SOLVED QUESTIONS GRADED A+
◉ The slump test is used for what. Answer: Used to measure the
consistency of the concrete. It gives an indication to the flowability /
workability / plasticity of the concrete.
◉ What are the most important benefits of air entrainment. Answer:
Improves the concretes resistance to freezing / thawing cycles &
improves concrete resistance to deicing chemicals.
◉ How the compressive strength of concrete measured. Answer: By
testing concrete cylinders (usually 6" diameter and 12" high) in the
laboratory.
◉ What is the main reason for concrete test cylinders. Answer: To test
the strength of the concrete at a given time.
◉ What is the typical test for concrete cylinders. Answer: Two cylinders
are created and their strength is tested at 28 days. The average of the two
is the strength of the concrete.
, ◉ Is the 7th day strength test for concrete part of the strength evaluation
for the concrete. Answer: No the test is for informational purposes only.
◉ The 7th day strength test is anticipated to be what level of strength of
the 28 day strength test. Answer: 65% - 70%
◉ What chemical reaction takes place when concrete is hardening.
Answer: Hydration
◉ What is the most common type of portland cement used in
construction. Answer: Type 1
◉ What type of portland cement is considered to be high early strength.
Answer: Type III
◉ The quality of the cement mix depends primarily on the -. Answer:
Water cement ratio
◉ A 3/8" sieve is used for what. Answer: To determine what is a coarse
aggregate and what is a fine aggregate. The coarse aggregate will not
pass through the sieve.
◉ What type of sand is not suitable for aggregate. Answer: Fine sand
