Item at position 38
A type of construction where the walls are poured on the foundation slab and then lifted with a crane and braced for final assembly is called:
Architectural concrete
Shotcrete
Tilt-up
Two-way flat slab
Item at position 39
The purpose of an isolation joint is:
To create regular lines in the concrete rather than irregular cracks
To isolate water run-off and provide a channel to drive water to collection point
Architectural and aesthetic
Allow for expansion and contraction of a slab next to another slab or wall
Item at position 40
The purpose of tooled in or saw-cut control joints are to
Architectural and aesthetic
Allow for expansion and contraction of a slab next to another slab or wall
To create regular lines in the concrete rather than irregular cracks
To isolate water run-off and provide a channel to drive water to collection point
Item at position 41
The purpose of steam curing in the production of pre-stressed concrete elements is:

Weld to a beam support
Support a beam
Item at position 46
What are the advantages of pre-cast concrete compared to site-cast concrete (Circle all that apply)
Ability to pre-stress the reinforcement to create a stronger unit
Efficient use of formwork
Limitless sizes and shapes are possible

Item at position 48
What are the advantages of pre-cast concrete compared to site-cast concrete (Circle all that apply)
All-weather construction
Efficient use of materials. Little waste
Curing of concrete within 24 hrs
Longest spans possible
Item at position 49
What is a casting bed?
Used to manufacture pre-stressed concrete elements
Laid between two pre-stressed concrete elements to reduce grinding
Used to lay pre-stressed concrete elements into
A layer of carbon reinforcement for column-beam connection
