CCIL Concrete Testing Technician
Certification - A23.2-3C Exam Questions
With Correct Answers.
A23.2-3C
1. Scope - ANSWER-This Test Method specifies the procedure for making and curing
compression test cylinders and flexural test beams from samples of plastic concrete.
Procedures for both field and laboratory work are included.
ACI - ANSWER-American Concrete Institute
A23.2-3C
3. Summary - ANSWER-This Test Method is used to cast compressive or flexural
strength test specimens and cure them on site prior to timely transportation to the
laboratory for subsequent curing and strength testing.
A23.2-3C
4. Significance and use - ANSWER-This Test Method specifies the standard procedure
for making, curing, protecting, and transporting concrete specimens.
4. Significance and use
If the specimens are made and standard cured as specified in this Test Method, the
resulting strength data, when the specimens are tested in accordance with the relevant
test method, may be used for the following purposes: - ANSWER-1. acceptance testing
for specified strength;
2. checking adequacy of mixture proportions for strength; and
3. quality control
4. Significance and use
If the specimens are made and field-cured as specified in this Test Method, the resulting
strength data, when the specimens are tested in accordance with the relevant Test
Method, may be used for the following purposes: - ANSWER-1. consideration of
whether the structure is able to be put into service;
2. comparison with test results of standard cured specimens or with test results from
various in place test methods;
3. adequacy of curing and protection of concrete in the concrete structure; and
4. formwork or shoring removal time requirements.
5. Apparatus
5.1 Moulds for compression test specimens: - ANSWER-Use cylindrical moulds,
meeting the requirements of CSA A23.2-1D, having nonabsorbent surfaces and
sufficiently rigid to hold their shape during the moulding of the test specimens.
Do not use cardboard moulds for specified concrete strengths greater than 35 MPa.
