Quality Concrete Construction UPDATED ACTUAL Questions and
CORRECT Answers
When used with cement in a concrete mixture, fly ash Which of the following is not a
reason to use an admixture?
reacts with calcium hydroxide, producing the same binder
as ?
Which supplementary cementitious material can improve
sulfate resistance, reduce permeability, and increase
long-term strength?
Which size aggregate will pass through a 3/8" sieve?
What unit is the water-cementitious material ratio is usu-
ally computed in?
What is an effect of diluting cement paste?
Higher slump and lower strength is the result when you
mix in more than is needed to concrete.
If you are pumping concrete out of a 5" wide line it is
recommended to mix into a 4" slump that has air
entrainment.
How does a higher water to cementitious materal affect
concrete?
Which aggregate is recommended when pumping con-
crete?
What will make the surface of concrete uniform and
skid-resistant?
If you do not presoak the concrete that is mixed with a
lightweight aggregate until at least 70 - 80% of the liquid
has soaked in, then the pumping will be .
What is the maximum amount of time a single space of
concrete should be vibrated?
