1. The specific gravity of an aggregate is the ratio of its unit weight to
the weight of an equal absolute volume of: - ANSWER ✓ Water
2. What is the weight of a bag of Portland cement in the USA? -
ANSWER ✓ 94 lbs
3. What is the maximum concrete temperature allowed when using a
hot weather design mix? - ANSWER ✓ 100 degrees F
4. Who is responsible for signing the FDOT delivery ticket at the
concrete plant? - ANSWER ✓ The FDOT qualified batch plant
operator
5. The number of mixing revolutions at mixing speed, at the plant
will be recorded on the delivery ticket: - ANSWER ✓ Before
leaving for the jobsite
6. When filling out the information for aggregates on the delivery
ticket, which of the following is NOT required? - ANSWER ✓ The
target weight of the aggregate batch.
,7. The amount of water added at the jobsite should be signed for by
the: - ANSWER ✓ Contractor's representative
8. What is Type I Cement? - ANSWER ✓ General use - everyday
cement
9. What is type II Cement? - ANSWER ✓ Moderate soleplate
resistance cement
10. What is type III cement? - ANSWER ✓ high and early
strength cement- grind finer than type I and II, costs more energy
and not as sustainable
11. What is Type IV cement used for? - ANSWER ✓ low heat
application cements- concrete damn or huge concrete column - not
used anymore, fly ash or slag is used now.
12. Type V - ANSWER ✓ High soleplate resistance cement.
13. What is white cement? - ANSWER ✓ Reacts similar to
Portland cement but very low amounts of iron - it is not actually
white, it is slightly yellow- used for making concrete with
consistent coloring.
14. What are microfibers used for? - ANSWER ✓ To avoid
plastic shrinkage in concrete - holds concrete together while its
wet.
15. What are Macrofibers used for? - ANSWER ✓ To maintain
strength of the concrete when the it hardens.
, 16. What is an air entraining admixture? - ANSWER ✓ Adds
SOAP into the concrete helps to split bubbles in concrete mixes.
SOAPs are surfactants - containing a hydrophilic head and
hydrophobic tale which align themselves around the bubbles in
concrete- they attract cement grains- helps to hold the bubble in
place and form a shell material around the bubble to prevent air
from exchanging between the bubbles.
17. Concrete is a mixture of _____, ______, and ______. -
ANSWER ✓ cement, water, and aggregates.
18. The most commonly used concrete for structural purposes is:
- ANSWER ✓ Normal weight concrete.
19. Normal weight concrete weighs approximately: - ANSWER
✓ 140 lb/ft^3
20. Lightweight structural concrete may weigh from _____ to
______ lb/ft^3. - ANSWER ✓ 90, 100
21. Heavyweight concrete may weigh ______. - ANSWER ✓
200 lb/ft^3 or more.
22. Most concrete today is made with: - ANSWER ✓ Portland
Cement
23. Concrete is usually referred to as a mixture of two
components; ______ and _______. - ANSWER ✓ aggregate, paste
24. The hardening process of the paste is a chemical reaction
called _________. - ANSWER ✓ Hydration
