ALREADY GRADED A+ (BRAND NEW VISION)
perpendicular, eccentricity - answersThe third point loading method shall be used in making
flexure tests of concrete employing bearing blocks that will ensure that forces applied to the
beam will be ______ to the face of the specimen and applied without ______.
1.- +- .003 - answersThe ration of the horizontal distance btween the point of application of the
load and the point of application of the nearest reaction to the depth of the beam shall be
_________
True - answersHand-operated machines can't be used in this testing method if they have pumps
that don't provide continuous loading at a uniform rate
+-1mm +-.05in - answersThe testing equipment must be capable of maintaining distances
between load-applying and support blocks constant within_____ mm or _____ in.
a and c – answers Which of the following are requirements for load-bearing and support
blocks?
a) they should be 65 mm (2.5 in) high or less
b) The should be half as wide as the specimen
c)they should be in contact with the rod or ball
Scars, indention, holes, inscribed identification marks - answersTest specimens should be
smooth and free of _____,______, ______, or ______
, True - answersIn relation to the applied force, the loading system should be centered during the
procedure. True or False?
use of shims, grinding, cutting – answers during the testing, if suitable contact is not made
between the specimen and bearing block surfaces ____, ____, or ____ may be required
surface, .4mm .015 in - answersIt is acceptable to use leather shims only when the gap
between the specimen ____ in contact with the blocks is not more than ____ mm or _____ in.
3, dimension – answers To determine the average width, depth and line of fracture location of
the specimen, you should take _____ measurements across each ______
b – answers Discard the test results when the fracture occurs in which of these instances:
a) outside the middle third of the span length but by less than 5% of the span length
b) outside the middle third of the span length by more than 5% of the span length
c) within the middle third of the span length
false, include cap thickness - answersif a fracture occurs at a capped section , you should not
include the thickness of the cap in your calcualtaions. True or False?
tension surface within the middle 3rd of the span length – answers The formula, R=PL/bd^2
measures the modulus of rupture at which location?
1mm, .05 in – answers The final report should include both the average width and depth to the
nearest _____ mm or _____ in
