ACI CONCRETE FIELD TESTING
TECHNICIAN FINAL PAPER 2026
COMPLETE QUESTIONS WITH SOLUTIONS
◉How many layers by volume is a slump cone filled? Answer: 3
layers
◉What must you do with slump cone before performing slump test?
Answer: Ensure there is no concrete build up or dents in the mold
and dampen mold before filling with concrete
◉Where must slump test be performed? Answer: On a level surface
away from vibrations
◉How large is the rod used for performing slump tests? Answer:
5/8" diameter and at least 4in taller than slump cone but not longer
than 24in
◉How many times and how far must you extend the rod into the
previous layer of concrete? Answer: 25 times and 1in into previous
layer
, ◉How do you finish the surface of the concrete in the slump cone?
Answer: Using the rod in a rolling and screeding motion
◉Prior to lifting the slump cone what must you do? Answer: Remove
any extra concrete from the base of the cone
◉How do you lift the slump cone off the concrete? Answer: Raise up
the full 12in in a continuous motion in a time period of 5sec +/-2sec
◉How long do you have to complete the slump test? Answer: Must
be complete with no interruptions in less than 2.5min
◉Where do you measure the slump? Answer: From the original
displaced center
◉What measuring device is used to determine slump? Answer:
Device marked in 1/4in increments atleast 12in long
◉How do you report the slump? Answer: To the nearest 1/4in
◉What happens if the concrete falls away or shears while lifting the
slump cone? Answer: Disregard the test and make a new test with
another portion of the sample
