Accelerators
Which materials are used to reduce heat of hydration and increase workability?
Pozzolans
What is the process of proportioning cement, water, and aggregates prior to mixing?
Batching
Which admixtures are mostly used in pumped concrete to produce a mix that flows easily?
High-range water-reducing admixtures (super plasticizers)
What are rubber or vinyl inserts placed in joints to prevent water penetration?
Waterstops
What is it called when dry materials settle and displace mixing water to the surface?
Bleeding
Which finishing step rounds off slab edges to prevent chipping?
Edging
What are fine hair cracks in a newly hardened slab caused by surface shrinkage?

Tack coat
Which mat foundation has excavated soil weight approximately equal to structure weight?
Floating foundation
What condition occurs when water pressure exactly equals soil weight?
Liquefaction
What is the perforated assembly placed at the bottom of a well inlet pipe?
Wellpoint
What horizontal beam provides additional strength and prevents cracking in masonry?
Bond beam
Which path through a network establishes the minimum project duration?
Critical path
What are fixed costs incurred each year whether equipment is used or not?
Owning costs
Which bond guarantees a contractor will provide performance/payment bonds if awarded?
Bid bond
What is the percentage of work value withheld as a guarantee against defective work?
Retainage or retention
What is the list of deficiencies prepared at the final inspection called?
Punch list of record
Which database relates design data, drawings, and life cycle data to present an overall project view?
Building Information Modeling (BIM)
Which machine is very versatile and has the longest reach for digging and dumping in the crane-shovel family?
The dragline
These are primarily used for lifting, lowering, and transporting loads by swinging or traveling.
Cranes
This represents those components of cycle time other than travel time.
Fixed time
This represents the travel time required for a unit to haul material to the unloading site and return.
Variable time
The process of densifying cohesionless soils by inserting a vibratory probe into the soil is called:
Vibratory compaction (vibroflotation)
This involves dropping a heavy weight from a crane onto the ground surface to achieve soil densification.
Dynamic compaction
Placing additional weight on the soil surface to densify cohesive soils is known as:
Surcharging
The process of bringing earthwork to the desired shape and elevation is called:
Grading
This involves smoothing slopes, shaping ditches, and bringing earthwork to the exact elevation required by plans
Finish grading
Normal-weight concrete usually weighs how many pounds per cubic foot?
140 to 160 lb/cu ft
Which type of concrete is used in structures like dams where the weight of the material provides the strength?
Mass concrete
Concrete made with heavy aggregates like barite or steel punchings for nuclear radiation shielding is:
Heavyweight concrete
This refers to concrete having a slump of 1 inch (2.5 cm) or less.
No-slump concrete
Concrete suitable for high-temperature applications such as boilers and furnaces is:
Refractory concrete
This is concrete that has been cast into the desired shape prior to placement in a structure.
Precast concrete
Which type of Portland cement provides better resistance to alkali attack and produces less heat of hydration than Type I?
Type II
Which type of cement produces only 40-60% of the heat of Type I during the first 7 days?
Type IV
Which type of cement provides maximum resistance to alkali/sulfate attack?
Type V
What is the heat produced by the chemical reaction between cement and water called?
Heat of hydration
This type of concrete has significantly increased resistance to freezing, thawing, and scaling from deicing chemicals.
Air-entrained concrete
These increase the slump or workability of a concrete mix without changing its consistency.
Water-reducing agents
These admixtures slow down the rate of hardening of concrete.
Retarders
