ACI - 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.
