incomplete consolidation leads to a rock pocket in the concrete wall -
ANSWER True
T/F Sloped or benched excavation is less expensive than sheeted excavation,
but requires a site without nearby property lines - ANSWER True
Methodology used for rating the environmental sustainability of a building's
design and construction - ANSWER LEED (Leadership in Energy and
Environmental Design)
Typically math occupancy type or use groups with construction types based on
fire resistance ratings - ANSWER Building codes
Used in concrete to improve workability and increases the resistance of freeze-
thaw damage - ANSWER Air Entrainment
, A concrete surface lying upon, and continuously supported by the ground -
ANSWER Slab on grade
Used to eliminate trapped air and to fill around the reinforcing steel and into all
corners of the formwork - ANSWER Vibrator
Deep foundation system used when the bearing strata (i.e. bedrock) is for below
the ground surface - ANSWER Friction piles
Occurs during concrete placement if the concrete is dropped from a substantial
height - ANSWER Segregation
Settlement occurs at variable rates typically due to soils, loads and structural
systems - ANSWER Differential settlement
Type of soil that includes sand and gravel - ANSWER Coarse grained
These wrap around the vertical bars to resists outward buckling of the bars -
ANSWER Ties
Attached to the bottom end of a riser pipe in dewatering systems - ANSWER Well
point
A manufactured product that provides the binding agent for ready-mixed
concrete - ANSWER Portland cement
Structural strength of concrete is heavily dependent on the quality of this -
ANSWER Aggregates
Used to measure the workability of fresh concrete - ANSWER Slump test
Eliminates voids and air pockets within concrete pour - ANSWER Consolidation
Very little shear strength - ANSWER Cohesionless
Strips of wood or metal are set in place to contain the concrete pour of the slab
edges - ANSWER Edge forms
Chemical bonding of water and cement - ANSWER Hydration
Applying initial compressive stress to a concrete member to improve its
structural efficiency - ANSWER Prestressing
Soldier means and logging, sheet piling, slurry wall or soil mixing - ANSWER
Sheeting
