, CE 200 FINAL EXAM QUESTIONS AND
ANSWERS 100% CORRECT!
the fine aggregate sieved and reported above does not qualify for use in portland
cement concrete because: - ANSWER more than 45% of the sieved sand has passed
one sieve and retained in the consecutive standard sieve
ASTM C 136, "standard test method for sieve analysis of fine and coarse aggregates",
requires that the nest of sieves used for sieve analysis be agitaded for an appropriate
amount of time, such that, every individual sieve, having been weighed subsequent to
every shaking, would not have the mass of its content vary by more than 1% in
consecutive shakings: - ANSWER because, over-sieving the sand would cause
breaking the sand particles into smaller pieces and indicate the sand to be finer
it may be said about sieve analysis that: - ANSWER none of the above is true
the primary purpose of using a sand sample splitter in sieve analysis is to; - ANSWER
none of the above is true
a limitation of using the fineness modulus for determining aggregate acceptability for
use in portland cement concrete i s that the FM - ANSWER test results from fineness
modulus tests provide no indication on other attributes of the aggregate important for
use in concrete, such as moisture content, water absorbance, friability, surface texture,
etc
the types of cements used as binders, or as primary component of binders, may be
grouped as hydraulic or non-hydraulic cements: - ANSWER all of the above:
pc is the leading hydraulic cement used in civil engineering
asphalt is the leading nonhydraulic cement used in civil engineering
lime, a non-hydraulic cements, that used to be dominant cement employed in masonry
before the discovery of roman cement
another hydraulic cementitious material-i.e. a hydraulic cement other than portland
cement is - ANSWER all of the above:
pozzolana or volcanic ash which obrains its cementing capability after reacting with
hydrated lime
fly ash or the ash from smokestacks of coal-burning furnaces
