Construction Technology II

The pressure exerted by liquid concrete when placed in the form is determined by the:
1. Amount of water used.
2. Height and weight of concrete.
3. Height of concrete.
4. Weight of concrete.
As concrete is poured faster, the pressure:
1. Decreases.
2. Increases.
3. Remains constant.
4. Remains static.
What upright member is used to stiffen or reinforce the form?
1. Bulkhead
2. Keyway
3. Spreader
4. Strongback
Edge forms should be secured with braces and brace stakes:
1. At all times.
2. When sub-grade is too loose or rocky.
3. When there is wide spacing between adjacent form stakes.
4. When using wooden form stakes.
Plyform is better than regular exterior plywood for forming because it is sanded on both sides and usually has:
1. A solid core.
2. Oiled surfaces.
3. OSHA approval.
4. Rounded edges.
MINIMUM tread width for a stair form is:
1. 8".
2. 9".
3. 10".
4. 11".
How many risers are needed for stairs with a total rise of 35"?
1. 3
2. 4
3. 5
4. 6
In stair layout, the distance from the lower floor to the next floor or landing is the:
1. Head room.
2. Total rise.
3. Riser.
4. Tread.
